NORMAN, Okla. (AP) — Kyler Murray sat out the Sooners’ first offensive series then came on to pass for career highs of 432 yards and six touchdowns to help No. 6 Oklahoma defeat Baylor 66-33 on Saturday.

Oklahoma coach Lincoln Riley said Murray didn’t set his alarm clock properly on Thursday night, so he was late to practice on Friday, meaning he couldn’t start.

“It’s a policy, something we stick by,” Riley said. “It wasn’t anything egregious, it wasn’t any big issue.”

Austin Kendall opened the game but Murray entered on the second possession and played nearly flawless football. His passing touchdown total tied for second-best in school history behind Baker Mayfield’s seven against Texas Tech in 2016.

“He played good,” Riley said. “He handled the situation before the game well. Didn’t freak out like I’m sure the rest of America did. It was what it was.”

Murray also ran for 45 yards and a score for the Sooners (5-0, 2-0 Big 12).

“A couple times, when they did get some pressure and things weren’t there, you saw a little bit of the juice that he has,” Riley said. “It’s pretty unique.”

Marquise Brown caught five passes for 132 yards and two touchdowns, CeeDee Lamb had 101 yards receiving and Lee Morris caught two touchdown passes for the Sooners.

Charlie Brewer passed for 400 yards and two touchdowns. Denzel Mims had 11 catches for 114 yards and a touchdown and Jalen Hurd added nine catches for 104 yards and had a receiving touchdown and a rushing score for the Bears (3-2, 1-1).

Murray completed 10 of 11 passes for 192 yards and four touchdowns in the first half to help the Sooners take a 28-9 lead. Baylor scored on its first possession of the second half to cut Oklahoma’s lead to 28-16, but Lamb turned a third-down screen pass from Murray into an 86-yard touchdown.

Murray threw a 50-yard touchdown pass to Brown later in the third quarter, then scored on a 1-yard quarterback sneak on an untimed down on the last play of the period to put the Sooners up 49-23.
