But for the first time in the series, the Longhorns actually jumped on the Sooners.
They scored two in the first when first baseman Alex Silver ripped a single to right, scoring third baseman Erich Weiss, and Sooner right fielder Cody Reine errantly threw to third on the play trying to catch Texas left fielder Jonathan Walsh, but instead allowed him to score.
Texas added another in the second when right fielder Mark Payton singled home designated hitter Landon Steinhagen, who doubled earlier in the inning.
Payton made it 4-0 with a solo shot in the fourth.
And it became 5-0 in the sixth after Texas center fielder Tim Maitland beat out a play at first and Steinhagen raced around from second to score.
The Sooners finally got on the board in the bottom of the sixth when center fielder Max White hit a two-run single through the right side, trimming the deficit to 5-2.
That was just moments after shortstop Caleb Bushyhead broke up Longhorns pitcher Parker French's no-hitter.
However, Reine left a pair of runners in scoring position by striking out, or OU could have cut it closer.
Texas got back to work in the seventh.
Two walks and two more hits allowed the Longhorns to add two more and extend the advantage to 7-2.
Catcher Hunter Lockwood, though, put the Sooners back on the board with OU's third two-run homer of the series, smashing a shot over the left center wall to bring OU back within three at 7-4.
But that was as close as the Sooners could get.
The Longhorns added a couple of insurance runs in the ninth, one on an RBI single by second baseman Brooks Marlow, another on a 4-6 fielder's choice, and that concluded the day's scoring.
Lockwood and White each led the Sooners with a pair of RBIs, while Payton went 2-for-5 with three RBIs and a run scored for Texas.
