Baker’s grand slam lifts Oklahoma past Wash. St.

NORMAN, Okla. — Aaron Baker’s first career grand slam highlighted a five-run seventh inning, and Oklahoma beat Washington State 7-2 on Sunday in the NCAA tournament.

J.T. Wise’s infield single off reliever Connor Lambert gave the Sooners (43-19) a 3-2 lead. Adam Conley replaced Lambert, and Baker sent Conley’s only pitch over the right-field wall.

Oklahoma went on to bat around for the 23rd time this season.

Washington State (32-25) managed only five hits off Oklahoma starter Garrett Richards (9-4), a junior right-hander who threw his first career complete game and struck out 10, one shy of his career high.

David Stilley (3-3), a redshirt freshman coming off elbow surgery, gave up six hits and struck out four in six-plus innings. It was the left-hander’s second-longest outing of the season.
