PROVO, Utah — — Jake Retzlaff threw a 35-yard touchdown pass to Darius Lassiter with 10 seconds left and No. 13 BYU remained undefeated, beating Oklahoma State 38-35 on Friday night.

Retzlaff kept the drive alive with an 8-yard pass to Chase Roberts on fourth-and-7, setting up the decisive play with a 27-yard run up the middle. Lassiter dodged a pair of tacklers before the go-ahead goal for the Cougars (7-0, 4-0 Big 12).

“It’s magical. It’s spiritual,” Retzlaff said. “How can you not be romantic about this game?”

Retzlaff threw for 218 yards and two touchdowns. He also ran for 81 yards and a score.

Lassiter had a career-high 129 yards on six catches, surpassing 100 receiving yards for the second time in three games. LJ Martin ran for a career-high 120 yards and two touchdowns.

They all helped BYU average 7.4 yards per play. The Cougars scored on all four drives in the second half.

“These plays don’t happen by accident,” Retzlaff said. “We did things like that this morning on our walk. We went through those plays, and we ran almost all the plays that we went through in those situations, and the guys did a really good job.

Oklahoma State (3-4, 0-4) lost its fourth straight game despite gaining 421 yards and averaging 6.4 yards per play.

The Cowboys took the lead on Alan Bowman’s 6-yard pass to Brennan Presley with 1:13 left. That meant a limit of 17 turns that lasted almost 8 1/2 minutes.

“It wasn’t typical of what you see from our defense,” BYU coach Kalani Sitake said. “I thought we were freelancing a little bit to try to play a big role.”

Bowman also caught a scoring pass in the second half. Ollie Gordon II ran for 107 yards and two touchdowns and caught a TD pass for Oklahoma State.

Cowboys starting quarterback Garret Rangel left just before halftime with an injury.

BYU trailed at halftime for the second time this season before scoring on consecutive drives in the third quarter to take a 28-21 lead.

The Cougars ran seven consecutive plays, culminating in Martin’s 8-yard rush, to even the score. Then, after Tommy Prassas caught a diving interception at the Oklahoma State 44, BYU took the lead on Keelan Marion’s 34-yard touchdown catch.

The Cowboys got within 28 when Bowman caught a 16-yard pass on a trick play to open the fourth quarter.

BYU made it a 14-7 lead one minute into the second quarter when Tanner Wall returned an interception 51 yards to set up a 1-yard run by Martin one play later.

Gordon had back-to-back touchdowns to put Oklahoma State ahead. He scored on a 17-yard catch, snaking over a defender on his way to the end zone. Then Gordon ran for a two-yard lead with 32 seconds left before halftime.

“You rush the ball a little bit and then the defense opens up and you spread the defense out, which gives you opportunities to do other things,” Oklahoma State coach Mike Gundy said. “Our concepts were excellent, the plan we had was good, it worked and the players executed it.”

THE TAKEAWAY

Oklahoma State: The Cowboys rediscovered their dormant running attack, racking up 269 yards and two touchdowns on the ground. The inability to consistently stop BYU’s offense negated these gains.

BYU: An uncharacteristic flurry of turnovers and sloppy tackles put the Cougars in tough spots for the better part of four quarters. It nearly undercut BYU with a total of 473 yards on offense.
