KANSAS CITY, Mo. (AP) — Oklahoma coach Lon Kruger had every reason to have confidence at the Big 12 tournament.
The Sooners had rolled into the Sprint Center with three straight wins. They'd had by all accounts a solid week of practice. And they were facing on fresh legs a team that had been pushed in the second half by TCU the previous night.
So much for all of that.
Baylor raced out to a 21-point lead early in the second half Thursday night, and then held on after a frantic rally by the No. 17 Sooners for a 78-73 victory and a spot in the semifinals.
"I thought we entered the ball game in the right frame of mind," said Kruger, the Big 12 coach of the year. "I liked our guys' fight to get back into it, and we had a little bit of a look at it. But they deserved it more than we did."
Cameron Clark scored 19 points and Buddy Hield had 15 for the second-seeded Sooners (23-9), who got within 72-68 on Hield's 3-pointer with 1:27 left, and had a chance to get even closer when Royce O'Neale turned it over for Baylor. But a 3-pointer by Jordan Woodard with about a minute left was off the mark, and O'Neal came through with a pair of free throws.
Oklahoma had a couple of open layups on the ensuing possession, but opted to toss it out to Clark for a 3-pointer. He missed it, the Sooners had to foul again and Brady Heslip — one of the best free-throw shooters in the Big 12 — knocked down two more to help the seal the win.
"We just got too comfortable, it feels like," Clark said. "We have to come out aggressive from the start, like we have nothing to lose."
Isaiah Austin scored 18 points for the No. 7 seed Bears (23-10), who became the first lower-seeded team to win in this year's tournament and will play Texas on Friday night.
O'Neal added 12 points and 10 rebounds for the Bears. Kenny Chery finished with 12 points and seven assists, and Heslip also finished with 12 points.
"That's when we're at our best," Chery said, "when we're sharing the ball."
It was the ninth win in 10 games for Baylor, which has gone from NCAA tournament bubble to knocking on the door of the Big 12 title. The Bears are in the semifinals for the fifth time after ending a four-game skid against the Sooners that included a pair of losses this season.
