Stanford Cardinal, Calif. (AP) Oscar da Silva acknowledged he hasn't always brought the right mindset into a game. He changed that Saturday.

Da Silva scored 21 points and had 10 rebounds, KZ Okpala added 21 points and nine rebounds and Stanford downed Arizona State Sun Devils 85-71 on Saturday to earn its first conference victory.

''He was awesome,'' Stanford coach Jerod Haase said of da Silva. ''He has to be one of the guys who play at a high level. I'd like to see Oscar play like that more consistently.''

Daejon Davis added 13 points and nine assists for the Cardinal (8-8, 1-3 Pac-12 Conference), which has won seven of eight at home against the Sun Devils.

Luguentz Dort scored 16 points for the Sun Devils (11-5, 2-2), who have lost three of five. Rob Edwards had 13 points and Zylan Cheatham had 12 rebounds.

Da Silva scored 14 of his 21 points and had seven of his 10 rebounds in the first half.

The Cardinal scored the first 12 points of the second half, opening a 52-38 advantage. The Sun Devils were held scoreless the first 5:27.

''I found the flow early and my teammates were finding me for a lot of open shots,'' da Silva said. ''When I'm open, I'll shoot.''

Arizona State cut the lead to five points midway through the second half when Kimani Lawrence grabbed an offensive rebound and laid it back in.

''We did everything to start the half that we can't afford to do,'' ASU coach Bobby Hurley said. ''It's a lack of execution. We turned the ball over, in general terms, 19 times, which is way over our season numbers. They played a lot of zone and some man and didn't force us to do much. But going 6 for 17 from the foul line . . . there's a lot of things on offense that you could point to that didn't help us. On the road, you can't play that way.''

That was as close as the Sun Devils came the rest of the way as Stanford went on another run and led by double-digits over the final nine minutes.

''When you don't turn the ball over, good things happen,'' Haase said. ''This past month has been good in terms of practice. Today it carried over. The competitiveness was good and the execution of the game plan was good.''

Stanford went on an early 10-0 run to go up 10-2 less than five minutes before the first half settled into a back-and-forth contest with 11 lead changes. The game was tied on 18 other occasions.

The Cardinal took a 40-38 advantage into halftime.
