Tyshawn Taylor scored a career-high 26 points and Sherron Collins added 22 of his 26 points in the second half as No. 15 Kansas took over first place in the Big 12 with an 87-78 victory Monday night against third-ranked Oklahoma.

Cole Aldrich was able to dominate inside with the Sooners' missing preseason All-American Blake Griffin because of a concussion. He had 15 points and a career-high 20 rebounds as the Jayhawks (23-5, 12-1 Big 12) took control in the race for their fifth straight conference title.

The Sooners (22-3, 11-2) deployed a full-court press to eat away at the Jayhawks' lead that reached 20 midway through the second half, but the rally could only cut the deficit to three in the final 3 minutes.

Willie Warren led the way with 23 points for Oklahoma, which has lost two in a row, including a 73-68 defeat at Texas when Griffin was first sidelined.

Aldrich and Markieff Morris each had two-handed jams in a 15-2 spurt by the Jayhawks, and stretched their lead to 58-38 when the Sooners were called for goaltending on Taylor's layup with 10:38 to play.

After a wild first half, that certainly didn't put the Sooners out of it.

Cade Davis followed Omar Leary's 3-pointer with two of his own to pull Oklahoma within 62-56 with just under 7 minutes to play, and Griffin came out to halfcourt to greet his teammates and pat Juan Pattillo on the back at the next stoppage.

Leary hit another 3 to cut the deficit to 71-68 with 3:36 to play, but Collins answered at the other end and then did it again after Warren's 3 again got the Sooners within three.

Warren was called for an offensive call on Oklahoma's next possession, and Pattillo then missed a right-handed dunk as the Jayhawks extended the lead out to 80-71 when Taylor made up for two missed free throws with a layup. Kansas was able to seal it from the free-throw line after that.

Pattillo finished with 15 points and Taylor Griffin, Blake's older brother, scored 11 for Oklahoma, which had a 19-game home winning streak snapped. Point guard Austin Johnson had the Sooners' opening basket, but used a heat pad on his troublesome back during the game and didn't score again in the final 39 minutes.

The Big 12's biggest game so far this season lacked some of the sizzle after Griffin was ruled out because of a concussion that left him dazed on the sidelines of the loss at Texas on Saturday night. The player of the year contender is the NCAA's leader in rebounding average (13.8) and double-doubles (22) and the Big 12's top scorer with 22 points per game.

But instead of suiting up, Griffin was in a dark sports jacket and jeans. He participated in a pregame team huddle in the tunnel and hugged Aldrich and Collins as he walked out to the court to watch the Sooners warm up. After that, he was merely a cheerleader.

The Sooners seemed fine without him early, thriving on a hot start from long range that included a rare 3-pointer from Taylor Griffin.

Warren added eight straight points, including a pair of 3-pointers, during a 20-2 run as the Sooners charged ahead to a 22-8 lead.

Taylor led the way as the Jayhawks came right back, hitting three 3-pointers and a fast-break layup during a 16-0 surge that put them ahead 24-22. Taylor then hit three free throws and Tyrel Reed sank a 3-pointer from the right corner with the clock running down to send Kansas to a 36-29 halftime lead.
