After USD senior Turner Trofholz (Schuyler, NE) made a pair of free throws with 1:55 left in the game to put the Coyotes up, 82-79, Morningside's Tom Regan hit a jumper at 1:17 to pull the Mustangs to within one.
On the ensuing possession, freshman Mitch Begeman (Sioux Falls), who came off the bench to score a career-high 12 points on 4-of-6 three's, missed the front end of a one and one, but Trofholz picked up the loose ball in the corner and was forced to call a timeout.
