The Cowboys trailed 2-1 in the bottom of the eighth when pinch-hitter Kenny Hansley led off the inning with an infield hit. Shortstop Chris Gutierrez bunted him to second and a balk by Maverick starter Pierce Loveless advanced him to third. Center fielder Lyndsey Simmons knocked Hansley in with a bloop single to left center to tie the game. Third baseman Josh Fields then singled and first baseman John Urick walked to load the bases for Matulich's game-winning base knock.
Oklahoma State improved to 15-8 on the year while UTA fell to 16-13.
Cowboy ace Scott Baker picked up the win in relief to improve to 5-3 on the year. The Shreveport, La., native struck out two and gave up one hit in 1.2 innings of work in his first career relief appearance.
Baker averted a game-tying situation in the ninth when second baseman Chris Taylor led off the stanza with a double to right center. Third baseman Ryan Roberts followed with a line shot to the left side that was stabbed by OSU shortstop Chris Gutierrez who threw to third to get Taylor out. Baker then struck out left fielder Hunter Pence and got center fielder Robby Deevers to foul out to second to end the game.
Designated hitter Dan Dody led UTA offensively with a 3-for-3 day while shortstop Kasey Baker and Taylor chipped in with two hits each.
