(AP) — Tre Demps hit tying 3-pointers at the end of regulation and the first OT, Alex Olah scored 25 and Northwestern beat Michigan 82-78 in double overtime Tuesday night. The Wildcats (15-15, 6-11 Big Ten) wiped out a 12-point deficit in the second half and came away with one wild victory thanks to some huge shots down the stretch by Demps, who finished with 20 points. Olah grabbed 12 rebounds, and Northwestern won for the fifth time in six games. Demps nailed a 3 in transition to make it a three-point game with nine seconds left in the first overtime. The Wolverines played their 11th straight game without the injured Caris LeVert (left foot) and their ninth in a row without Derrick Walton Jr.
