Jake Retzlaff hit Darius Lassiter with a 35-yard touchdown pass with 10 seconds left Friday night as No. 13 BYU stayed undefeated with a 38-35 Big 12 Conference win over visiting Oklahoma State in Provo, Utah.

The Cougars (7-0, 4-0) trailed 35-31 with 1:13 remaining when Alan Bowman hit Brennan Presley with a 6-yard scoring strike. But Retzlaff led a 75-yard drive, capped by his second touchdown pass of the night.

Retzlaff was 13 of 26 for 218 yards with two interceptions, both quashing possible scoring drives in the first half. LJ Martin rushed 20 times for 120 yards and two touchdowns, while Lassiter bagged six receptions for 129 yards.

Bowman, who relieved injured starter Garrett Rangel late in the first half, was 11 of 19 for 85 yards with an interception. Ollie Gordon gained 107 yards on 16 carries, his first 100-yard game of the year.

The Cowboys (3-4, 0-4) lost their fourth consecutive game.

The pregame storyline concerned Oklahoma State coach Mike Gundy’s decision to bench Bowman, who had been pulled from two of the last three games, in favor of Rangel.

The new starter came in with a 7-0 deficit as BYU ripped down the field to begin the game, with Retzlaff scoring on a 4-yard run just over three minutes into the contest. The Cowboys responded five plays later on Gordon’s 50-yard touchdown run, the longest play of the year against the Cougars.

Martin gave BYU a 14-7 advantage with 14:01 left in the half on a 1-yard run, one play after Tanner Ford intercepted Rangel and returned it 47 yards. But Oklahoma State bounced back as Rangel led a 10-play drive that culminated in his 17-yard touchdown pass to Gordon.

Gordon’s third score of the half, a 2-yard run with 32 seconds remaining, enabled the Cowboys to take a 21-14 advantage to intermission.
