COLLEGE STATION, Texas (AP) _ Kirkland Rivers scored the winning run on a bases-loaded balk in the bottom of the ninth and Texas A&M came back from seven runs down to beat Missouri 9-8 on Friday night.

Brian Ruggiano, who hit a two-run homer in the seventh, tied the game when he doubled off Missouri reliever Ryan Allen to score Keith McInnerney. Two batters later, Allen's balk brought home the last of seven runs that Texas A&M scored in the final three innings.

Kyle Thebeau (4-2) pitched a perfect eighth and ninth for the Aggies (35-7, 16-3 Big 12) after his team was down as much as 8-1 in the sixth.

Aaron Senne homered for Missouri (29-12, 9-7) and Ryan Lolis had three hits and drove in two runs. Starter Aaron Crow pitched into the seventh but walked two batters and allowed a double to begin the rally.

Nick Tepesch (1-2) took the loss after putting they tying and go-ahead on to start the ninth.
