Michigan football earned its fourth commitment in three days on Sunday night when East Kentwood defensive tackle Mazi Smith tweeted he would carry Maize and Blue.

The 6-foot-3, 290-pound Grand Rapids is the number 123 prospect in the 2019 category, according to the 247Sports Composite.

Smith has made the 2017 Free Press All-State team in Division I.

He entered last season as No. 7 player in the state, according to the Free Press.

"I'm fast and use my hands well," he said at the time. "I am as good at my hips as it is a lot of aggressiveness that must be used when it comes to my position."
