LA JOLLA, Calif. -- Staff ace Tim Shibuya threw another gem and the Tritons banged out 11 hits as top-ranked UC San Diego won both ends of a doubleheader against CCAA opponent Cal State East Bay Saturday at Triton Ballpark. In the first league games of the season for both teams, UCSD took the opener 1-0 and was victorious in the nightcap 10-4.

UCSD has now won six games in a row and improved to 9-1 overall and 2-0 in the CCAA. Cal State East Bay dropped to 2-7 and 0-2. The Tritons have matched their best 10-game start since moving to NCAA Division II in 2001.

In game one, Shibuya, a senior righthander, improved to 3-0 on the year as he went seven scoreless innings, giving up just one hit as he faced the minimum. Shibuya, who became UCSD's all-time wins leader last week, struck out four Pioneer batters and walked two.

Elias Tuma pitched the last two innings, striking out two en route to his second save of the year.

The Pioneers also got a solid effort out of their starter, Bryce Miller (1-2). He went all eight innings and gave up just the one run on three hits. He struck out two and walked three.

UC San Diego plated the lone run of the game in the third inning. With one out, left fielder Aaron Bauman doubled to left-center and advanced to third as East Bay's centerfielder threw the ball back to the infield without anyone awaiting it. Bauman's heads-up baserunning paid off as the next batter, centerfielder Danny Susdorf, also doubled to left-center, scoring Bauman.

Kyle Saul had UCSD's third hit, a two-out triple to centerfield in the first inning.

The Pioneers left six runners on base in the game.

Game two featured much more offense with a combined 21 hits -- 10 by East Bay and 11 by UCSD.

After one full inning the score was tied 2-2. The Pioneers' leadoff batter reached on an error and was doubled home by Andrew Woolfe. The next batter, Nick McManus singled through the right side of the infield to give CSUEB a 2-0 lead.

The Tritons answered right back. With one out, Susdorf singled and stole second. Saul walked and Blake Tagmyer was hit by a pitch to load the bases. First baseman Nick Hom then laced a two-run single past the third baseman down the left field line to tie the game at two.

UCSD would get all the runs it would need to win in the second inning as they plated three to go up 5-2. With the bases juiced, Saul doubled down the left field line to knock in a pair of runs. The eventual game-winning run was scored on a sacrifice fly by Tagmyer that plated catcher Kellen Lee.

The Tritons added a single in the third, fifth and sixth innings and put up two more in the seventh.

The run in the third inning was all Hom, who led off with his first home run as a Triton, a bomb over the fence in left-center. Hom played two years at Fresno State, winning a national championship with the Bulldogs in 2008, before transferring to UCSD in 2010. He played in just 16 games in his first year with the Tritons.

After scoring a run in the sixth, the Pioneers threatened again in the top of the ninth. With the bases full, Bret Gibson was hit by a pitch, scoring Jared Berrier and making the score 10-4 in favor of the Tritons. With two outs, relief Justin Burns came on to get the final out.

UCSD starter Guido Knudson (2-0) took the win, pitching eight innings and giving up three runs (two earned) on 10 hits. He struck out six and walked just one.

Paul Jinkens dropped to 0-3 on the year as he gave up seven runs on seven hits in five innings. He also issued five walks.

Saul finished with four RBI, while Hom was 3 for 4 with a two runs and three RBI.

For the Pioneers, catcher Josh Rush went 3 for 4 with a run and McManus had two hits and a RBI.

East Bay left 12 runners on base and UCSD left 11 in the second game.
