NORMAN, Okla. -- After Baylor followed two perfect months with two successive losses, coach Scott Drew was glad to see his star player back on his game.
Perry Jones III had 21 points and tied his season-high with 12 rebounds, leading the sixth-ranked Bears to a 77-65 victory against Oklahoma on Tuesday night.
It was Jones' highest scoring output in 11 games, helping Baylor (18-2, 5-2 Big 12) bounce back after back-to-back losses to conference leaders Kansas and Missouri, both also Top 10 teams.

"Welcome back, Perry Jones," Drew said. "After he tweaked that ankle in Kansas, for a game-and-a-half I think that affected him. He had two good practices and mentally got right and physically has gotten better.
"He's back to playing how he's capable of playing."
Pierre Jackson added 16 points and seven assists, Quincy Acy had 13 points and three blocks for the Bears, who shot 54 percent -- their fourth time in the past five games to hit at least half of their shots.
They also went 9 for 18 from behind the arc, after coming in as the Big 12's best 3-point shooting team at 41 percent.
Steven Pledger led Oklahoma (12-7, 2-5) with 17 points, and Romero Osby had 16 points and 11 rebounds.
The Bears led throughout but needed a strong finish to put away the Sooners, who were within 62-60 in the final five minutes.
"We got a little sloppy on defense and started letting them get a couple easy, open looks. We got a couple offensive rebounds and easy putbacks and really tied down on defense and started defending and rebounding," Acy said.
"That's going to be the key for us to win."
It was only the second victory in 18 tries for the Bears at the Lloyd Noble Center in a series that was heavily lopsided in the Sooners' favor until recent years.
Oklahoma had won 30 consecutive games in the series from 1978 to 2009 before Baylor won three in a row. The Sooners then won at home and knocked the Bears out of the Big 12 tournament last season to regain the upper hand.
Jones helped his team pull ahead down the stretch in this one, putting back Jackson's miss after Oklahoma had gotten within two points. Jackson's three-point play on the next possession made it 67-60 with 3:28 to play.
Jones added another basket from the right block and then two free throws in the final minute.
"We're a step away," Pledger said. "I feel like we've just got to do something one more. We've just got to make that one more extra step, get that one extra rebound, box out that one time harder. We're just one more step away from everything".
The Bears eased out to a 24-14 lead after Anthony Jones' left-hander inside with 10:20 left in the first half.
Oklahoma managed to chip away, cutting the deficit in half before intermission and then getting the crowd standing when Cameron Clark and Pledger connected on consecutive jumpers to pull the Sooners within 37-36 in the first 2 minutes of the second half.
Osby fought through Anthony Jones for a two-handed slam to get the Sooners back within one again following a jumper by Perry Jones, but then the Bears began to distance themselves.
Brady Heslip hit two 3-pointers and Jackson added another during a 15-3 run, and Acy's right-handed dunk on a fast break put Baylor up 54-41.
Another dunk by Osby sparked a string of eight consecutive Sooners points, with Carl Blair's fast-break layup trimming the deficit to 56-52 at the midway point of the second half. Sam Grooms hit consecutive jumpers before Clark hit from the right side to get the lead down to 62-60 in the final five minutes.
"We've got to figure out ways to get some stops, especially in the second half there," said Sooners coach Lon Kruger, whose team has allowed opponents to shoot at least 50 percent in four of five conference losses. "With all due respect, Baylor's very, very good but we still have to figure out a way to get some stops and get into bodies a little bit more (to stop) a couple big offensive rebounds there at critical times.
"I know our guys will keep working. They're not happy with coming close and they're not happy with not getting it all the way done."
