Trevor Larnach, Adley Rutschman and Cadyn Grenier each homered, and the top-ranked Oregon State Beavers scored eight runs in the final three innings for a series-clinching 10-4 win at California on Saturday.
The top four batters in the Beavers' lineup -- the home-run hitting trio plus leadoff man Steven Kwan -- did most of the offensive damage in the Beavers' second of three games in Berkeley. They combined for 10 hits, eight RBIs and seven runs scored.
Kevin Abel (2-0) tossed a scoreless inning in relief of OSU starter Bryce Fehmel to get the win, and Brandon Eisert pitched the final 2 2/3 innings to pick up his second save of the season.
Kwan, who went 3 for 5 at the plate, singled in the top of the fourth to score Jack Anderson for the Beavers' first run. OSU (17-1, 2-0 Pac-12) scored again in the fifth on Larnach's leadoff homer to left-center that tied the game at 2-2.
Cal (12-6, 0-2) briefly took the lead at 3-2 in the sixth when Abel walked in a run that was charged to Fehmel, who allowed three runs on six hits in 5 1/3 innings.
After a 98-minute rain delay in the sixth, the Beavers' offense really came alive in the seventh.
Larnach drew a one-out walk, and then Rutschman homered to left-center to give OSU the lead for good at 4-3.
Grenier's two-run shot came in the eighth, part of a four-run inning as Rutschman and Preston Jones then hit consecutive RBI doubles that came immediately after Larnach's double.
Cal got one back in the bottom of the eighth on a sacrifice fly to make it 8-4, but the Beavers tacked on two more runs in the ninth, helped by a Cal error on a play that might have otherwise ended the inning.
The Golden Bears put on two runners in the bottom of the ninth with a leadoff single and a walk, but Eisert got out of the jam.
Next up: OSU will try to sweep its three-game series at Cal at 1 p.m. Sunday. Beavers coach Pat Casey is set to return to the bench after serving a four-game suspension imposed by the NCAA after Casey made contact with an umpire during the Beavers' 5-3 home loss to Cal State Fullerton on March 9.
