UT took an early 1-0 lead in the opening frame with Omar Quintanilla's fourth round-tripper of the season. Baylor responded in the home-half of the first when Michael Griffin doubled in Josh Ford and Ross Bennett to put the Bears on top 2-1.
But Texas blew this open in the top of the second. Three Baylor errors, two wild pitches and Dustin Majewski's two-RBI double set the table for a six run onslaught to stake a 7-2 lead. The Horns added a run in the top of the third on Huston Street's sacrifice bunt from that scored Curtis Thigpen.
Simmons helped the Longhorn cause by retiring 13 Baylor batters in a row until the sixth when Texas took advantage of two Bears' errors and an RBI-single from Eric Sultemeier to post a 10-2 advantage.
Both Quintanilla and Sultemeier doubled in the eighth to make it an 11-2 ballgame. Baylor added a run in the bottom of the eighth on David Murphy's solo shot to complete the scoring. Quintanilla and Sultemeier each went 3-for-5 on the day to lead a Texas offense that tallied 11 runs on the afternoon.
Texas hosts UT-Pan American, 6:30 p.m., Tuesday at Disch-Falk Field.
