USC (27-20-1, 13-11) scored six in the second all with two outs. A single, walk and hit batter forced in the first run, then three straight singles by Bryce Grudzielanek, Carson Wells and Johnny Olmstead plated five more.
Anson Aroz hit an RBI double to get Oregon (31-16, 14-10 Pac-12) on the board in the top of the fourth.
Turner Spoljaric hit a batter then allowed three straight singles and a double, all with two outs, to make it 10-1. Spoljaric allowed four runs on five hits, a walk and hit batter over 2.0 innings.
Drew Cowley and Sabin Ceballos hit back-to-back home runs in the fifth.
USC added a run in the sixth and Oregon got it back in the seventh.
Five Trojans pitchers combined to allow four runs, three earned, on 10 hits and six walks with four strikeouts.
