PASADENA — Rose Bowl sections 21 and 22 were filled with members of the Agoura community as another unlikely character in an unlikely season for UCLA left his imprint Saturday night at the Rose Bowl.
A special section dedicated to senior quarterback Ty Dieffenbach, 50-100 members from his hometown of Agoura, descended upon Pasadena and watched the face of its football community shine under the glittering lights of Pasadena.
UCLA committed 10 penalties for 102 yards, and Dieffenbach led UCLA through the fray to beat Wisconsin 17-7 in front of 36,045 fans.
Dieffenbach shared the impact of the fans who traveled up from Ventura County to watch him complete 22 of 33 passes for 264 yards, with his Agoura coach Dustin Croick in attendance with his children and the various high school players and youth athletes who came to view Dieffenbach’s first win as a starter for UCLA.
“For me it’s more about them,” Dieffenbach said. “Just being an inspiration to those guys and showing guys from our high school that they can go play ball at the highest level. It’s awesome to see them, I love them, and I appreciate them all for coming out.”
Chants of UC! LA! rumbled across the Rose Bowl on Saturday evening against Wisconsin on a muggy afternoon in Pasadena. The collective buy-in from those who sit on the USC/UCLA fence could be swinging more blue.
It was far from pretty. UCLA (6-0, 4-0 Big Ten) struggled to run the ball until the fourth quarter after pounding Oregon for 140 yards in Eugene last Saturday. The Bruins ran for 120 yards against Wisconsin.
There was nothing glittery about Dieffenbach’s play. It was simple execution and playing with steady control.
Dieffenbach prepared each week like he was going to start after two seasons at Pitt and one at Cal Poly. He went into the starting role left by Nico Iamaleava, who injured his knee, and kept UCLA on its rising track to its first 6-0 start since being led by Chip Kelly in 2022.
His short yardage passes to Semaj Morgan, Aidan Mizell and Wayne Knight, 3 to 7 yards at a time, were just as effective as the deep shots he took downfield to Brian Rowe Jr. and Landon Ellis.
And when UCLA needed a big play, Dieffenbach delivered in its most crucial moment during the opening of the fourth quarter. The Bruins faced first-and-18 from their 3-yard line, and Dieffenbach flung a pass 28 yards to an open Ellis.
UCLA’s drive was punctuated by another Dieffenbach throw to Morgan for 33 yards, with 15 yards added, and an ejection to Wisconsin safety Matt Jung after being called for targeting and creating helmet-to-helmet contact. Anthony Woods ran for a 3-yard touchdown, and UCLA eventually put Wisconsin away.
Dieffenbach kept the game simple, orchestrated the offense, but was capable of making a big play when UCLA hit a snag.
“His pre-snap process was phenomenal,” UCLA coach Bob Chesney said. “His ability to see pictures and to understand tendencies and confirm them right before the snap is what leads him to understand where the voids in the zone will live and then deliver the ball to the proper shoulder away from coverage. Those are all things he did a phenomenal job of. You just watch how confident he got rid of it and his belief in himself and his receivers stood out.”
Mistakes were overcome by UCLA’s defense led by linebacker Sammy Omosigho. Although UCLA didn’t force a turnover for the first time in 2026, it did snuff out a troublesome foe, Wisconsin quarterback Colton Joseph, who haunted Chesney and defensive coordinator Colin Hitschler last season at James Madison.
Joseph last season completed 12 of 13 passes for 203 yards and three touchdowns in the first half last season for Old Dominion against James Madison. A season later, Joseph was held to 6 of 16 passing for 66 yards.
Dieffenbach is the latest to rise into a leading man on a roster full of players who have risen to new heights under Chesney. And now the victory has UCLA eyeing its first top-10 ranking as the only team in the Big Ten Conference and SEC to remain undefeated.
“There’s a lot of guys on this team who feel like they have a lot to prove, whether they were here last year or guys that struggled transferring in,” Ellis said. “Guys like Ty who came from an FCS program, these guys have a lot to prove. So to be able to put on (a performance) on a stage like this, there’s nothing like it. It’s awesome.
