LA JOLLA, Calif. -- UC San Diego took on No. 9 Chico State on Friday at RIMAC Arena, where it stunned the Wildcats with the first loss on their once-perfect record in a 71-65 victory.

The Tritons improve to 7-7 overall and 5-2 in California Collegiate Athletic Association (CCAA) play.

Senior guard Daisy Feder scored a game-high 19 points to lead the Tritons. Feder also had game-highs in both rebounds and assists, with nine and five, as well as a steal.

Sophomore forward McKennan Bertsch contributed 12 points, three rebounds and two steals. Senior guard Emily Osga and junior forward Erin Dautremont both scored 11 points and had seven rebounds. Osga also had three assists, two steals and a block.

Leading the way for the Wildcats was senior guard Synchro Bull, who scored 13 points to go along with three rebounds and three assists. Sophomore forward Analise Riezebos also had 13 points in addition to six rebounds, two assists and a block.

Stronger offense in the second half allowed the Tritons to score 13 more points than the Wildcats in the final 20 minutes. Defense also did its part, holding the Wildcats to a 0-for-9 performance in the closing half behind the arc.

UCSD entered into the second half at the wrong end of a 40-33 score but scored three points in the opening minute from Dautremont's free throw nine seconds into the closing half and Bertsch's layup at the 19:05 mark.

After junior forward McKenzie Dalthorp hit a 3-pointer to put the Wildcats up 46-42 with 14:27 remaining, UCSD cut the lead to a point on Feder's 3-pointer.

Three possessions later, Osga drilled a 3-pointer to give the Tritons the lead and made the score 48-46. Dautremont capped off the 8-0 run with a layup, bringing the Tritons to a four-point, 50-46 advantage and the Tritons never allowed CSUC to regain it.

During a stretch midway through the half, Bertsch added six points in a row to the Tritons' score with two layups and a jumper. The jumper ended the run at the 7:02 mark while giving UCSD a 56-50 lead.

CSUC trimmed the lead to as little as three points twice in the closing minutes. However, the lead returned to six points after a free throw by junior guard Megan Perry with 23 seconds remaining, and a pair of free throws by Feder with 14 seconds left.
