In the Sooners first four games away from Norman, opponents had averaged 425 total yards and 29.5 points. Baylor compiled similar stats but they were skewed because the Sooners led 53-10 after three quarters.
OU's defense was dominant against one of the nation's highest ranked offenses. Through three quarters, the Sooners held the Bears to 220 yards, 12 first downs and 10 points.
The Sooners' biggest test of the season will be this week in Stillwater. Oklahoma State leads the nation in total offense (552.0 yards a game) and is third in scoring (45.3).
Middle linebacker Austin Box, making his second consecutive start, was playing well before leaving in the second quarter with an apparent ankle injury. Box did not return.
Freshman running back Roy Finch was shaken up early in the fourth quarter when he was involved in a helmet-to-helmet collision with Baylor safety Ahmad Dixon. Finch lowered his pads and ducked his head but crashed into Dixon's helmet. A groggy Finch was on the turf for five minutes before being helped from the field.
In the first half, Finch's 8-yard touchdown run was a highlight reel play. Finch was hit at the 5-yard line but used his arm to maintain his balance and bounced up to bolt into the end zone.
Safety Quinton Carter, who has battled a neck injury for more than a month, left the game with less than five minutes left. Medical officials were checking Carter's left shoulder but it might be a chronic neck injury Carter originally suffered at Missouri.
Earlier this month, Carter said: "My neck hurt like I had a really bad nerve. It's pretty sensitive... It's like a really bad stinger (but worse). I've had bad stingers in the past and this doesn't compare to any of those."
Quarterback Landry Jones also got up slowly after taking a hard hit in the third quarter. Jones finished the drive before coach Bob Stoops inserted backup Drew Allen on the next series.
RONNELL LEWIS SCORES IN START
In his first career start at defensive end Ronnell Lewis intercepted a Robert Griffin pass and returned it 12 yards for a touchdown on the second play of the second half. Tony Jefferson also recorded an interception on the final play of the first half when Griffin attempted a Hail Mary pass into the end zone.
Pryce Macon made his first career start at defensive tackle. A converted defensive end, Macon's first career start was against Texas. Macon has played a reserve role in recent weeks since being moved inside to compensate for a lack of depth at defensive tackle.
