BERKELEY - A sweep of visiting USC has the Cal baseball riding a wave of momentum as the Bears head back on the road for four games this week. That stretch begins Tuesday with a trip across the Bay Bridge for a 3 p.m. contest against San Francisco. The game will be streamed live through the USF website as well as TheW.tv and live updates can be found by following Cal Baseball (@Cal_Baseball) on Twitter.

The Bears won a trio of closely contested ballgames to sweep the Trojans with two coming via an Andrew Vaughn walk-off home run. Cal's freshman first baseman earned Collegiate Baseball Newspaper National Player of the Week honors as well as Pac-12 Player of the Week after going 7 for 15 with three home runs, two walk-offs and 12 RBI during a four-game week.

PROJECTED STARTERS
Cal: RHP Rogelio Reyes (2-4, 7.20 ERA)
San Francisco: LHP Sam Granoff (1-3, 5.54 ERA

LAST TIME OUT
Cal continued to demonstrate how tough it is at home with three hard-fought wins over a very evenly matched USC squad. Action started Friday night with a thriller as Andrew Vaughn belted two home runs, the second of which was a walk-off grand slam in the bottom of the ninth inning, and drove in seven runs to help Cal win 13-9.

Another offensive slugfest broke out on Saturday as the Bears scored three runs in the eighth inning to earn a 9-8 victory. Cal hit three more home runs in the victory and Erik Martinez earned his fifth save of the year with a 10-pitch ninth inning.

On Sunday, Cal starter Matt Ladrech set the tone with a gutsy performance as he pitched into the eighth inning and left with the lead. USC rallied to tie the game in the ninth but Vaughn came to the rescue again as the freshman belted a two-run walk-off home run to give the Bears an 8-6 victory. Vaughn ended the weekend with three home runs and 10 RBI.

AWARD TIME
Freshman Andrew Vaughn has earned plenty of recognition for a monster week at the plate as Cal's first baseman was named both a National Player of the Week by Collegiate Baseball Newspaper and Pac-12 Player of the Week. Vaughn went 7 for 15 during a four-game week, hit two walk-off home runs and finished the week with a total of three big flies while driving in 12 runs. The Santa Rosa, Calif. native leads the Pac-12 in home runs with 11, is tied for the conference lead in RBI with 43 and leads all Pac-12 freshmen in batting average, slugging percentage, on-base percentage, hits, RBI, home runs and total bases. 

ON DECK
Tuesday's game at San Francisco kicks off a stretch in which Cal will play seven of its next eight games away from Evans Diamond. The Bears get back into Pac-12 play with a weekend trip to Seattle for three games against Washington before returning to Berkeley for a Tuesday rematch with USF. Cal heads back to the Pacific Northwest from May 5-7 to take on No. 1-ranked Oregon State.
