Immediately following a doubleheader victory against Sonoma State University on Saturday, the UCSD baseball team took the field Sunday to face the Cossacks for the fourth time that weekend.

The Cossacks defeated the Tritons 7-2. Junior hurler Tim Worthington put in a good performance at Triton Baseball Field to split the four-game California Collegiate Athletic Association series.

The game was tied 1-1 after the first inning, and stayed that way until the third inning when Sonoma State right fielder Ryan Souza smacked a solo home run. It was his fifth home run of the season and it gave the Cossacks a 2-1 lead.

Sonoma State scored five runs off three hits and one UCSD error in the fourth inning. Three runs came on a home run by Cossack center fielder Keian Davis.

Worthington then shut down the Tritons for the rest of the game. He threw seven and two-thirds innings and allowed just seven hits, two runs and two walks. He struck out five. His record improved to 7-1.

Souza and freshman Brandon Burgess each had two hits for the Cossacks on the afternoon.

UCSD senior ace John Beaven took the loss and dropped to 5-3.

Triton first baseman Chad Addison contributed two hits, and designated hitter Jeff Riddle and freshman shortstop Keith Hernandez scored one run each.

UCSD drops to 23-14-1 overall and 18-10 in the CCAA despite maintaining its conference series unbeaten streak. Sonoma State improves to 33-16 overall, 12-12 in conference play.

The Tritons, just three games out of first place, face an intense four-game homestand this weekend against third-ranked conference leader Chico State University.
