Arizona let the opposing team dictate the pace on its home court, struggled defensively in the second half and watched as yet another last-second shot ping-ponged off the rim and the backboard. When the shot finally fell to the floor, the Wildcats walked off with another close victory and another big sigh of relief. Coming off a nail-biting win in its conference opener, No. 3 Arizona escaped with a 60-57 victory over Utah on Saturday after a last-second shot by Utes guard Jarred DuBois bounced twice off the rim and once off the backboard before missing.
