Going to the eighth inning with Thornhill gone and fastball flame thrower John Curtiss on, the Cowboys still had not had a runner reach third base in 16 innings against Texas pitching in the Big 12 Tournament.
They saved it up as Craig McConaughy singled to start the eighth inning only to get picked off first and thrown out at second. Aaron Cornell came on to pinch hit and singled sharply to left field, Saulyer Saxon worked a deep pitch at-bat base on balls, and then Donnie Walton singled in the gap in left center to score Cornell.
That tied the game at 1-1, but the Cowboys were far from through as closer Brendan McCurry warmed up in the left-field bullpen. RBI singles by Tanner Krietemeier and Tim Arakawa scored two more runs for the Cowboys to take a 3-1 lead.
McCurry came on and retired Longhorns C.J. Niñojosa and Collin Shaw on line drive fly outs before Kacy Clemens struck out looking to end the game.
Oklahoma State goes to 43-15 on the season and forced the quick (45 minutes) turnaround second championship game in the bracket. TCU won the earlier game of the day eliminating Baylor and earning the way into Sunday's overall championship game.
Texas scored its lone run on an RBI single by Ben Johnson that scored Shaw in the fifth inning. The Longhorns are now 38-17 and led until the Cowboys three-run eighth inning rally.
