Beavers drop opener at WSU — Washington State’s Joe Pistorese allowed Oregon State just four hits in a complete-game effort and the Cougars downed the Beavers 4-1 Friday night in Pullman, Wash. The Cougars (7-3 Pac-12, 16-14 overall) pinned the season’s first loss on OSU ace Ben Wetzler, who slipped to 6-1. Gabe Clark had two hits for the Beavers (9-4, 25-7), including a two-out single to trigger a ninth-inning rally. Logan Ice followed with a double, but Pistorese retired Caleb Hamilton on a ground ball to end the threat.

Ducks roll past UC Riverside — No. 25 Oregon scored four runs in the third inning to break a scoreless tie and that was all Tommy Thorpe would need to lead the Ducks to a 7-2 win over UC Riverside in Eugene on Friday. Tyler Baumgartner hit a three-run double with two outs to give the Ducks (25-10) a 3-0 lead. Kyle Garlick added an RBI single. Thorpe (5-3) allowed one run on two hits while striking out seven in seven innings. Garlick was 3 for 4 with a solo home run.
