Drive down Rochester Avenue toward the ballpark this season and the sign out front reads different than it did last summer. Morongo Field at the Epicenter, it says now, not LoanMart Field. If you've lived in Rancho Cucamonga long enough to remember when the place had no sponsor name at all, this is the third identity the stadium has worn since it opened in 1993. A separate change also altered which franchise plays under the Quakes name.
What changed this spring, and when
In April 2026, Morongo Casino Resort & Spa signed a multi-year deal to become the field's official naming sponsor, replacing LoanMart, which had held the rights since 2013. The rename debuted on April 3 during what the team billed as Morongo Diamond Nights, a game-day celebration where the Morongo Bird Singers performed on the field. Morongo Tribal Chairman Charles Martin summed up the pitch simply: baseball is America's pastime because of its power to bring people together.
The same agreement made Morongo the presenting sponsor of a brand-new team one freeway exit away, the Ontario Tower Buzzers, who opened their inaugural season at ONT Field on April 2 with a ribbon-cutting and a sold-out crowd. That timing is not a coincidence. The two ballparks are now linked by the same casino sponsorship and, as it turns out, by a franchise history that split apart last winter.
The franchise realignment behind the Quakes name
Back in December 2024, Diamond Baseball Holdings announced a three-way realignment across the California League that took effect for the 2026 season. The Quakes organization that had played in Rancho Cucamonga since 1993, the one that won California League titles in 1994, 2015, and 2018, packed up and relocated to a new stadium in Ontario, adopting the Tower Buzzers name and an affiliation with the Los Angeles Dodgers.
In its place, the Inland Empire 66ers franchise moved into the Rancho Cucamonga ballpark and took over the Quakes name, colors, and Single-A affiliation with the Los Angeles Angels. A third team, a relocated Modesto Nuts franchise, slid into the 66ers' old spot in San Bernardino. Diamond Baseball Holdings now owns all three clubs.
So the team wearing Quakes jerseys on Rochester Avenue this season is not the same organization that built those three championship banners. That history now belongs to the club playing as the Tower Buzzers in Ontario. What Rancho Cucamonga kept was the name, the colors, and the ballpark, not the roster lineage.
| Era | Ballpark Name | MLB Affiliate | Team Playing There |
|---|---|---|---|
| 1993-2000 | The Epicenter | San Diego Padres | Quakes |
| 2001-2010 | The Epicenter | Los Angeles Angels | Quakes |
| 2011-2012 | The Epicenter | Los Angeles Dodgers | Quakes |
| 2013-2025 | LoanMart Field | Los Angeles Dodgers | Quakes |
| 2026-present | Morongo Field at the Epicenter | Los Angeles Angels | Quakes (new affiliate, formerly Inland Empire 66ers) |
Read across that table and the pattern is clear. The ballpark name has changed twice since opening. The affiliation has spanned four stretches across three different big-league organizations, Padres, Angels, and Dodgers, with the Angels now back for a second stint. The one constant is the ballpark itself and the Quakes name painted on the outfield wall, which has now outlasted the actual team that made it famous.
What never left
For a resident walking through the gates this year, the disorientation stops fast. The Tommy Lasorda Clubhouse, named for the Dodgers legend in 2013, is still the home clubhouse. Fans still enter off Jack Benny Drive, a nod to the comedian who helped put Rancho Cucamonga on the map decades ago. The Batting Cage Terrace, added when the left field bleachers came out, still lets fans watch players take live batting practice rotations before first pitch.
The two mascots everyone's kids have grown up with, Tremor and Aftershock, are unchanged. So is the food lineup: carne asada fries, tater tot nachos, Mexican street corn, and churro sundaes alongside the standard ballpark rotation of bacon cheeseburgers, Philly cheesesteaks, and bratwursts. The craft beer taps still rotate through Firestone 805, Kona Big Wave, and Elysian Contact Haze IPA next to the usual Coors and Anheuser-Busch options.
None of that is an accident. The stadium sits on city-owned land as part of the Rancho Cucamonga Adult Sports Park, and naming-rights money from sponsors like LoanMart and now Morongo has historically gone back into maintaining a facility the city itself owns and operates. The name on the sign rents space. The city keeps the building.
Catching a game this season
If you haven't been out since the rename, a few practical notes worth knowing before you go:
- Parking runs $6 per vehicle and the lot is fully cashless, so bring a card, not bills.
- ADA parking is marked in Lots A, B, and G, and tailgating is not permitted in any Morongo Field lot.
- The most direct route from the 210 freeway is the Milliken Avenue exit south, then east on Foothill Boulevard, then south on Rochester Avenue. Coming off the 15, exit at Foothill and head west about a mile before turning south on Rochester.
- Pets are welcome on most Wednesdays under the team's designated pet-friendly game schedule, though service animals are always permitted regardless of date.
The full 2026 promotional calendar and gate times are posted on the team's official ballpark guide, which is worth a bookmark if you're planning a weeknight trip with kids or a weekend outing with out-of-town family.
Why the sign matters less than you'd think
The lesson in all of this isn't really about baseball. It's about how identity works in a place like Rancho Cucamonga, where a lot of the fixtures that make a neighborhood feel like home are quietly owned by the city, run by rotating operators, and financed by sponsors whose names change every decade or so. The ballpark has now carried three different marquees and cycled through three different big-league parent clubs across four affiliation stretches, and yet anyone who grew up going to Quakes games would still recognize every inch of it walking through the gates today. That kind of continuity, the sense that a place holds its shape even as the names attached to it shift, is part of what makes long-term residents feel anchored here even when the paperwork behind the scenes gets complicated.
If you're the kind of person who notices details like this about your own neighborhood, whether it's a stadium naming deal, a small business that quietly rebranded, or a street corner that's about to change, you probably already have a good sense of what makes Rancho Cucamonga worth staying in.
