Then with Minnesota State leading by 13, 38-25, at 1:56, USD used a three-pointer by Little, a lay-up by senior All-American Turner Trofholz (Schuyler, NE) and a three from sophomore Eric Hall (Huron) with four seconds left in the half to cut the lead to five, 38-33, at halftime.
In the second half, the two teams traded runs with MSU going up by 12, 51-39, at 14:21 on another three by Morrow. From then, things went south for the Mavericks as USD scored the next 10 points to start its 26-4 run.
After Minnesota State's Luke Anderson scored two points to put MSU up by four, 53-49, at 9:22, the Coyotes scored the next 10-straight points to post a 59-53 lead at 4:09 on a Trofholz basket in the paint.
Following another Anderson lay-up, USD tacked on another four points on a steal and lay-up by redshirt freshman Jesse Becker (Plymouth, MN) and a pair of Hall free throws at 1:15, which put the Coyotes ahead, 65-55.
