SAN DIEGO >> Nick Johnson scored 18 points, Aaron Gordon added 16 and top-seeded Arizona overcame a shaky start and a late run by Weber State to beat the Wildcats 68-59 in the NCAA tournament’s West Regional on Friday.

Arizona (31-4) fell into an eight-point hole in the opening minutes to give the 16th-seeded Wildcats hope of a monumental upset.

The desert Wildcats tried to squash the dream quickly with two big second-half runs, but Weber State fought its way back from a 21-point deficit to make it close in the second half.

Arizona blocked 12 shots, held Weber State to 30 percent shooting and made 55 percent of its shots to earn a spot in Sunday’s third round against Gonzaga or Oklahoma State.

Davion Berry had 24 points to lead Weber State (19-12) in its first NCAA tournament appearance since 2007.
