COLUMBIA, Mo. -- No. 7 seed Arkansas (38-14) fought off a seventh-inning push by No. 10 seed Kentucky (31-19) to beat the Wildcats 3-1 and secure their first tournament win since 2001.

Kentucky had runners at the corners facing two outs in the top of the seventh when shortstop Katie Reed got caught in a rundown between first and second to end the game.

Freshman pitcher Mary Haff (25-6) was credited with the win in her postseason debut. Haff pitched a complete game, striking out five batters and only allowing one run, a solo homer by Kentucky's Lauren Johnson in the top of the second.

Kentucky pitcher Grace Baalman (12-8) allowed four hits and three runs in six innings with a 2.37 ERA.

Arkansas' go-ahead run came in the bottom of the third after a series of defensive errors by Kentucky.

Razorbacks freshman Hannah McEwen reached base on a left-field single followed by Autumn Buczek getting on base off a fielder's choice. A Kentucky error gave McEwen the unearned run, tying the game 1-1 and advancing Buczek to third. Buczek scored the go-ahead run on a wild pitch, putting Arkansas up 2-1 before Baalman closed out the inning.

UP NEXT: Arkansas faces off against No. 2 seed Georgia in the second game of the Second Round. The first pitch is scheduled for approximately 2:30 pm ET Thursday on SEC Network.
