The Bears' offense found its footing, and Petty rushed for a 5-yard touchdown to cap a five-play, 69-yard drive and give Baylor a lead it wouldn't relinquish.
Oklahoma's offense came up empty again, but Jed Barnett's punt pinned the Bears on their own 7-yard line with 4:13 before half. The Sooners quickly stopped Baylor on third-and-9, but linebacker Eric Striker had lined up offside, giving the Bears a second opportunity.
Nine plays later, Petty rushed for his second touchdown and the Bears took a 12-point lead.
On Oklahoma's very next offensive snap, quarterback Blake Bell threw the first of his two interceptions, and Baylor added another touchdown to take a 24-5 lead into the break.
All told, the Sooner offense ran seven plays inside the Baylor 12-yard line before halftime, and got almost nothing to show for it. It converted just one of its eight third-down attempts.
“I don't wanna say we got tired, but I mean, you can tell that stuff took a toll on us,” said sophomore linebacker Frank Shannon. “We kept going back out there, so it showed in our play.
“It was real frustrating, but we're a team so we've just gotta put that behind us.”
After halftime, senior cornerback Aaron Colvin, junior nickelback Julian Wilson and freshman linebacker Jordan Evans — all vital pieces of OU's defense — left the game with injuries.
After Baylor's last touchdown and extra point, Tapper's emotions got the best of him during a skirmish and he punched a Bears player.
“Our guys were really motivated to play and really excited to get here and play,” Mike Stoops said of his players' emotions. “That's just part of the game.
“Again, we just didn't play nearly consistent enough to beat a top-ranked team like this.”
