CLEMSON, S.C. (AP) - Connor Costello drove in four runs and starter Thomas Hatch had 10 strikeouts in seven innings to lead Oklahoma State to a 6-0 victory over Nebraska in the NCAA Tournament's Clemson Regional on Friday.
Costello's three hits included a two-run homer, his fourth of the season, in the third inning as the Cowboys (37-20) led 4-0.
Hatch (7-2) didn't need any more than that, holding the Cornhuskers (37-21) to six hits. Trey Cobb worked the final two innings as Oklahoma State moved on to face top-seeded Clemson winner's bracket.
Nebraska will face Western Carolina in an elimination game Saturday at Doug Kingsmore Stadium.
Left fielder Jon Littell and second baseman J.R. Davis each had three hits for the Cowboys.
Nebraska starter Matt Waldron (7-3) gave up eight hits and five runs to take the loss. Waldron ran into trouble right away when Oklahoma State's first five batters reached base in its two-run inning.
