STILLWATER, Okla. -- Behind a complete game from senior Brad Propst, Oklahoma State knocked off No. 4 Texas, 3-1, Saturday afternoon at Allie P. Reynolds Stadium to even the series at a game apiece heading into Sunday's finale.

With the win, the Cowboys snapped a three-game losing skid in Big 12 Conference play as they improved to 2-3 in the league and 17-6 overall. The loss was the first of the year for Texas in conference play as the Longhorns fell to 4-1 and 17-6 overall.

Propst was magnificent on the mound as the right-hander scattered seven hits and kept UT off the scoreboard until the ninth inning to improve to 4-1 on the season. In tossing the second complete game of his career, the Amarillo, Texas native recorded six strikeouts and did not issue a walk in a 116-pitch effort.

After being shut out in 15 innings in the series opener, OSU got on the scoreboard early in Saturday's contest.

Jared Womack led off the bottom of the second inning with a double off UT starter Hoby Milner, and Davis Duren followed with an RBI single to give the Cowboys a 1-0 lead.

OSU clung to the 1-0 lead until the seventh when the Cowboys added a pair of insurance runs.

Luis Uribe got the rally going in the seventh with an infield single. After Devin Shines walked to put Cowboys on first and second with no outs, Hunter Bailey delivered a sacrifice bunt and reached base on the play on an errant throw by UT catcher Jacob Felts, an error that also allowed Uribe to score OSU's second run.

The Cowboys added their second run of the inning on a sacrifice bunt RBI by Gabe Weidenaar to push their lead to 3-0.

After cruising through the first eight innings, Propst got into trouble in the ninth. Brandon Loy led off the frame with an infield single, but then the Cowboys' defense came up big as third baseman Mark Ginther snared a sharp ground ball off the bat of Mark Payton to begin a 5-4-3 double play.

OSU wasn't in the clear yet as Erich Weiss singled with two outs and then promptly stole second base. Lucas Kephart then provided UT's lone run of the game with an RBI single before Propst got Jordan Etier to fly out to left to end the game.

The two teams will battle in the decisive third game of the series Sunday at 1 p.m.
