(Davis) played a lot of minutes at a high, effective rate. Guys left a lot out there tonight. I was proud of him. —Dave Rose

SPOKANE, Wash. — BYU guard Kyle Collinsworth scored 18 of his 20 points Thursday in the second half in helping lead the Cougars to an upset of Gonzaga, 69-68, at The Kennel.

But BYU’s other Kyle — Kyle Davis — helped the Cougars stay in the game while Collinsworth was on the bench with foul trouble for much of the first half.

Davis finished the first half with 10 points, seven rebounds and three blocked shots as BYU trailed by four points, 36-32, at the break. He ended up with a double-double — 12 points and 11 rebounds — to go along with four blocked shots, two steals and only one personal foul in 34 minutes of action.

“(Davis) played a lot of minutes at a high, effective rate,” said coach Dave Rose. “Guys left a lot out there tonight. I was proud of him.”

“He made (Kyle) Wiltjer guard on defense and we took advantage of that,” Collinsworth said of Davis. “He stepped up big for us when we needed it.”

Davis has now scored in double figures 17 times in 18 games for BYU.

NATE’S NIGHT: Senior forward Nate Austin went out in the first half after he got hit in the face and was taken to the locker room.

Austin returned in the second half and helped lift the Cougars to victory, particularly with two blocked shots in the final 30 seconds. His final block came against Wiltjer with two seconds remaining to preserve the victory.

“Nate was really good defensively late in the game,” Rose said.

UNSUNG HERO: Freshman guard Jordan Chatman was summoned into the game with Collinsworth, and other Cougars, in foul trouble.

In 19 minutes, he scored only two points, but Rose said his contributions were huge.

“He hit one shot, but defensively he was really good for us,” Rose said. “Then, as far as our offensive possessions, he really executed our stuff. I was happy to see him come in and get significant minutes in a tight game. Defensively, he really gave us a lift.”

BIG CALL: With 6.6 seconds remaining, Collinsworth rebounded Wiltjer’s missed free throw that could have tied the game. Collinsworth fell straight to the floor and the officials called traveling.

“We didn’t have any timeouts. Luckily, I remembered that,” Collinsworth said of the play. “I jumped up and got it and got my legs taken out from under me. I hit the floor. I held on to (the ball).”

TIP-INS: Austin tied Noah Hartsock for No. 5 in BYU history in career games played at 134. … The Cougars’ record at Gonzaga is 2-3. … BYU hit 12 of 14 shots from the free-throw line.
