LUBBOCK, Texas (AP) Oklahoma used a nine-run third inning to seal a 12-7 win over Texas Tech on Friday night.

Texas Tech (20-24) took an early 2-0 lead in the bottom of the first. The Red Raiders came back to add four more runs in the sixth, with Doug Thennis hitting a three-run homer.

Oklahoma (27-16-1) recovered from a shaky start in the third, when all but one of its 13 hitters reached based. Texas Tech's Zach Stewart walked four straight at the start of the inning and allowed nine runs on six hits.

Stewart (2-2) took the loss after giving up nine runs in 2 2/3 innings.

Andrew Doyle (6-3) got the win for the Sooners by striking out four. He allowed six runs on 11 hits in 5 1/3 innings of work.

Ryan Mottern pitched 3 2/3 innings without giving up a run or hit and struckout six for the save.
