SANTA BARBARA, Calif. (AP) — Grayson Grinsell struck out nine batters over seven scoreless innings to help No. 3 seed Oregon beat host UC Santa Barbara 2-1 Saturday night at the Santa Barbara Regional.

Oregon (39-18) plays the winner between No. 2 seed San Diego State and top-seeded UCSB, which play early in the day, on Sunday.

Grinsell (7-2) gave up three hits and four walks for Oregon. Ryan Featherston a hit, a walk and a run while striking out three over two innings of relief to earn his second save of the season.

Justin Cassella singled and then stole second before he scored on a single up the middle by Carter Garate that gave the Ducks a 1-0 lead in the bottom of the seventh.

Chase Meggers doubled down the line in left to lead off the bottom of the eighth and was replaced by pinch-runner Jack Brooks, who advanced to third on a wild pitch and scored when Drew Smith grounded out to make it 2-0.
