Washington State upsets No. 15 Baylor 77-71

Klay Thompson scored 20 points, including two key 3-pointers down the stretch, and Washington State held on to upset No. 15 Baylor 77-71 in the semifinals of the Diamond Head Classic on Thursday.

The Cougars (10-1), who nearly squandered a 20-point second-half lead, withstood a furious rally by the Bears for their fifth straight win. Five players reached double figures for Washington State, which advanced to Saturday's championship game against the winner of the Butler-Florida State semifinal.

Thompson, the son of former No. 1 NBA draft pick Mychal Thompson, made a 3 to give Washington State a 66-64 lead with 4:29 left. He hit another 3 with 1:10 to go and made two free throws with 32 seconds left.

LaceDarius Dunn scored 29 points, all but four in the second half, for the Bears (8-2), while Quincy Acy had 16 points and 12 rebounds.

Down by 20 points, the Bears went on a 29-6 run capped by Dunn's off-balance jumper with 6:49 left to give Baylor a 62-61 lead. It was the first time the Bears led since they had an 8-7 advantage in the opening minutes.

Dunn added two free throws giving Baylor a 64-61 lead. That's when the Cougars, behind Thompson's sweet stroke, took over. Thompson was 5 of 8 from the field, and 5 of 6 from beyond the arc.

Faisal Aden scored 13 points for the Cougars, including a 15-foot baseline jumper that gave them the 20-point lead with 14:29 left. Reggie Moore, Brock Motum and DeAngelo Casto all added 12 points.

Baylor missed its first 16 shots from 3-point range. Dunn missed his first 11 before hitting his first 3 with 10:31 left. His 3-pointer drew Baylor to 68-67 with 1:41 left, but the Bears couldn't get any closer.

While the Bears had trouble penetrating Washington State's zone defense, the Cougars patiently picked apart Baylor with sharp outside shooting and inside passing.

Washington State shot 57.1 percent from the field while Baylor shot 36.7 percent, including 4 of 22 from 3-point range.

Freshman Perry Jones III picked up three fouls and sat out the last 7:48 of the first half. He had two points at halftime and finished with 11 points and seven rebounds.
