Down 5-3, Emily Donohoe scored two goals in the final minute and a half to send the game to overtime. She scored her first of two goals to cut USC's lead to 5-4 with 1:37 to play and then hit the tying goal in the waning seconds.
USC had one last chance to win the game in regulation, but the Bruins blocked Kaleigh Gilchrist's shot before the buzzer.
Alys Williams drew first blood in the overtime period, scoring on an exclusion goal to give UCLA the 6-5 lead, which the Bruins held onto for the first overtime. USC, however, scored two unanswered goals to claim a 7-6 lead with under two minutes to play. Mackenzie Barr had a chance to tie with a minute to play but hit the post, and a power play opportunity in the final 10 seconds went for naught when Donohoe's shot missed.
UCLA had jumped out to a 2-1 halftime lead before USC scored three goals in the third period.
UCLA loses for just the second time this season, dropping to 15-2. USC improves to 12-0.
