Washington State (8-12, 1-3 Pac-12) also received two-hit games from Cameron Frost and Justin Harrer and a good relief effort from sophomore Ryan Walker (3-1) who earned the win after allowing two unearned runs, one hit and struck out three in four innings.
The Cougars held Stanford (10-6, 0-1 Pac-12) to just three hits and overcame three errors. Harrer also drove in two runs, scored once and stole a base.
Cougar freshman starter Ryan Ward struck out four and allowed just one hit -- but also walked four -- before exiting with one out in the fourth. Left-handed reliever Trenton Dupre took over for Ward and ended Stanford threats in the fourth and sixth innings to keep the game scoreless.
Washington State went up 2-0 in the seventh but Stanford tied it in the eighth, with both runs coming home on a two-out Cougar error.
In the 10th inning, the Cougs loaded the bases and Cerrillo pulled the first pitch he saw down the right field line to score two. The Cougars tacked on another run. In the bottom half, Walker quickly retired the first two hitters but then made it interesting, as two runners reached with a walk and infield single. Walker got the next batter to fly out to Frost in right for the final out.
Game Two is scheduled for Friday at 6 p.m.
