ARLINGTON, Texas -- Cael Brockmeyer hit a go-ahead sacrifice fly in the 10th inning and Cal State Bakersfield defeated the University of Texas-Arlington, 6-5, on Sunday.

The victory gives CSUB (21-11 overall, 6-3 in Western Athletic Conference) a 2-games-to-1 series victory and puts the Roadrunners in a tie for first place with the Mavericks (16-14, 6-3 WAC).

Texas-Arlington appeared to tie the game in the 10th inning when, with two outs and Justin Copeland on first base, Brandon Lawrence hit a drive to left-center field. Because the ball became wedged underneath the fence, a ground-rules double was called and Copeland was forced to remain at third base. Roadrunners pitcher Taylor Aikenhead (4-2) then got Darien McLemore to ground out to end the game.

CSUB starter Jonathan Montoya allowed three runs and nine hits over six innings, striking out two and walking none. Aikenhead allowed two runs and six hits in four innings of relief.

Jordie Hein singled with one out in the 10th inning for CSUB and advanced to third on two hit by pitches before scoring on the Brockmeyer sacrifice fly.

Tyler Shryock led the Roadrunners offense, going 4-for-5 with a run and RBI. He has recorded at least four hits in a game three times this season. Brockmeyer went 3-for-4 with two RBIs.

CSUB begins a five-game homestand Tuesday with a 6 p.m. start against No. 23-ranked Cal Poly-San Luis Obispo.
