Stanford Cardinal, Calif. (AP) Even without point guard Daejon Davis, Stanford just kept rolling, widening the gap from start to finish in beating Washington State Cougars 98-50 on Thursday night.

KZ Okpala scored 22 points, Cormac Ryan hit four 3-pointers and three others reached double figures in scoring for the Cardinal (15-13, 8-8 Pac-12), who snapped a two-game losing streak. Stanford has won six of eight overall.

Davis injured his foot midway through the first half, going scoreless but with four assists in nine minutes. There was no update on his condition afterward.

Ryan and Isaac White each scored 14, Jaiden Delaire added 12 and Bryce Wills had 10 as Stanford extended its winning streak against the Cougars to six.

''I thought our energy level was off the charts,'' Stanford coach Jerod Haase said. ''I loved our energy defensively.''

CJ Elleby scored 14 of his team-high 16 points in the second half for the Cougars (11-17, 4-11), who lost their second straight after winning three of their previous four. Isaiah Wade added 14 points on 6-of-9 shooting. Robert Franks, Jr. added 11.

''We tried to force some things, and we went back to those three areas that have kind of been our Achilles heel: turnovers for easy buckets, missed blockouts for easy buckets, bad shots for easy buckets,'' Cougars coach Ernie Kent said. ''We got a little frustrated there and the game really got away from us fast.''

Washington State, which has not won at Stanford in eight years, made its first shot and then missed eight straight. The Cougars shot 23 percent in the first 20 minutes and just over 30 percent for the game.

Okpala scored 16 of his points in the first half and the Cardinal shot 56 percent from the field, which included 7 of 12 from long range.

''I made the right plays tonight,'' Okpala said. ''We were all locked in with each other. We came out and did what we had to do.''

Stanford used runs of 11-0 and 16-0 to turn the contest into an early blowout. The Cardinal led by 39 points with just over three minutes left in the opening half and settled for a 52-15 lead at intermission.
