If there was any concern about replacing Preston Beck in the heart of UT Arlingtons lineup, J.M. Twichell did everything he could to alleviate it this past weekend.Twichell went 5 for 11 with a double and two triples to power UTAs season-opening sweep of Louisiana Tech. Tonight, he and UTA take their 3-0 record to Austin to face the Texas Longhorns at 6 p.m. at UFCU Disch-Falk Field.He needs to be one of our guys that can drive runs in for us, coach Darin Thomas said. He had a really good weekend.The Longhorns are off to their usual strong start, taking two out of three against Sacramento State. Freshman shortstop C.J. Hinojosa had a great offensive weekend by hitting .545, but he also had three errors in as many games.UTA is no stranger to Disch-Falk Field, having traveled there for all 71 games of the all-time series between the two programs. The Mavericks have only won 17 games against Texas, but they beat the Longhorns 7-5 last season.
