Morgan led all scorers with 16 points and grabbed 12 rebounds as he came back from a minor shoulder injury that forced him out of MSU's game vs. Grand Valley State on Wednesday.
Goran Suton also had a double-double with 15 points and 12 rebounds, Drew Neitzel scored 12 and Marquise Gray scored 10.
Ricky Volcy led the Wildcats in scoring with 14 points, as the team converted 11 of their 17 total field goals from long-range.
"I thought we did some good and some bad," said head coach Tom Izzo. "I thought we rebounded the ball well - especially Raymar (Morgan) and Goran (Suton) in the first half. I thought the defense played well, except for the fouling," he added.
Moving the ball well throughout the game, MSU took the ball inside, outscoring NMU 36-10 in the paint.
The Spartan out rebounded the Wildcats 46-26, including a 30-16 advantage defensively.
Although he started the game, Drew Naymick racked up 4 fouls and only saw nine minutes of playing time.
Raymar Morgan's opening layup at 1:05 into the game gave the Spartans a 2-0 lead, which they would build on and never relinquish. Spartans led by 11 at halftime and by as many as 16 in the second half.
On a negative note, Coach Tom Izzo expressed his disgust with his teams turnover problems.
"We are fouling too much, and we are turning the ball over too much. Some of those turnovers today were somewhat of a ridiculous nature," said Izzo.
The Spartans turned the ball over 21 times, with Travis Walton committing seven alone.
"Some of the turnovers he (Walton) had tonight I am not even worried about though, because they were so ridiculous that he couldn't try to do it (again) if he wanted to," said Izzo.
"The biggest thing I'm concerned about is our focus when we get a little tired. In all honesty, having Drew Neitzel out of there for half the game changed things a bit. He has a little bit of the flu, so I didn't want to risk it. If it was a regular season game I would have played him early, but I wanted to see how our team responded without him in there, in case it happens during the year," Izzo added.
Michigan State has now completed their exhibition tune-ups and will open up the regular season on Wednesday night at the Breslin Center against Brown (7:00 p.m. ET) as part of the Coaches vs. Cancer Classic.
