AMES, Iowa — Chris Babb scored 17 points and Iowa State beat Texas 77-71 Wednesday night in the Big 12 opener for both teams

Royce White added 14 points and Chris Allen had 13 for the Cyclones (11-3), who won their league opener for the first time in five years.

Sheldon McClellan's layup with 16 seconds left pulled the Longhorns (10-4) within 75-71. But that was as close as they would get, as Allen sealed it from the free-throw line.

Texas star J'Covan Brown finished with 19 points despite missing most of the second half with a right ankle injury. Clint Chapman added a career-high 19 points and 14 rebounds for the Longhorns, who lost just their second Big 12 opener in 14 tries under coach Rick Barnes.
