AUSTIN, Texas (Ticker) -- James Thomas collected 14 points and 15 rebounds as third-ranked Texas coasted to a 76-45 victory over Texas-Arlington.
It was the second straight double-double and 13th in the last 26 games for Thomas, who had 13 points and 15 boards in Saturday's 81-55 win over Stephen F. Austin.
Despite committing 23 turnovers, the Longhorns never were challenged, improving to 33-2 against in-state opponents under coach Rick Barnes.
The sloppy ballhandling, however, displeased Barnes, whose club blew it open in the second half after managing a 33-25 halftime lead.
"The biggest thing we didn't do tonight was take care of the ball," Barnes said. "We had 12 turnovers at halftime alone and I was upset about it in the locker room. Earlier in the week, we talked about being a better offensive team and taking care of the ball, but we ended up with 23 turnovers, and that is inexcusable."
Texas-Arlington (1-3) shot just 34 percent (18-of-53), turned over the ball 29 times and was outscored in the paint, 46-18.
"Texas dominated the game tonight," UTA coach Eddie McCarter said. "They took us out of the game offensively. Their defense stepped up and made it hard for our guys to pass and get shots off. They wore us down as the game went on."
The Longhorns got Barnes' message, opening the second half with a 15-2 run and extending its lead to 48-27 on Brandon Mouton's jumper with 13:24 to go.
"The difference was our intensity," Thomas said. "The first half, we were sluggish and turned the ball over. Then we had our big guys step up and getting easy buckets."
Royal Ivie, who scored 13 points, capped an 8-0 spurt with a jumper that made it 60-35 with 6:40 remaining. The Longhorns took their biggest lead, 76-42, on Brad Buckman's dunk with 1:42 left.
"I think defense wins national championships, and that is what we want to be," Ivie said. "If our big guys are getting steals and finishing them off, then we know we are playing good defense."
Texas point guard T.J. Ford struggled and was held to five points on 2-of-6 shooting and committed nine turnovers.
"He was getting into trouble tonight because he was penetrating too far into the lane," Barnes said. "He's got to raise up and shoot the ball more. He's making passes that the guys couldn't possibly handle, so he's got to come back out of the paint."
"We tried to get him to make big plays, so we didn't want him to make easy passes," McCarter added. "We had the big men covered and forced him to take shots. I think he was surprised that we wanted to force him to make big plays, but he was pretty effective."
Derrick Obasohan scored 17 points to pace the Mavericks, who dropped to 3-40 all-time against members of the Big 12 Conference. No other player had more than six points for Texas-Arlington.
Texas shot 54.5 percent (18-of-33) in the second half to finish at 51 percent (32-of-63).
The Mavericks did not take advantage of Texas' turnovers, converting them into 14 points. The Longhorns cashed UTA's miscues into 31 points.
