On a February night in Los Angeles, San Diego State University turned a routine midweek game into one of the young 2026 college baseball season’s biggest storylines. The Aztecs went on the road to Jackie Robinson Stadium and stunned No. 1 UCLA 4–3, handing the Bruins just their second loss of the year and picking up a rare, program-defining upset in the process.
Behind three solo home runs, a manufactured insurance run, and a flawless 3 2/3-inning relief outing from right-hander Aidan Russell, San Diego State out-hit the nation’s top-ranked team 10–3 and survived a late UCLA push. The result moved the Aztecs to 5–3, dropped UCLA to 6–2, and marked San Diego State’s first win over a top-five opponent since 2008.
Upsets happen in college baseball, but the context around this one makes it stand out. UCLA entered the game ranked No. 1 by D1Baseball after a dominant 6–1 start that included a sweep of then-No. 7 TCU, outscoring the Horned Frogs 30–8 over three games. Finishing an eight-game season-opening homestand, the Bruins looked every bit like a national title contender.
San Diego State, meanwhile, came in as an underdog from the Mountain West Conference, competing in NCAA Division I and adjusting to a new era under first-year head coach Kevin Vance. The Aztecs have a history of reaching NCAA regionals, but in recent seasons they have been working to reestablish themselves on the national stage and prepare for an anticipated move from the Mountain West to the Pac-12 in baseball. Stealing a win on the road against the top-ranked team in the country checked every box for a statement game.
According to game reports from both schools, this was the Aztecs’ first victory over a top-five opponent since a 15–2 rout of No. 5 San Diego on February 23, 2008, ending an 18-year gap between marquee top-five wins. That historical context makes this 4–3 result more than just an early-season blip; it looks like a potential pivot point for San Diego State University baseball’s trajectory.
The Bruins wasted no time applying pressure in the bottom of the first. UCLA leadoff hitter Dean West worked a walk, stole second, and moved to third on an infield single from star shortstop Roch Cholowsky, one of the headliners in a loaded Bruins lineup. With runners on the corners and no outs, San Diego State starter Alec Belardes was immediately in trouble.
Belardes responded by recording a key strikeout of third baseman Roman Martin, but first baseman Mulivai Levu followed with an RBI groundout that plated West for a 1–0 UCLA lead. For an offense that had just blitzed TCU’s pitching staff, it looked like the first step toward another big night.
Instead, Belardes induced another ground ball to end the inning, limiting the damage to a single run despite the early traffic. That sequence loomed large later. Against a No. 1 team that thrives on putting up crooked numbers, escaping the first with only one run allowed kept San Diego State’s belief intact and prevented UCLA from seizing full control.
San Diego State’s offense began breaking through in the middle innings, powered by a barrage of solo home runs that quieted the Jackie Robinson Stadium crowd and flipped the game.
In the top of the third, catcher Anthony Marnell IV jumped on the first pitch of the inning from UCLA freshman starter Angel Cervantes. He drove it over the right-field fence to tie the game 1–1, providing the Aztecs’ first surge of momentum and signaling they were not intimidated by the Bruins’ top-ranked staff.
One inning later, with two outs in the fourth, outfielder Tyce Peterson turned on a 1–1 offering from reliever Zach Strickland and launched a solo shot to right-center. That blast gave San Diego State its first lead of the night at 2–1.
The power surge continued in the fifth. Junior outfielder Zane Kelly worked the count to 1–2 against Strickland and then belted another solo home run over the right-field wall, the Aztecs’ third straight inning with a solo homer. Suddenly, San Diego State led 3–1 and had taken full advantage of its few mistakes from UCLA’s pitchers.
For a road underdog, the ability to change the game with one swing in three consecutive innings was critical. It allowed the Aztecs to play from ahead, put pressure on UCLA’s offense, and force the Bruins’ pitchers into high-leverage situations earlier than expected.
The long ball grabbed the headlines, but the eventual game-winning run came the old-fashioned way, combining contact hitting and defensive pressure.
In the top of the sixth, infielder Jabin Trosky led off with a single through the right side, chasing Strickland from the game. UCLA turned to reliever Cal Randall, who initially looked poised to slam the door on the rally by recording back-to-back strikeouts.
With two outs, San Diego State appeared on the verge of squandering a leadoff hit. Then came the turning point. On a potential force play at second base, third baseman Roman Martin’s throw pulled the fielder off the bag, allowing Trosky to advance safely instead of ending the inning.
Given new life, the Aztecs took advantage. With two outs and two on, Zach Justice punched an 0–2 pitch between first and second for an RBI single, scoring Trosky and stretching the lead to 4–1. In a game that would eventually be decided by a single run, that combination of hustle, pressure, and timely hitting proved decisive.
Top-ranked UCLA refused to go away quietly. In the bottom of the sixth, Cholowsky opened the inning with a walk and came around to score when Martin ripped a double into the right-center gap. After a walk to Payton Brennan, Aiden Aguayo grounded out to third, but the play was productive, bringing Martin home and cutting the deficit to 4–3.
That two-run frame chased Belardes from the game and shifted the pressure squarely onto the San Diego State bullpen. Belardes finished with 5 1/3 innings pitched, allowing three runs on three hits and three walks while striking out three. His line did not dominate statistically, but he repeatedly worked out of jams and kept UCLA from breaking the game open.
From there, it was Aidan Russell’s stage.
Russell entered in relief with San Diego State clinging to its one-run cushion and delivered exactly what the Aztecs needed. He induced the ground ball that brought in UCLA’s third run, then bounced back to strike out Cashel Dugger and keep the lead intact.
Over the final 3 2/3 innings, Russell retired all 11 batters he faced, striking out five and never allowing the tying run to reach base. In an environment where one mistake could erase a massive program win, he was perfect.
Russell’s most pivotal work came in the eighth inning, when he faced the heart of UCLA’s order with the score still 4–3. The Bruins sent a trio of hitters that included preseason All-Americans like Cholowsky to the plate, poised to do what elite lineups so often do: flip a tight game late.
Instead, Russell authored the defining sequence of the night. He recorded a strikeout, induced a sharp lineout that first baseman Max Farrell snared, and then gave up a deep fly ball to left that Adam Magpoc tracked down at the warning track. The Aztecs walked off the field still ahead by one and nine outs away from one of their biggest wins in years.
In the ninth, Russell closed the door emphatically. He struck out two Bruins and coaxed a routine fly ball to center fielder Jake Jackson, triggering a celebration from the San Diego State dugout as the Aztecs completed the 4–3 upset.
Russell’s final line: 3 2/3 innings, no baserunners, five strikeouts, and 11 straight hitters retired. In any context, that is a lockdown performance. Against the nation’s No. 1 team on the road, in front of a home crowd expecting another UCLA win, it was the kind of outing players and coaches remember for a long time.
Even with Russell’s heroics, the upset does not happen without San Diego State’s depth at the plate. The Aztecs out-hit UCLA 10–3, a striking contrast considering the Bruins had just battered TCU’s staff over the weekend.
UCLA’s offense, which had been rolling through the first two weeks of the season, was held to three total hits and three runs, its lowest run output of the year to that point. For a San Diego State team trying to build its identity under a new head coach, holding a powerhouse lineup in check on its own field offered tangible proof that its pitching and defense can stack up against elite competition.
Official box scores and recaps from both programs highlighted how unusual it was to see UCLA so thoroughly limited at the plate after the TCU sweep. National outlets, including NCAA.com and ESPN, quickly flagged the Aztecs’ win as one of the night’s top stories in college baseball, mentioning it alongside other high-profile upsets.
For San Diego State, this was not just another midweek win; it was a rare breakthrough. The Aztecs had not beaten a top-five opponent since a 15–2 blowout of No. 5 University of San Diego on February 23, 2008, a gap of 18 years between top-five victories.
In the years since that last marquee win, San Diego State has experienced ups and downs, including multiple NCAA regional appearances and seasons of transition. The program’s history includes prominent eras under legendary figures and a strong tradition in the Mountain West, as detailed in their long-running baseball record on resources like Wikipedia and the university’s own archives. Yet cracking through against the very top of the national rankings had remained elusive.
That is why the 4–3 upset at Jackie Robinson Stadium resonates beyond the single game. It came at a time when San Diego State baseball is trying to reassert itself as a perennial postseason program and gear up for a higher-profile conference future. Taking down the No. 1 team on the road signals to recruits, fans, and the broader college baseball community that the Aztecs belong in conversations about programs on the rise.
For athletes and families following college baseball closely, a win like this can be a signal that a program is gaining traction. When a school like San Diego State knocks off No. 1 UCLA, several recruiting takeaways emerge:
As San Diego State continues its road swing with a four-game series at Washington, the UCLA win becomes both a confidence boost and a recruiting talking point. For high school players or transfers looking at Division I options in California and the West Coast, SDSU’s ability to compete with and beat national powers is a meaningful data point.

Upsets of No. 1 teams often ripple through the national picture. UCLA’s loss to San Diego State came on a night when other national contenders were also tested, and national outlets quickly framed it as part of an early-season shake-up across Division I baseball. As NCAA.com noted, both UCLA and LSU, the top two teams in certain polls, fell on the same Tuesday, reinforcing how volatile early-season rankings can be.
For San Diego State, that broader volatility works in its favor. When a non-Power conference team can walk into a No. 1 team’s park and leave with a win, it underlines how talent is distributed across the country and how opportunities exist outside the most famous powerhouse brands.
Recruits and their families watching this result should see it as evidence that impactful college baseball careers can be built at a range of programs. Rankings fluctuate, but player development, opportunity, and coaching stability matter just as much over a four-year window.
