Monte Morris scored 20 points and No. 21 Iowa State took the lead for good in the final minute before holding off Indiana State 73-71 in the opening game of the AdvoCare Invitational at Disney World on Thursday.

Joe Thomas shrugged off a poor shooting performance to put the Cyclones ahead with a 3-pointer with 54 seconds remaining. Nazareth Mitrou-Long made one of two free throws with 7.6 seconds left, and Indiana State’s hope for an upset ended when Brenton Scott’s 3-pointer rimmed out at the buzzer.

Iowa State (4-0) advanced to the tournament semifinals, despite going 5 for 15 from the foul line over the final 10 minutes. The Cyclones trailed for most of the first half before using an 11-0 run to wipe out a nine-point deficit.

Scott led Indiana State (2-2) with 20 points on 7 of 18 shooting, a pair of long 3-pointers that gave the Sycamores leads in the closing minutes.
