AUSTIN, Texas -- Jordan Hamilton broke out of a two-game shooting slump with 20 points and No. 5 Texas rebounded from its first loss in a month with a 76-53 rout of Iowa State on Tuesday night.Tristan Thompson shook off an early flub when he tipped the ball into the wrong basket to finish with 17 points and 14 rebounds for the Longhorns (24-4, 12-1 Big 12). Hamilton and Thompson keyed a big Texas run at the start of the second half that put the game away. Texas had won 11 straight to grab first place in the Big 12 before losing at Nebraska last weekend. The Longhorns sent Iowa State (14-14, 1-12) to its 10th straight loss. Diante Garrett scored 16 points to lead the Cyclones. Hamilton, a contender for Big 12 player of the year, had missed 22 of his previous 26 shots coming into the game and the Longhorns as a team played early like they were still a bit hung over from the loss at Nebraska. Hamilton missed his first three shots, Iowa State grabbed an early lead and Thompson's wrong-basket bucket drew a loud grown from the home crowd. Hamilton made four of his next five shots and scored eight points in 15-6 Texas run. Gary Johnson made his first 3-pointer of the season -- and second of his career -- and Hamilton converted a four-point play that put Texas up 33-23. Texas led 35-26 at halftime. The Longhorns effectively put the game away in the opening minutes of the second. Johnson opened the half with another long jumper and Thompson scored five straight points. The Longhorns led 46-33 before Hamilton made consecutive 3-pointers in a 30-second span that pushed the Texas lead to 19 and the rout was on. Hamilton finished 7 of 14 from the field, including 3 of 4 on 3-pointers. Johnson finished with 14 points and 12 rebounds. The Cyclones, who had lost nine times by six points or less, couldn't keep this one close. When the Longhorns' Matt Hill made a layup with 8:34 to play, Texas led 71-42. The Cyclones were 6 of 24 on 3-pointers. The win keeps Texas' one-game lead over Kansas on top of the Big 12 standings with three regular-season games left to play at Colorado, at home against Kansas State and at Baylor. Iowa State, which has lost seven straight to Texas, played its third consecutive game without senior forward Jamie Vanderbeken, who has a sprained left ankle. Before the game, Texas coach Rick Barnes suspended reserve forward Alexis Wangmene indefinitely for an unspecified violation of team rules. Wangmene, who played in every game before Tuesday night and averaged 2.4 points, was on the bench in street clothes.
