COLLEGE STATION, Texas -- Timely hitting and gutty pitching proved to be the perfect recipe on Tuesday night in Texas-Arlington's stunning 3-2 upset against No. 2 Texas A&M at Olsen Field at Blue Bell Park.

The Mavericks rode five shutout innings from the bullpen to win for the eighth time in the last nine games and improve to 21-12 on the season. The Aggies fell 26-7 and had their four-game winning streak against UTA snapped.

UTA responded to an early deficit with a two-run fourth. Michael Guerra, Preston Morrow and Matt Shortall loaded the bases to open the inning, with a walk and two singles, respectively. Greg McCall drove Guerra home with a single through the right side and Jake Pinchback followed with a sacrifice fly.

The Mavericks tacked on another run in the fifth to break a 2-2 tie. Guerra again was a catalyst with a double down the line in left and scored on Morrow's hit up the middle.

Adam Westbrook made his first start of the season for UTA and battled for four innings. The senior lefty, who had pitched only 12 innings this season, allowed two runs on five hits, and left with a 3-2 lead.

The Mavericks bullpen took it from there. Chase Weaver followed with 2.2 scoreless innings, but needed some help from Chad Nack in the seventh.

The Aggies had two runners on with two outs with Weaver was replaced by Nack, who gave up a hit to load the bases. Nack settled down and left all three stranded after coaxing a ground out to second. He nearly closed out the win, but was lifted after giving up a two-out walk in the ninth.

UT Arlington coach Darin Thomas called on Adam Boydston to close it out, and the lefthander got a pop out from Jacob House to end it.

The Aggies were the fourth Big 12 victim on the schedule for UTA this season. The Mavericks had already beaten Texas, Oklahoma and Baylor.
