AUSTIN, Texas (Ticker) -- Sydmill Harris and Brian Boddicker scored 14 points apiece off the bench as eighth-ranked Texas shook off a sluggish start to post an 80-64 victory over Mount St. Mary's in its final non-conference tuneup.
The Longhorns (9-2) held only a 37-30 lead at intermission but took control in the second half, leading by as many as 29 points.
Mount St. Mary's closed to 45-39 on Donte Alexander's two free throws with 15:24 remaining, but Texas put away the game with a 14-0 run, building a 59-39 cushion on Jason Klotz's two free throws with 11:01 left.
Texas, which hosts Iowa State in its Big 12 Conference opener Saturday, has won its six home games this season by an average of 20 points.
The Longhorns have won four straight overall after suffering consecutive defeats to Arizona and Notre Dame last month.
"Being more efficient means taking care of the ball," Harris said. "It's all of matter of playing like we do in practice. We are ready for Big 12 play. We just picked it up on defense. That's the way we should have been playing from the start."
Jamion Christian scored 12 points for Mount St. Mary's (5-4), which had been off its best start since making the jump to Division I in 1988.
Rick Barnes needs just one victory to become the sixth coach to win 100 games for the Longhorns. Barnes recorded his 300th career victory with a 58-50 triumph over Louisiana Tech in the Longhorns' last outing on December 30.
"I wanted to play teams that I thought could win their league," Barnes said. "Playing those teams have been good for us and has helped us out a lot. Hopefully, what we have done so far has prepared us for conference play."
Texas only shot 37 percent (27-of-73) from the field but held a commanding 52-35 rebounding edge and converted 24 turnovers by Mount St. Mary's into 22 points.
James Thomas and Brad Buckman led the Longhorns' effort on the boards with 16 and 13 rebounds, respectively. Buckman also contributed 11 points for his first career double-double.
"I told J.T. (Thomas) before the game that I was gonna get a double-double," Buchman said. "I was concerned about it since I was starting so many games."
Thomas, the Big 12's leading rebounder, has reached double figures in rebounding in 28 of 34 career games. He came in averaging 11.1 boards per game.
The Longhorns turned the ball over 17 times, but held the Mountaineers to under 36 percent shooting (19-of-53). Kiel Butler was the only other player in double figures for Mount St. Mary's with 10 points.
"They stepped up their defense and we could not do anything," Mount St. Mary's coach Jim Phelan said. "They have a nice, strong competitive club. With their defense and their level of intensity, that is the way they win games. They are well-coached and they are gonna be a hard team to beat."
The Mountaineers tied the contest at 27-27 on Charles Cooks' 3-pointer with 4:37 left in the first half, but Buckman's foul shot ignited a 7-0 spurt that gave the Longhorns the lead for good.
Texas scored the first six points of the second half, opening a 43-30 edge on Brandin Mouton's jumper with 17:36 to go.
