Carr was far from his best against the stingy defense from Utah State (8-5), matching his career worst with two interceptions. But it was the much-maligned defense that stepped up for a change, giving the Bulldogs (11-1) their first outright conference title since winning the Big West in 1989.
One week after being completely overmatched in a 62-52 loss to San Jose State that dashed any hopes of a BCS bid, Fresno State's defense responded with one of its best performances of the season. The Bulldogs had eight sacks, knocked out freshman quarterback Darrell Garretson and stopped three fourth-down tries.
They didn't allow an offensive score until the fourth quarter, one week after giving up eight touchdowns to David Fales and the Spartans. Fresno State then came up with two late stops to seal the win: Ejiro Ederaine sacked Craig Harrison on fourth-and-7 from the Utah State 41 with 2:47 to play, and Dalen Jones intercepted a pass from Harrison at the Bulldogs 17 with 58 seconds left.
This defensive performance came a week too late to get Fresno State into the Fiesta Bowl. Instead, the Bulldogs are headed to the Las Vegas Bowl, where they could take on Southern California.
The Aggies appear headed to the Poinsettia Bowl.
Carr broke older brother David's single-season school record for touchdown passes (46) and yards passing (4,839) in his final game at Bulldog Stadium. With two more TD passes in the bowl game, Carr will be the fifth quarterback in FBS history to reach 50 in a season. He also needs 125 yards to reach 5,000 on the season.
The Aggies came into the game as the top defense in the conference and played that way, forcing a pair of fumbles in the first half and intercepting Carr twice in the third quarter. The defense even provided the first score for Utah State on Jake Doughty's 86-yard fumble return in the closing seconds of the half.
But an offense missing starting quarterback Chuckie Keaton, running back Joe Hill and tight end D.J. Tialavea to season-ending injuries couldn't take advantage.
The Aggies went three-and-out after Carr's first interception and then were stopped on fourth-and-1 following the second when Joey DeMartino was stuffed for no gain.
Carr then drove the Bulldogs down the field, converting a fourth-and-10 with a 20-yard pass to Isaiah Burse before finding Davante Adams for a 3-yard TD pass to make it 24-7. That was Adams' 23rd TD catch of the season.
After Garretson was knocked out on a helmet-to-helmet hit by Jones early in the fourth quarter, receiver Bruce Natson took a direct snap and ran 10 yards for a score.
Utah State recovered the ensuing onside kick, leading to a field goal by Nick Diaz that made it 24-17 with 9 minutes to play. But the Aggies couldn't get another score.
After a surprisingly sluggish start on offense with just one field goal in the first quarter, Fresno State seemed to take control in the second. Carr threw TD passes to Marcel Jensen and Isaiah Burse, and the defense harassed Garretson with four sacks to build a 17-0 lead.
After Diaz missed a 42-yard field goal for Utah State in the final minute of the half, Carr drove the Bulldogs down to the 11 and in position for another score. But Marteze Waller couldn't handle a pitch from Carr and Doughty returned it for a score that cut Fresno State's lead to 17-7 at halftime.
