The Tigers led by as many as 10 points in the first half, but MVSU used a 26-8 run for a 45-37 lead going into the break.
MVSU led 56-40 early in the second half, but Grambling State cut it to 73-71 with 2:15 left after a bucket by Ivy Smith Jr. However, that would be as close as the Tigers would get down the stretch.
