STANFORD, CALIF. - Led by the stellar pitching of sophomore right-hander Ryan Mason and senior reliever Trevor Hildenberger, plus a 12-hit attack, Cal baseball defeated Stanford, 9-5, Monday night at Sunken Diamond to capture the Big Series.
Mason threw 8.0 innings with six hits, four earned runs, three walks and three strikeouts to improve his record to 4-0.
After Stanford had gotten within four on Austin Slater's two-run triple in the bottom of the ninth inning, Hildenberger came in to earn his eighth save by striking out two of the next three batters.
With the win, Cal improves to 18-21 overall and 7-11 in the Pac-12. Stanford drops to 18-19 and 7-11 in league. Cal won its last conference series over the Cardinal at the end of the 2012 season at Sunken Diamond.
The Bears had upped their lead to 9-3 when Mike Reuvekamp scored on a wild pitch in the seventh inning.
Cal tallied a pair of runs in the sixth inning on an RBI single by freshman third baseman Lucas Erceg and a fielder's choice RBI by sophomore outfielder Brian Celsi.
The Bears were able to score twice in fifth inning when Erceg had a two-out single and eventually scored on Robbie Tenerowicz's bases loaded walk. Celsi then scored on a Stanford wild pitch.
The Cardinal got an unearned run in the fourth inning to get within, 4-3, when Danny Diekroeger singled to lead-off the inning, advanced to second base on an errant pick-off attempt by Mason, advanced to third on a Alex Blandino fly ball to center and scored on Slater's ground out to second.
Cal retook the lead, 4-2, in the third inning when senior first baseman Devon Rodriguez knocked a two-run, two-out double through the right-centerfield gap, then scored on a throwing error by Stanford shortstop Drew Jackson on a ball hit by junior DH Brenden Farney.
Stanford took a 2-1 lead in the second inning on a two-out, two-run single by Alex Dunlap off of Mason.
The Bears scored a run in the first inning when freshman outfielder Aaron Knapp led-off with a walk and later scored when Stanford starter Brett Hanewich failed to touch first base on ground ball hit by Farney to first base.
Rodriguez, Erceg, Celsi and senior shortstop Mike Reuvekamp all had two hits apiece for the Bears.
"This was a step forward for us to win two-of-three in a conference series," said Cal coach David Esquer. "Mason threw the best he had all year last weekend versus Washington, and for him to come back with another strong game was big for us."
Cal next hosts San Francisco in a non-conference game Tuesday, April 29 at 6 p.m. at Evans Diamond. The Bears then entertain No. 2 ranked Oregon State, May 2-4, at Evans Diamond.
