Top 25 football roundup: Backup QB Matt Fink leads USC past No. 10 Utah 30-23

Michael Pittman Jr. caught 10 passes for a career-high 232 yards and a touchdown from backup quarterback Matt Fink, who passed for 351 yards in Southern California’s 30-23 victory over No. 10 Utah on Friday night in Los Angeles.

Fink, a junior who nearly transferred last spring, went 21 of 30 with three touchdown passes for USC (3-1, 2-0 Pac-12) after taking over when freshman Kedon Slovis left with an undisclosed injury on the second play of the game. Fink mostly looked sharp as the third quarterback to play important snaps in four games for the Trojans, who lost starter J.T. Daniels to a season-ending knee injury in their opener.

Tyler Vaughns, Amon-Ra St. Brown and Pittman all caught TD passes from Fink, while Pittman had the fifth-biggest receiving yardage game in USC history. His remarkable 42-yard catch in the fourth quarter eventually led to a 4-yard TD run by Markese Stepp, who celebrated by handing the ball to Reggie Bush, the Trojans great attending the game as a broadcaster despite his NCAA-mandated disassociation from his school.

Devontae Henry-Cole rushed for an early touchdown and Cole Fotheringham caught a TD pass for the Utes (3-1, 0-1), who struggled after star running back Zack Moss left in the first half with an apparent shoulder injury. Utah still has never won at the 96-year-old Coliseum.

Tyler Huntley passed for 210 yards and ran for 60 more, but Utah committed 16 penalties for 120 yards and struggled to get key defensive stops against a green Trojans quarterback.

(20) Boise State 30, Air Force 19: Hank Bachmeier threw for 263 yards and two touchdowns, Robert Mahone rushed for a pair of scores in the fourth quarter, and the Broncos (4-0, 1-0 Mountain West) pulled away from the Falcons (2-1, 0-1) in the second half in Boise.

Bachmeier’s arm made up for a Broncos running game that was ineffective until the fourth quarter. He hit CT Thomas on a 36-yard touchdown pass in the first half while getting crunched by a defender, and added a 28-yard TD toss to tight end John Bates late in the third quarter to give the Broncos a 17-13 lead.

Mahone added a pair of 10-yard TD runs in the fourth as the Broncos won their 20th straight conference opener.

Bachmeier completed 19 of 26 passes in another impressive performance by the freshman in just his fourth start.

Air Force quarterback Donald Hammond III had an 8-yard touchdown run in the first half and threw a 31-yard TD to Geraud Sanders late in the fourth quarter. Taven Birdow led Air Force with 67 yards rushing, but the second-best rushing attack in the country was held to 242 yards, more than 100 yards under its season average.
