Oklahoma starter Mark Roberts, meanwhile, held the Horns to an infield hit while fanning six through four, but, in the fifth, Texas received RBI singles from Carson Kainer, Drew Stubbs and Hunter Harris after Ryan Russ was hit by a pitch and stole second with one out to claim a 3-2 advantage.
In the bottom of the sixth, Oklahoma had Sheldon lead off with a double to left center field and move to third on a sacrifice bunt, but freshman Randy Boone who relieved UT starter Justin Simmons to face the next batter, rolled a pair of groundouts to escape the jam with the Longhorns still in front by one. Texas then built a two-run lead at 4-2 as pinch-hitter Dooley Prince laced an RBI double off the first baseman's shoulder with two outs in the top of the eighth and runners on first and second via a leadoff single by Harris and a walk to Taylor Teagarden.
Now down by a pair, OU's Russell Raley began the bottom of the eighth with a double down the right field line before Ryan Rohlinger singled to place runners on the corner with no outs. From there, Sheldon hit a fielder's choice RBI to make it a 4-3 game before an infield error and a hit batter loaded the bases with one out. UT reliever J. Brent Cox who came on with no outs, then retired the next two Sooner batters he faced on a strikeout and a ground ball to end the threat and keep Texas in the lead.
Clinging to a one-run advantage in the ninth, the Longhorns tacked on a single run to make it a 5-3 game in their favor when Kainer led off with a single, moved to second on a sacrifice and then scored on a Michael Hollimon base hit. Looking to rally again, OU brought the winning run to the plate in the bottom half of the ninth as Blake Hurlbutt led off with an infield single and Jeff Scuderi was hit by a pitch. Following a sacrifice to put runners at second and third with one down, Rohlinger came through with a RBI base hit before a strikeout and an intentional walk to Andrew McGuire loaded the bases. Cox then fanned the next batter he faced on four pitches to end the game, notch his third save and give UT the series win. Earning the win was Simmons, who allowed two runs on five hits while striking out three over 5-1/3 frames to notch his fifth victory of the season.
Headlining the Texas offense were Harris, who tallied three hits to go along with one run scored and one RBI, and Kainer, who turned in a career-best 3-for-4 effort while scoring two runs and driving in another.
The Horns return home to Disch-Falk Field to open a three-game conference series against Oklahoma State on Friday, 6:15 p.m.
