[1] Wisconsin (34-3) vs. [2] Arizona (34-3)

• A rematch of last year's region final in nearby Anaheim, when the Badgers earned their first Final Four bid under coach Bo Ryan by hanging on for a 64-63 overtime victory. Arizona had a chance to win, inbounding with 2.3 seconds left only a few feet away from their basket, but Nick Johnson didn't get a shot off in time (his jumper missed anyway). Johnson left for the NBA, but the Wildcats will have 6-9 Brandon Ashley, who watched from the bench last year because of a torn knee ligament. Wisconsin saw point guard Traevon Jackson return from a broken foot Thursday; the senior played nine minutes over three spurts, scoring four points.
