AMES, Iowa (AP) -- Freshman Avery Bradley scored 24 points, including 16 in the second half, and top-ranked Texas survived its first Big 12 road test of the season by beating Iowa State 90-83 Wednesday night.

Damion James added 23 points and 14 rebounds for the unbeaten Longhorns (16-0, 2-0), who opened the second half with a 16-4 run and never trailed again.

It was the Longhorns' first game as the top-ranked team, and for the second straight game Bradley led the way.

Bradley, who had a career-high 29 points in a win over Colorado on Saturday, shot 10 of 14 from the floor and added six assists, six rebounds and three steals.

Marquis Gilstrap had 20 points and 13 rebounds for Iowa State (11-5, 0-1), which lost its 16th straight to ranked opponents since 2006.
