Northwestern (17-12, 7-10), which lost for the sixth consecutive time to Ohio State, trailed by as many as 13 points before coming all the way back to tie the game at 73 on a dramatic 3-pointer by Alex Marcotullio with 10 seconds to play. John Shurna, who scored 22 points, missed a potential winning 3-pointer as the buzzer sounded.
