Nick Johnson scored 23 points and freshman Aaron Gordon added 16 points and eight rebounds to lead No. 6 Arizona to a 69-60 victory over San Diego State on Thursday night.
JJ O'Brien and Xavier Thames had 19 points each for the Aztecs (1-1), who had won two of the last three meetings with Arizona (3-0), the loss coming in the final seconds of last year's Diamond Head Classic.
Arizona had a 14-point lead midway through the second half, but San Diego State rallied, closing within four points on Thames' layup with less than 2 minutes remaining.
Gordon then had a soaring dunk off an inbounds pass to put away the Aztecs in the game played at Viejas Arena.
Arizona prevailed despite four players being in foul trouble early in the second half.
