The Tritons move to 30-14 overall and 21-9 in CCAA play. The Seawolves are 27-15 and 13-13 in conference competition.
Lipperd, who no-hit the Tritons in the 2011 CCAA Tournament Championship, has recorded six no-hitters in her career and has held UCSD hitless in two of her last three starts against the defending national champions.
UCSD paid some revenge to Lipperd in Friday's opening game, the first time since the team's met in the postseason tournament last season. Charly Swanberg and Caitlin Brown connected with RBI doubles, and Camille Gaito surrendered just five hits and a pair of walks to improve to 19-6.
After Kris Lesovsky singled and Kirsten Willmon walked in the first inning, Swanberg found the gap in left-center for a two-run double to put the Tritons up 2-0. Lesovsky crossed home plate for the 163rd time in her career- a new school record.
She made it 164 in the sixth inning, scoring on Brown's double to left field to give UCSD a 3-0 lead.
Lipperd doubled Gaito in strikeouts, 11 to five, but the UCSD hurler did not give up an extra base hit. Brown and Swanberg's two-baggers, the only extra-base its of the contest, proved to be the difference in the game.
SSU's ace started game two, bouncing back to strikeout seven Trtions and limit UCSD to one baserunner. Brown walked twice in the game.
SSU's Hayley Condon doubled-in Ancia Purdy with two out in the third inning for the game's only score.
Brown walked with one out in the top of the seventh inning and was replaced by speedster Anne Wethe at first. However, Swanberg grounded into a 5-4-3 double play to end the game.
UCSD and SSU will regroup tomorrow for a final doubleheader starting at 11:00 a.m. at Seawolf Field.
