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 Byron Wesley 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. Brandon Ashley had 14 points for Arizona, which made 14 of 24 shots after halftime to win its 35th straight regular-season non-conference game.
Kyle Wiltjer led the Bulldogs with 15 points. Kevin Pangos had six assists, but was held to eight points on 3-of-10 shooting.
