Andy Morgan added a pair of rebound put backs in the first quarter, the second giving the Mustangs a 23-9 lead. He finished with a team-high 16 points, including 9 of 9 on free throws.
“I think the guys kind of transitioned and saw a little bit better what they were giving us,” Lee said. “Instead of shooting those outside shots, we were taking what they were giving us. I think we were mixing it up a little bit, inside and outside.”
Grand Valley (2-12, 2-7 NAC Stars) tried to get back in the game in the second quarter. Zack Oscar scored to pull the Mustangs within 28-18, but Mathews pulled away for a 38-20 halftime lead.
Jake Vormelker led Grand Valley with 17 points. He scored seven points in the third quarter, but Mathews was able to extend its advantage to 54-31.
