USC let Stanford shoot 52.7% from the field Saturday, but survived on timely second-half stops in a 93-79 win at Galen Center that completed a home sweep of the Bay Area schools.
Guard Boogie Ellis had 22 points with five rebounds, four assists and three steals while freshman Isaiah Collier scored 18 of his 26 points during the second half to help the Trojans (8-7, 2-2 Pac-12) hold off the Cardinal, which erased a 10-point deficit in the second half but never pulled ahead.
Forward Kobe Johnson had 21 points on nine-of-18 shooting after breaking out of his month-long shooting slump against California on Wednesday when he made five of his six shots in the second half.
