Arizona (7-0) needed to shake out the cobwebs after the holiday break and had to rally from a sluggish start with a big run to end the first half. The Wildcats again were flat to open the second half, but had an even bigger run in them, hitting 11 straight shots during an 18-2 stretch that put the game out of reach.
Arizona shot 56 percent and made 10 of 17 from 3-point range to extend its home-winning streak to 25 games.
Gardner-Webb (3-4) made the game close with a strong start to the second half before wilting under Arizona's athleticism.
Tyler Strange and Tyrell Nelson each had 15 points to lead the Bulldogs.
No. 5 LOUISVILLE 64, No. 14 OHIO STATE 55
LOUISVILLE, Ky. (AP) - Terry Rozier made clutch jumpers down the stretch, including a big 3-pointer with 46 seconds remaining, to help No. 5 Louisville survive No. 14 Ohio State 64-55 Tuesday night in the ACC/Big Ten Challenge.
The Cardinals (6-0) were in danger of blowing a 17-point halftime lead before Rozier made three straight baskets in the final minutes including the key shot from behind the arc to provide a 59-53 lead.
Anas Mahmoud and Montrezl Harrell each added a free throw before Rozier made a steal with 16 seconds left and hit a foul shot to finish with 11 points.
Wayne Blackshear's two free throws with five seconds left sealed Louisville's win. He finished with 22 points including four 3-pointers.
D'Angelo Russell scored 17 points for Ohio State (5-1), which still had chances to win despite shooting 30 percent.
No. 6 TEXAS 63, TEXAS-ARLINGTON 53
Texas, which beat defending national champion Connecticut on Saturday, struggled for long stretches and often got sloppy against the Mavericks, who lost by 48 to Kentucky last week.
Jonathan Holmes added nine points and 16 rebounds for Texas, which improved to 7-0 for the first time since the 2009-2010 team won its first 17 and rose to No. 1 in the country.
Holmes also had three blocks as Texas tied the school record of 13. Turner was 2 of 9 from the floor but was 14 of 17 shooting free throws.
Greg Gainey scored nine points to lead Texas-Arlington (3-4), which has lost three in a row.

This was the first game between the two schools

Miami, which has never previously been ranked so high so early in a season, improved to 8-0. The Illini fell to 6-1 with their earliest loss in the past four years.
No. 17 MICHIGAN 68, SYRACUSE 65
Albrecht's shot broke a 63-63 tie after Syracuse (5-2) had rallied from a 10-point second-half deficit. Michigan led 66-65 after Michael Gbinije scored inside for the Orange, and Derrick Walton missed the front and of a one-and-one for the Wolverines. But Syracuse freshman Chris McCullough threw the ball out of bounds with 15 seconds remaining.
Caris LeVert missed the front end of another one-and-one, but the Orange turned the ball over again. This time it was Kaleb Joseph - another freshman - who lost the ball in the frontcourt.
