Converged innovation: SoFi Stadium’s networks break new ground

When you spend more than $5 billion building a revolutionary-looking new sports and entertainment venue, it’s a good bet that the technology found inside is the best that can be found.

What’s truly innovative at the new SoFi Stadium in Los Angeles is not just the quality and functionality of the technology’s pieces and parts, but also the venue’s embrace of a converged network design, where all network-attached devices connect to a single Cisco Catalyst-based network.

Led by Skarpi Hedinsson, chief technology officer, SoFi Stadium and Hollywood Park, and master technology integrator AmpThink, the networking and compute environment deployed inside the building (as well as in Hollywood Park’s neighboring retail, commercial and residential area) is unlike most large venues, where different systems typically exist in their own silos, often with their own separate and different network.

Instead, the SoFi Stadium network brings all building functionality – including the wireless networks (among the largest built anywhere), the server compute platform, the telephone system, the IPTV network, the indoor and outdoor digital signage (including the massive oval dual-sided 4K main videoboard), the television broadcast systems, and the building management systems – into one converged platform, with a single vendor/single format structure.

“What we delivered is a scalable platform that simplifies Day 2 operations on Day 1,” said AmpThink president Bill Anderson.

Over the coming months, Stadium Tech Report plans to do deep technical dives on each segment of the stadium’s different technology deployments. Consider this story a sort of “executive summary” that will attempt to at the very least introduce all the technology elements that are part of the stunning new venue, which hosted its first NFL games for both stadium tenants, the Los Angeles Rams and the Los Angeles Chargers, in early September.

Converged network a revolution for stadiums

If the stunning architecture of SoFi Stadium and its innovative elements like the oval, dual-sided videoboard represent the realization of Rams owner and Hollywood Park developer Stan Kroenke’s “art of the possible,” then the converged network and its interlocking technologies perhaps represent “the art of the practical,” at a scale somewhat unprecedented inside a large public venue.

If you poke your head inside older sports venues, you are most likely to see separate networks and operation centers for many of the different systems – wireless, wired networks, broadcast, and building operations. Historically the case has been made that those who know those systems best are responsible for building their operations – but the silo approach often brings headaches to those in charge of overall operations for the venue as a whole, as they deal with the proliferation of different systems to operate and manage.

AmpThink, which has deployed networks in more than 70 venues across the country, pioneered the idea of a single, converged stadium network when it built the prototype at the 14,000-seat Dickies Arena last year. But the size and scope of the converged network project at SoFi Stadium – which will hold 70,000 fans for NFL games and up to 100,000 for special events like the Super Bowl – was much larger. Still, according to AmpThink’s Anderson, the planned outcome was the same: to deliver the best outcome for the customer.

“It all works together, because it’s designed to work together,” said Anderson. “Instead of fighting to see if one switch works with another, you can focus on the business.”

With 120 separate remote telecommunications rooms – including some hardened for hot weather conditions in the outside areas of Hollywood Park – the SoFi Stadium converged network is designed to present a “single pane of glass” management structure, where there are no “islands” requiring special attention.

Even the live video production system, usually a completely separate entity, is run on a connected Cisco Nexus switched environment. Every telecommunications closet or cabinet is directly connected via fiber to the campus core. According to AmpThink, all the telecom rooms have edge switches that use 25 Gbps optics and a minimum of two connections per closet/cabinet to provide an aggregate of 50 Gbps of campus interconnectivity.

The blanket of Wi-Fi and cellular coverage

On the Wi-Fi side, the SoFi Stadium network is the biggest AmpThink has built in a stadium, with approximately 2,400 APs inside the venue and another 300 in the surrounding Hollywood Park area. For the full Wi-Fi 6 Cisco deployment, AmpThink used an under-seat deployment in the main bowl. Before expanding to include full stadium technology integration, AmpThink made its name in successful big-venue Wi-Fi network design and deployment, with networks built most recently at Mercedes-Benz Stadium in Atlanta, and last year at Ohio State and Oklahoma University, the first two large-stadium networks to move exclusively to the new Wi-Fi 6 standard.

In a commitment to offering the best possible connectivity to consumer devices no matter which network they use, the Wi-Fi and cellular distributed antenna system (DAS) at SoFi Stadium were both designed to each provide 100 percent venue coverage. The DAS, designed and deployed by DAS Group Professionals using gear from JMA Wireless, is the largest ever deployed. According to Hedinsson, the network has 2,400 antennas and 3,200 remotes, and is capable of covering all licensed spectrum bands between 600 MHz to 6 GHz.

As cellular carriers move toward the 5G future, the DAS is capable of supporting all the low- and mid-band spectrum currently planned for use. According to Hedinsson, there will also be millimeter-wave 5G services in the stadium, from a carrier to be named later. The stadium networks are supported by 50 Gbps backbone links.

Bringing data center strategies to the stadium

While hyper-convergence of server use is common in the data center space, that has traditionally not been the case in sports and entertainment venue operations. But the eventual compute network built for SoFi Stadium’s operations even surprised AmpThink’s Anderson, whose company originally estimated a compute environment with perhaps 20 to 30 virtual machines.

As it stands now, Anderson said the compute environment has almost 100 VMs, which host applications for all the network operations as well as varied building management needs like power, light, HVAC, security, and even specialized systems like irrigation and seismic monitoring. Instead of a mix of servers running siloed applications on separate physical machines with different operating systems, the SoFi Stadium compute environment is a unified platform and includes a seamless integration into Google Cloud, allowing it to be easily scaled to meet current and future needs.

A digital stadium with displays big and small

Any discussion of digital displays at SoFi Stadium has to start with the main videoboard, a one-of-a-kind design of a 120-foot long oval that circles the playing field, with dual-sided 4K screens, some 40 feet in height. (Please see our detailed profile of the main videoboard in our recent Venue Display Report.)

The digital display footprint goes far beyond the main screen, with some 2,600 other smaller boards deployed throughout the venue and in Hollywood Park. According to Hedinsson, the ability of the Cisco Vision display management system is a key part of the “digital stadium” design, especially when you consider that the venue has two main tenants, each with their own branding and look and feel.

“Being digital means we can switch over the branding [by changing displays] instead of physically having to move signs,” said Hedinsson. “That’s why we have Cisco Vision. We have digital ‘playbooks’ for the different scenarios, and we can just push them out as needed.”

Innovation and experience leads the technology deployment at Raiders’ Allegiant Stadium

If it looks somewhat like a spaceship, perhaps that’s appropriate since the arrival of Allegiant Stadium has brought to Las Vegas something alien that residents thought they might never see: live NFL games, happening just off the city’s famed Strip.

As befits its futuristic appearance, the new home of the newly named Las Vegas Raiders is also fitted with the latest in fan-facing technologies, deployments that will have to wait a bit before their potential can be realized.

Though the $1.9-billion, 65,000-seat stadium “officially” opened on Sept. 21 with a 34-24 Raiders victory over the New Orleans Saints, a decision made by the team earlier in the year meant that no fans were on hand to witness the occasion. But when fans are allowed to enter the building, they will be treated to what should be among the best game-day technical experiences anywhere, as a combination of innovation and expertise has permeated the venue’s deployments of wireless and video technologies.

With a Wi-Fi 6 network using equipment from Cisco, and an extensive cellular distributed antenna system (DAS) deployment by DAS Group Professionals using gear from JMA Wireless and MatSing, integrated fiber, copper and cable infrastructure from CommScope, backbone services from Cox Business/Hospitality Network, digital displays from Samsung, and design and converged network planning directed by AmpThink, the Raiders have used an all-star team of partners to reach the organization’s desire to provide what Raiders’ vice president of IT Matt Pasco calls “a top-notch fan experience.”

Finally getting to build a stadium network

Editor’s note: This story is from our recent STADIUM TECH REPORT Fall 2020 issue, which you can read right now, no email or registration required! Also in this issue is a profile of the technology behind SoFi Stadium in Los Angeles. START READING NOW!

For Pasco, who is in his 19th year with the Silver and Black, the entity that became Allegiant Stadium was the realization of something he’d never had: A stadium network to call his own.

From 1995 until the end of last season, the then-Oakland Raiders played home games in the Oakland Alameda County Coliseum, where they were tenants and shared the building with MLB’s Oakland Athletics.

According to Pasco, since the Raiders didn’t have the ability to direct capital improvements, “we never got to build a sufficient DAS, and we never got to have sufficient Wi-Fi for all our fans.”

Fast-forward to the plans that eventually took shape with the move of the team to Las Vegas, and for a change Pasco was able to start thinking about what that meant from a technology perspective. With his long tenure and relationships around the league, Pasco said he embarked on a several years-long “stadiums tour” of accompanying the team for road games, looking at what other teams had done at their venues.

“I kept a big notebook on what I liked, and what didn’t seem to work,” Pasco said. “I sat down with a lot of my counterparts and talked about what worked well, and what they had to spend time with. So I got a really good sense of what was possible.”

Wi-Fi 6 arrives just in time

One fortunate event for Allegiant Stadium’s wireless deployment was the 2019 arrival of equipment that supported the new Wi-Fi 6 standard, also known as 802.11ax. With its ability to support more connections, higher bandwidth and better power consumption for devices, Wi-Fi 6 is a great technology to start off with, Pasco said.

“We were very fortunate that Wi-Fi 6 was released just in time [to be deployed at Allegiant Stadium],” Pasco said. “The strength of 802.11ax will pay off in a highly dense stadium with big crowds.”

The Raiders’ choice of Cisco as a Wi-Fi provider wasn’t a complete given, even though Pasco said that the team has long been “a Cisco shop” for not just Wi-Fi but for core networking, IPTV and phones.

“We did look at Extreme [for the new build] but Cisco just has so many pieces of the stack,” Pasco said. “Things like inconsistencies between switch maker A and IPTV vendor B are a little less likely to happen. And they’ve done good things in so many buildings.”

Pasco also praised the Wi-Fi network design and deployment skills of technology integrator AmpThink, which used an under-seat deployment design for Wi-Fi APs in the main seating bowl. Overall, there are approximately 1,700 APs total throughout the venue.

“I am thrilled with the work AmpThink has done,” said Pasco, who admitted that as a network engineer, he had “never done” a full stadium design before.

“They [AmpThink] have built networks at more than 70 venues, so they came highly recommended,” Pasco said. “And meeting their leadership early on sold me pretty quickly.”

Part of what AmpThink brought to the stadium was a converged network design, where every connected device is part of the same network.

Innovation abounds in the DAS

If the Wi-Fi world is already moving forward with general availability of Wi-Fi 6 gear, the cellular side of the equation is in a much different place as carriers contemplate how to best move forward with their latest standard, 5G.

For venues currently adding or upgrading a DAS, the 5G question looms large. One of the hardest things about planning for 5G is that the main U.S. cellular carriers will all have different spectrum bands in use, making it hard to deploy a single “neutral host” DAS to support all the providers. Currently, all previous 5G deployments in stadiums have been single-carrier builds – but that won’t be the case in Allegiant Stadium, thanks to some new gear from JMA.

Steve Dutto, president of DGP – which used JMA gear at many of its other stadium DAS installations, including the San Francisco 49ers’ Levi’s Stadium and most recently at the Texas Rangers’ new home, Globe Life Field – said the DAS deployed at Allegiant Stadium “is like no other” NFL-venue cellular network.

“By selecting JMA DAS equipment we were able to deploy a [5G standard] NR radio capable system from day one,” Dutto said. “This means that all carriers can deploy 5G low- and mid-band technology without any additional cost or changes to the DAS system.”

According to Dutto and JMA, the JMA TEKO DAS antennas cover all major licensed spectrum used, from 600MHz to 2500 MHz. and will provide ubiquitous coverage over the entire stadium.

“Carriers will be able to deploy their 4G technologies along with their low- and mid-band 5G technology over all of the stadium coverage area,” Dutto said. “No upgrades will be required. All carriers will need to do is provide their base radios in the headend.”

According to Todd Landry, corporate vice president, product and market strategy at JMA, the TEKO gear used at Allegiant Stadium “employs an industry unique nine-band split architecture, placing lower frequency bands in different radios than higher frequency bands.” This approach, Landry said, lets the stadium “optimize the density of higher band cells versus lower bands” while also reducing the total number of radios needed for low bands by half.

Landry said the JMA gear also has integrated support for the public safety FirstNet spectrum band, and is software programmable, allowing venue staff to “turn on” capabilities per carrier as needed, eliminating on-site visits to install additional radios or radio modules. According to DGP the DAS has 75 high-band zones and 44 low-band zones in the main seating bowl, with a total of 117 high- band and 86 low-band zones throughout the venue.

Adding in the MatSing antennas from above

One twist in the DAS buildout was the addition of 30 MatSing lens antennas to the cellular mix, a technology solution to potential coverage issues in some hard-to-reach areas of the seating bowl. According to Pasco the Raiders were trying to solve for a typical DAS issue – namely, how to best cover the premium seats closest to the field, which are the hardest to reach with a traditional top-down DAS antenna deployment.

“We looked at a hybrid approach, to use under-seat [DAS] antennas for the first 15 or 20 rows, but the cost was astronomical,” Pasco said. “We also heard that [an underseat deployment] may not have performed as well as we wanted.”

The MatSing antennas, which are ball-shaped and support greater distance between antenna and end-device, were already designed for use in the Allegiant Stadium “Peristyle” gathering area, where there is a large open space where fans are expected to gather – with a large top-down distance between the area and the struc- tures where antennas are mounted.

“I had heard about the full MatSing deployment at Amalie [Arena] and wondered if we could do that,” said Pasco. Fortunately for the Raiders, the architecture of the stadium, with a high ring supporting the transparent roof, turned out to be a perfect place to mount MatSing antennas, which use line-of-sight transmission to precisely target broadcast areas. For Pasco, a move toward more MatSings was a triple-play win, since it removed the need for other antennas from walkways and overhangs, was less costly than an under-seat network, and should prove to have better performance, if network models are correct.

“It is the perfect marriage of cost reduction, better performance and aesthetics,” said Pasco of the MatSing deployment. “We even painted them black, like little Black Holes,” Pasco said. “It’s one of the most innovative decisions we made.”

“We are excited to be part of the Allegiant Stadium network,” said MatSing CEO Bo Larsson. “It is a great venue to show the capability of MatSing Lens antennas.”

Supporting wireless takes a lot of wires

Behind all the wireless antenna technology in Allegiant Stadium – as well as behind the IPTV, security cameras and other communications needs – sits some 227 miles of optical fiber and another 1.5 million feet of copper cable, provided by CommScope.

A good balance of the 100 Gbps fiber connections are used to support the stadium’s DAS network, with the capacity built not just for current needs but for expected future demands as well. According to CommScope senior field applications engineer Greg Hinders the “spider web of single-mode fiber” includes multiple runs of 864-strand links, which break out in all directions to support all the networking needs.

For the cable connections to the Wi-Fi gear, CommScope’s design went with Cat 6A cable, which has double the capabilities and a longer reach than standard Cat 6.

“The new APs really require it [Cat 6A] so we went standard with Cat 6A throughout the building,” Hinders said.

And if the job wasn’t tough enough – limited construction space at the stadium required that CommScope and its distribution partner Anixter had to stage its network in an offsite warehouse – CommScope also had to make sure that exposed wiring was colored silver and black to match the stadium design and the team’s colors.

While single-mode fiber is usually colored yellow, Hinders is enough of a football fan to know that Pittsburgh Steelers colors wouldn’t fly in the Raiders’ home.

“It all had to be black and grey,” said Hinders. “Black and yellow isn’t good for the Raiders.”

The MatSing antennas also posed a challenge for CommScope, since each MatSing antenna requires 48 individual connections for all the radios in each device.

“It was [another] logistical challenge,” said Hinders. “But it was great to see [the entire network] all come to fruition. It’s nice to know we had a part in putting it all together.”

Providing enough backbone bandwidth

To ensure that Allegiant Stadium had enough backbone bandwidth to support all its communications needs, the Raiders turned to Cox Business/Hospitality Network, a partner with considerable telecom assets in the Las Vegas area.

Jady West, vice president of hospitality for Cox, noted that not only does Cox have experience in providing data services to high-demand venues (including State Farm Stadium in Glendale, Ariz., which routinely hosts big college games and the Super Bowl), it also has a wealth of resources in and around Las Vegas, providing services to the big casino hotels and the Las Vegas Convention Center.

With a 100 Gbps regional network, West said Cox is able to bring “quite a bit of power and flexibility” to the equation. Having supplied services to big events like CES at the LVCC, West said, “takes a specialized skill, and that’s what my team does. This is what we do.”

Specifically for the Raiders, Cox built two 40-Gbps redundant pipes just to serve the needs of Allegiant Stadium. Additionally, Cox built a 10 Gbps metro Ethernet link between the stadium and the team’s headquarters and practice facility in nearby Henderson, Nev., a connection that Pasco said would be essential for stadium operations as well as the on-field football business.

“Both the video production staff and the football staff can now push information back and forth like we’re in the same building,” said Pasco, who gave high praise to Cox’s work. From a production side, crews at headquarters can create content for videoboards and displays, and have it at the stadium instantaneously; similarly, video from the stadium’s field of play or from practices can be shared back and forth as needed, in a private and real-time fashion.

West said Cox, which also provides game-day network support and a “NOC as a service” solution, knows that the data demands of the big-time events that will likely be held at Allegiant Stadium will only keep increasing, and it built its systems to support that growth.

“The most demanding events are things like CES, and NFL games,” West said. “This network is built for the future, to hold up for all those events.”

Videoboards to fit the design

Last but certainly not least in the technology arsenal at Allegiant Stadium are the Samsung videoboards. Above the south end zone, the largest board measures approximately 250 feet long by 49 feet high, according to Pasco. Two identical sized boards of 49 feet by 122 feet are in the corners of the north end zone. Including ribbon boards, Pasco said there is a total of 40,000 square feet of LED lights inside the seating bowl.

On the stadium’s exterior there is another large videoboard, a 275-foot mesh LED screen that fits in perfectly with the bright lights of the city’s famed Strip. Inside, the venue will also have approximately 2,400 TV screens for information and concessions, with all the systems controlled by the Cisco Vision display management system.

Boingo to bring Wi-Fi 6, DAS to Austin FC’s new stadium

Austin FC has selected Boingo to deliver a neutral-host distributed antenna system and a Wi-Fi 6 network for the club’s new stadium, which is slated to open next year during Austin FC’s inaugural season in Major League Soccer.

While all scheduled things for sports and stadiums are currently “pending” due to the coronavirus pandemic, for right now the new venue located in the north-central part of the booming west Texas metropolis is still slated to open next year, according to Andy Loughnane, Austin FC President. And in a phone interview this week Loughnane said that when the stadium does open up, it should have the kind of connectivity that Austin’s tech-savvy populace will expect — namely, strong Wi-Fi and cellular.

According to Loughnane, Boingo emerged as the winner of a “competitive process” to choose the technology supplier for the venue. While some of the details of the networks have not yet been announced — including hardware vendors for both the DAS and the Wi-Fi networks — Loughnane and Boingo are confident that the stadium will have more than enough bandwidth to keep a full house of 20,500 soccer fans (or 22,000 concertgoers) well connected no matter where they are.

No matter which Wi-Fi vendor is selected, Loughnane said that using Wi-Fi 6 APs will be a performance key for what he hopes will be fully packed stands (if and when fans are allowed to attend large events again). Boingo senior vice president and general manager Doug Lodder said that the Wi-Fi network will use a combination of under-seat and overhead AP deployment, with “hundreds” of APs throughout the venue.

Dodgers up the ante with new Wi-Fi 6 network

Professional sports may have put games and exhibitions on hold, but a handful of IT executives from Major League Baseball teams have been using pandemic downtime to upgrade Wi-Fi and DAS systems in their stadiums.

Case in point: The Los Angeles Dodgers just completed the league’s first Wi-Fi 6 overhaul along with adding new 5G cellular antennas to ensure Blue Believers stay seamlessly connected to social media, email, text and good old-fashioned voice calls during home games. When baseball returns to venues, Dodger Stadium and the new Globe Life Field in Arlington, Texas, will lead the way as the first stadiums with Wi-Fi 6 fan-facing networks.

“We’re up against the same challenges that every stadium has, which is how to deal with the density of individuals trying to connect simultaneously – a challenge that’s unique to our industry,” explained Ralph Esquibel, vice president of IT for the Dodgers. “Wi-Fi 6 was created for this kind of high-density environment.”

Wi-Fi 6, better known in IEEE circles as the 802.11ax standard, is a significant upgrade for Wi-Fi networks that started appearing last year. Among its benefits are that use of the new standard can increase the amount of available spectrum and number of channels available for users; it can also significantly accelerate users’ average data rates, while also decreasing the amount of battery power used by devices searching for a Wi-Fi connection.

As long as they have newer phones that support the new standard, Wi-Fi 6 networks provide everything a team could want for its connection-conscious fans.

Replacing the Wi-Fi 4 network

Like its predecessor, the Wi-Fi 6 network will use under-seat APs in the bowl

It’s been barely five years since the Dodgers installed Wi-Fi 4 in the stadium, making use of under-seat APs and what were the league’s first APs cleverly concealed inside hand railings for even denser coverage. There were about 900 APs powering the network then, which easily accommodated 8,000 simultaneous users on its maiden voyage.

“It was state of the art back at that point in time,” Esquibel recalled. But usage and uptake quickly soared among fans and it wasn’t long before 30,000 simultaneous users were contending for bandwidth at each game.

“That was when I’d get a call from previous ownership, usually sometime in the second inning with, ‘I can’t get on email or make a phone call…’,” Esquibel laughed. Suddenly, it didn’t matter how close your seat was to home plate; anybody watching the game became inadvertent victims of Wi-Fi’s highly successful rollout at Dodger Stadium.

Other baseball stadiums experienced similar capacity and uptake issues. That’s in part what prompted MLB to dispatch its technology committee to look at technology upgrades to make sure baseball fans could do all the wireless networking they wanted to while watching a game. Though MLB did not respond to a request for more information, STR was able to get some information from other sources about the pending upgrade plans.

Wi-Fi 6 coming to more ballparks

According to our sources, MLB technologists settled on Wi-Fi 6 upgrades as their next strategic push. So while the Dodgers will be the first baseball team to upgrade to Wi-Fi 6, other teams were also reportedly in the first steps of adding Wi-Fi 6 before the coronavirus pandemic put a hold on many upgrade plans.

More APs were added in overhangs and roofed areas

It’s unclear if the MLB technology committee brought any financial help to the table along with their wireless expertise for these six upgrades. When MLB put together a consortium to bring wireless connectivity to parks starting back in 2014, it got financial buy-in from wireless carriers, equipment vendors and teams to help spread the costs around. Esquibel wouldn’t specify any dollar amounts for the Dodgers’ Wi-Fi 6 budget or whether the league contributed anything. He did note that the team negotiated an upgrade clause into its previous Wi-Fi networking contract.

Construction for the Dodgers’ new network began last fall, right after the Dodgers lost to the Washington Nationals in the NLDS playoffs. Back then, there were 880 APs that comprised the Wi-Fi 4 network; the upgrade to Wi-Fi 6 bumped that total closer to 1,100 APs, Esquibel said. The Dodgers installed 9100 series APs from Cisco in most of the same locations, reusing the cabling and conduits in the process. The Dodgers also replaced network switches (Cisco again, and its 9300 switching line) to handle greater throughput and the increased processing capacity, Esquibel added.

On the cellular side, Esquibel said carriers are adding 5G gear to the stadium, with AT&T having the most extensive deployment right now. Customers of AT&T and Verizon will also be able to be switched over to the Wi-Fi network when entering the park.

The upgrades to its wireless infrastructure also set the stage for some new capabilities coming down the pike. The combo of Wi-Fi 6 and 5G services will help the Dodgers deliver 4k and 8k video formats; it will also help as professional sports move toward “probability gaming,” i.e., online sports betting. Esquibel credits partners Cisco, AmpThink, Horizon Communications and MLB with building a powerful solution to enable these emerging services and capabilities.

Bench seating also got under-seat APs

There were other elements to the Dodgers’ 2020 tech stack refresh as well. Inside the stadium, they reworked the outfield to create a centerfield plaza with left- and right-field pavilions, with cut-outs and walkways above the pavilions plus more APs than last year to accommodate more seated and standing spectators. Esquibel said the team has also replaced its point-of-sale system, and has added Appetize, a cloud-based POS concessions app, as well as ParkHub to keep closer tabs on the Dodgers’ parking lots.

While the Wi-Fi 6 construction is complete, advance testing and fine-tuning are on indefinite hold. As of early June, Esquibel and his Dodger colleagues were sheltering in place and had been since mid-March.

“The pandemic has slowed down testing,” he said, nothing that the stadium needs capacity crowds to gauge how well the new networks are engineered and where antennas need adjusting. And it’s clear that contemplating the first post-pandemic home game brings out Esquibel’s fan boy, broadband wireless notwithstanding.

“I want to smell the grass and be with the crowd,” Esquibel said. “Like everyone else, I just want to see some baseball.”
