A five-run first inning catapulted the Oklahoma Sooners baseball team to a 7-4 series-clinching win over Kansas Sunday afternoon on Go Mitch Go day at L. Dale Mitchell Park.

James Hitt pitched eight innings frames and the defense turned in some spectacular plays to lead the Sooners

OU (24-20, 9-9 Big 12) sent 10 batters to the plate in the first inning, scoring on RBI singles by shortstop Dakota Harris and second baseman Jackson Nicklaus and a two-run single by third baseman Wallace Clark.   The Sooners added a run on a groundout by left fielder Kendall Pettis in the second inning.

Catcher Diego Muniz, who was presented with the program’s Mitchell Whitaker Award before the game, lined an RBI double into the left center field alley in the third inning to extend Oklahoma’s lead to 7-2.

The Jayhawks (21-23, 6-12 Big 12) scored two runs in the second inning on a home run by third baseman Michael Brooks and two more in the fifth on a groundout and a wild pitch.

OU dropped the series opener against Kansas, 8-2 Friday afternoon, and won Saturday’s matchup, 11-6, on Alumni Day at L. Dale Mitchell Park.
