Washington State 43, Southern California 38: Brock Motum scored 27 points as the visiting Cougars held the last-place Trojans to 14 first-half points and held off a late rally to win the regular-season finale for both.
 
Motum was 12 of 21 shooting for Washington State (15-15, 7-11 Pac-12), which rebounded from a 32-point loss at UCLA on Thursday and will meet Oregon State in the first round of the Pac-12 tournament.

Southern California (6-25, 1-17 Pac-12), which has lost nine straight games and 18 of its last 19, will play UCLA in the Pac-12 tournament.
 
The Trojans used a 14-2 run to cut the Cougars’ lead to three with 35 seconds left, but Greg Allen missed two 3-pointers and Washington State’s Reggie Moore secured the win with two free throws.
 
Maurice Jones scored 11 points for the injury-depleted Trojans, who are down to six scholarship players.

Byron Wesley, who scored a combined 45 points in his last two games, made one of his seven shots and finished with five points against the Cougars.
 
Washington State won despite going the final 9:09 without a field goal.
