NORMAN, Okla. (AP) -- Jason White hit the turf again and again after vicious hits.
The Oklahoma quarterback slowly got up off the ground and trotted to the sideline as a chorus of boos could be heard from the restless crowd.
A season-long run of dominance by the Sooners was finally interrupted by some sloppiness in the second half.
White threw for 307 yards and four touchdowns, and the Sooners' defense didn't allow a touchdown for the third straight week to lift No. 1 Oklahoma to an inconsistent 41-3 win over Baylor on Saturday.
"In the second half, we just didn't come out and play," White said. "That's something we've had trouble with in other games.
"You're up on a team, it's hard to get the guys going. It's definitely something we need to get fixed."
The Sooners (11-0, 7-0 Big 12) clinched the Big 12 South Division title, earning a spot in the Dec. 6 conference championship game for the third time in four years. The win also keeps Oklahoma on track for a berth in the Sugar Bowl, the site of this season's national title game.
There was no celebration after the victory, however, mostly disappointment that Oklahoma didn't build on its 24-point first quarter a week after its flawless 77-0 rout of Texas A&M.
"I like the fact that nobody is jumping up and down in the locker room," Oklahoma coach Bob Stoops said. "We realize that we still have a lot we've got to keep pushing for."
White, the nation's leader in passing efficiency, had all of his touchdown passes in the first half as the Sooners rolled up 260 yards of offense and took a 34-3 lead.
From there, however, Baylor slowed down Oklahoma's vaunted offense with a steady diet of blitzes that appeared to confuse the Sooners.
The Bears' defense, which came in ranked 109th out of 117 Division I-A teams, sacked White five times, knocked him down several more times and held the Sooners to just seven first downs and 104 yards in the second half.
Oklahoma was limited to a season-low 56 yards rushing, largely due to White's sacks.
There were even a sprinkling of boos heard from the crowd of 82,117 early in the third quarter, likely the result of fans not accustomed to seeing such sloppiness from Oklahoma this season.
"I thought for a minute we were going to shut them out in the second half," Baylor coach Guy Morriss said. "We knew we would have to blitz White to get to him. For some reason, I don't know why, it seemed to work today."
White went on to set the school's single-season record for touchdown passes with 36, breaking Josh Heupel's mark of 33 in 1999.
Mark Clayton caught two touchdown passes from White, finishing with six receptions for 112 yards. Clayton broke Antwone Savage's school record for career receiving yards with 2,094 and extended his own marks for touchdown receptions in a season (14) and a career (22).
Brandon Jones added four catches for 79 yards and a touchdown.
Meanwhile, Morriss turned to a lineup of underclassmen, including freshman quarterback Shawn Bell, to add a little spark to the Big 12's worst offense.
The Bears (3-8, 1-6) didn't have much success, though they did a little better than Texas A&M did the week before.
Early in the second quarter, Baylor already had more first downs and yards than the Aggies had in last week's game. The Bears even put together the longest-sustained scoring drive against the Sooners this season, going 66 yards in 18 plays for Kenny Webb's 28-yard field goal with 6:35 left in the first half.
"I thought maybe (Bell) would be nervous, but he wasn't," Morriss said. "He was playing against the No. 1 team in America, so I thought he did pretty well."
Baylor was held to 183 yards, about 100 below its average of 281 per game, and still had as many first downs as punts (10).
Bell finished 16-of-30 for 108 yards with one interception. He played the whole game, and season-long starter Aaron Karas never got in.
"I'm satisfied with any type of start, just to get the chance to see what I can do," Bell said. "It's a learning experience. We'll move on and hopefully one day be in their shoes."
Oklahoma, which has won all 13 meetings against Baylor, is tied with TCU for the nation's longest winning streak at 12 games. The Bears dropped to 0-10-1 all-time against top-ranked teams.
The Sooners have beaten four Big 12 South opponents -- Baylor, Texas A&M, Texas and Oklahoma State -- by a combined score of 235-25.
Oklahoma closes the regular season next Saturday at Texas Tech.
