The Wildcats forced six turnovers during a 15-0 run early in the second half of their 82-49 win Saturday over the Redbirds, a victory that sent the defending national champions to a third-round game against Maryland.

Miles Simon had 19 points and Mike Bibby added 19 points and seven assists as Arizona (29-4) reached the round of 16 for the seventh time in the last 11 years. Michael Dickerson added 14 points for the Wildcats.

Dan Muller had 17 points for Illinois State (25-6), which has never advanced past the second round in the NCAA tournament.

First round: SACRAMENTO, Calif. -- Dan Muller wormed inside for a layup with 1.8 seconds left in overtime Thursday night, giving Illinois State an 82-81 victory over Tennessee in a brutal, fast-paced NCAA West Regional duel.

When Tennessee's Vegas Davis missed a desperation heave at the buzzer, Muller turned and bellowed to celebrate the victory in a draining game that seesawed throughout the second half and overtime.

Illinois State, led by Rico Hill's 22 points, LeRoy Watkins' 18 and Steve Hansell's 16, trailed most of the first half but patiently worked back to a 66-57 lead in the second half.
