Las Vegas — BYU kept turning the ball over, and Utah kept scoring.

About the only question left after five first quarter touchdowns by the Utes was how big their Las Vegas Bowl rout would be. Until BYU regained its composure, that is, and made it a game for both teams to remember.

Utah took advantage of a disastrous start by BYU, scoring five first-quarter touchdowns on turnovers — including two interceptions by Tevin Carter — before holding on Saturday to beat the Cougars 35-28.

“We ended up with the win, which is all that matters,” Utah coach Kyle Whittingham said. “It’s the only thing that matters.”

Utah used its string of first quarter turnovers to build a 35-0 lead, then managed to hold on as BYU mounted a comeback that brought the Cougars to within one score with 3:23 left in the game. BYU couldn’t get the ball back, though, losing in Bronco Mendenhall’s last game after 11 years as head coach.

“We did lose the game,” Mendenhall said. “But I’m taking with me a pretty good going away present.”

After the game, BYU said it hired former Cougars running back Kalani Sitake as head coach. Sitake was Oregon State’s assistant head coach and defensive coordinator.

Carter returned one of his picks for a touchdown and another to the 1 as No. 20 Utah romped to a 35-0 first- quarter lead in the first meeting of the two heated rivals outside of the state of Utah. BYU turned the ball over the first five times it had the ball, with freshman quarterback Tanner Mangum throwing three interceptions and fumbling once.

That was all the scoring Utah did, and it nearly cost the Utes the game. Mangum would bring BYU back, throwing two touchdown passes and rushing for another to get the Cougars close.

“Giving up was never an option,” tight end Remington Peck said. “Everybody had the mentality that we would somehow find a way to get back in it.”

Mendenhall’s last game as BYU coach was almost over even before some of the fans settled into their seats, thanks to an opportunistic Utah defense that forced Mangum to fumble on the third play of the game. Midway through the first quarter, the Utes were already up 28-0.

In a statistical quirk, BYU actually outgained Utah offensively (89-69) in the first quarter. But Carter and Dominique Hatfield both scored on interceptions, Joe Williams had two 1-yard touchdown runs, and quarterback Travis Wilson added another TD on a 20-yard run.

“You’re not going to lose a lot of games when you’re plus-5 in the turnover department,” Whittingham said. “We got complacent and that’s on me. Next time we’re up 35-0 hopefully we won’t have the same results.”

Mangum’s shaky start didn’t stop him from throwing for 315 yards in rallying his team. BYU dominated much of the game, but couldn’t quite dig itself out of the big hole.

“I think the game was a little big for him at the beginning, but man he turned around and played a great game,” said end Bronson Kaufusi, who played his last game. “Ultimately he gave us a chance to have the ball at the end.”

Utah (10-3) came in as a 2-point favorite in the first meeting since 2013 of schools that have campuses just 46 miles from each other. But the quick succession of turnovers — Utah scored its first four touchdowns in a span of 3:30 — threatened to turn the game into a rout before BYU settled down.

BYU ended up with 386 yards to 197 for Utah, but the five early turnovers were the key in a game where the Utes didn’t turn the ball over at all.

Mendenhall, who is leaving BYU (9-4) after 11 seasons to coach at Virginia, failed in his try at win No. 100 at the school. Mendenhall, who wanted to coach the bowl game before leaving, finished his BYU career with a 99-43 record.

“I’m not sure I’ve ever been more proud of my team,” Mendenhall said. “They stayed together and unified and battled back and made it a great football game. Our team tried really, really hard all the way to the very end, maybe if we make one more stop it gets interesting.”

Mangum, who earlier this season led the Cougars to last-minute comebacks against Nebraska and Boise State, never had a chance to do the same against the Utes. After bringing them within a touchdown with 3:23 left, he could only watch on the sideline as the Utes picked up two first downs and ran out the clock.

BYU was down largely because of the early mistakes by the freshman, who lost a ball while scrambling on the third play of the game, then threw interceptions on the next three drives. Coming into the game, Mangum had thrown just seven picks all year.

Mangum ended up completing 25 of 56 passes for 315 yards. Wilson was 9 for 16 for 71 yards.

Utah, which at one point in the season was 6-0 and ranked No. 3, had 19 interceptions in the regular season, seventh best in the country. The Utes wasted no time adding to that number with two picks on tipped passes by Carter followed by a 46-yard interception return by Hatfield for a touchdown.

The win before a sellout crowd of 42,213 was the ninth in 10 bowl games for Whittingham as head coach of Utah. The Utes have won 12 of their last 13 bowl games.

New Mexico Bowl

Arizona 45, New Mexico 37: At Albuquerque, N.M., Anu Solomon threw two touchdowns passes and ran for another score to help Arizona hold off pesky New Mexico in the New Mexico Bowl.

Arizona (7-6) and its quick offense overwhelmed the Lobos (7-6) in a game that saw New Mexico surge late after being down as many of 18 points.

Jared Baker ran for 107 yards and three touchdowns, and Cayleb Jones had 182 yards receiving and a touchdown. Linebacker Scooby Wright III, who battled injures all season, came back for the bowl game and had two sacks and 11 solo tackles. After the game, Wright said he will enter the NFL draft.

New Mexico quarterback Lamar Jordan rushed for three touchdowns and threw a 92-yard touchdown pass to Delane Hart-Johnson before leaving the game in the third quarter with a knee injury. Arizona held star running back Jhurell Pressley to 75 yards rushing and no touchdowns.

New Orleans Bowl

Louisiana Tech 47, Arkansas State 28: At New Orleans, Kenneth Dixon had 215 yards from scrimmage and scored four times to become the NCAA’s career touchdowns leader, and Louisiana Tech beat Arkansas State in the New Orleans Bowl..

Dixon caught six passes for 113 yards and touchdowns of 9 and 59 yards. He carried 21 times for 102 yards, including scoring runs of 8 and 4 yards.

He has 87 touchdowns and 522 points, putting him three TDs and 10 points ahead of Navy quarterback Keenan Reynolds, who plays Monday in the Military Bowl.

Jeff Driskel, a transfer from Florida, closed out his college career by passing for 458 yards and three touchdowns for Louisiana Tech (9-4), which had 687 total yards in finishing a second straight season with a bowl victory.

The loss snapped an eight-game winning streak for Arkansas State (9-4), the Sun Belt Conference champion. Taylor Blaise had a 98-yard kickoff return for Arkansas State in the fourth quarter, but by then it was too late to mount a comeback.

Camellia Bowl

Appalachian State 31, Ohio 29: At Montgomery, Alabama, Zach Matics capped a wild Camellia Bowl with a 23-yard field goal on the final play to lift Appalachian State past Ohio.

The Mountaineers (11-2) moved from their own 21 in the final 1:42 after rallying from a 24-7 deficit in the fourth quarter only to lose the lead again. It was their first bowl game since moving up to FBS.

Quarterback Taylor Lamb had a 32-yard scramble then handed off to backup tailback Jalin Moore several times. Moore had a tackle-breaking 15-yarder and a 6-yarder to set up the kick by Matics, who missed two earlier attempts.

A safety and Josiah Yazdani’s 21-yard field goal had given Ohio (8-5) the lead in a game where the Bobcats scored two defensive touchdowns after a sluggish start.

MVP Marcus Cox gained 162 yards on 24 carries for Appalachian State, which set a Sun Belt Conference record for wins in just its second season in FBS.

Cure Bowl

San Jose State 27, Georgia State 16: At Orlando, Florida, Kenny Potter scored on a 42-yard run and threw a 1-yard touchdown pass to Josh Oliver in San Jose State’s comeback victory over Georgia State in the inaugural Cure Bowl.

Austin Lopez kicked a pair of 19-yard field goals, and Tyler Ervin returned a punt 85 yards for a touchdown for the Spartans (6-7). Ervin had 30 carries for 132 yards to become San Jose State’s single-season rushing leader with 1,601. He also set the mark for most all-purpose yards in a season.

San Jose State was one of three teams given bowl berths despite losing records. The Spartans were awarded their postseason spot based on their Academic Progress Rate of 975.

Georgia State’s Nick Arbuckle threw for 208 yards and two touchdowns, including a 19-yard scoring pass to Todd Boyd that gave the Panthers (6-7) a 16-13 lead early in the fourth quarter. Arbuckle also threw a 38-yard touchdown pass to Donovan Harden, and set a Sun Belt Conference record for single-season passing yards with 4,368.
