Tied 6-6 through regulation with Pacific (8-6), Sarah Lizotte drew a penalty shot and Kirsten Bates converted from five meters to hand UCSD a 7-6 edge with 2:43 left in the first overtime. Under two minutes later, Lizotte added her second goal of the game to give the Tritons a two-goal edge heading into the final extra frame.
Natalie Peng made it 9-6 minutes into the second overtime and UCSD held on for the one-goal victory, despite a pair of goals from the Aggies in the final 68 seconds.
Tied 3-3 at half and then 5-5 after the third quarter, Pacific took the lead when Taylor Adair scored with a man-advantage 47 seconds into the final frame. Just over a minute later, UCSD drew a penalty and Bates converted the free shot to pull even at 6-6 with 5:28 remaining.
The afternoon affair wasn't as kind to the Tritons, as Lizotte managed UCSD's lone goal in the opening half. UCD (6-12) took a 6-1 lead into the break and pushed its lead to nine by the end of the third quarter after holding the Tritons scoreless in the second and third frames.
UCSD outscored UCSD 2-1 in the fourth on goals by Rachel Brooks and Peng, but it proved too little too late.
