T.J. McConnell scored six of his 12 points in overtime and No. 3 Arizona held on for a 66-63 victory over No. 9 Gonzaga after Gary Bell, Jr. air-balled the first of three missed free throws with 3.3 seconds left on Saturday.

Arizona (8-0) rallied from a poor-shooting first half and a couple of deficits in the second half to force overtime. McConnell, limited in the first half by foul trouble, was assertive in the extra period, leading the Wildcats to their 26th straight home win.

Brandon Ashley had 14 points for Arizona, which has won 35 straight regular-season non-conference games.

Gonzaga (7-1) shot well inside, but went 4 for 17 from 3-point range and had two key turnovers late in overtime.

Bell had a chance to tie the game after being fouled on a 3-pointer, but was well short on his first attempt and clanged away the other two.
