PROVO, Utah — Jake Retzlaff threw a 35-yard touchdown pass to Darius Lassiter with 10 seconds left and No. 13 BYU remained undefeated, outlasting Oklahoma State 38-35 on Friday night.
Retzlaff kept the drive alive with an 8-yard pass to Chase Roberts on fourth-and-7, and set up the deciding play with a 27-yard run up the middle. Lassiter eluded a pair of tacklers for the go-ahead score 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, topping 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 second-half drives.
''Those plays don't happen by accident,'' Retzlaff said. ''We were doing that stuff in our walk through this morning. We were running through those plays, and we ran almost all of the plays we run through in those situations and the guys did it really well.''
Oklahoma State (3-4, 0-4) lost its fourth straight game despite gaining 421 yards and averaging 6.4 yards per play.
