The Golden Grizzlies started hot and led by double digits in the first half, but the Norse had all but buried the psuedo-home team.
And then Oakland flipped a switch.
The Golden Grizzlies went on a 13-0 run, spurred by back-to-back 3-pointers from Jaevin Cumberland and Tray Maddox Jr. and capped by a pair of Cumberland free throws that gave Oakland a 63-61 lead with under 10 seconds to play.
But in a blink of an eye, OU's tournament hopes were gone again.
The Norse (24-8) will face No. 1-seed Wright State Tuesday night at Little Caesars Arena with a trip to the NCAA Tournament on the line. Wright State took care of Wisconsin-Green Bay 66-54 in the first semifinal of the night.
Cumberland had a game-high 27 points on 7-of-14 3-point shooting.
McDonald's game-winning triple gave him 18 on the night.
