AMES, Iowa (AP) — While everyone focused on the debut of Michigan's Mitch McGary, it was easy to forget that Iowa State got Melvin Ejim back too.
In a matchup of returning stars, Ejim outshone McGary and led the Cyclones to one of their biggest wins under coach Fred Hoiberg.
Ejim returned after missing two games with a hyperextended knee to score a game-high 22 points and Iowa State beat No. 7 Michigan 77-70 Sunday.
Naz Long added 16 for the Cyclones (3-0), who closed the game on a 23-10 run and held McGary to just one point in the second half.
"Melvin, I can't say enough about him. I told him in my office (Saturday), 'If you do get the green light, I'm going to gradually ease you back into this thing — and I think I took him out for two minutes in the second half. Pretty big-time performance from Mel," Hoiberg said.
McGary, a preseason first-team All-American who missed two games with a lower back injury, finished with nine points, six rebounds and four steals in 22 minutes.
"It was good to be back. Trying to find the right chemistry on the court. Typical first game, trying to find the right group of guys, try to feel it out and have a good feel on the floor," McGary said.
Nik Stauskas led Michigan (2-1) with 20 points and Derrick Walton Jr. had 13. Glenn Robinson III was held to 12 points on 4 of 14 shooting.
Michigan was just 8 of 29 from 3-point range and 4 of 9 on free throws.
"We did not execute the way we had to. They changed a little bit of pressure on their defense and blew up a couple of plays and we panicked a little bit. Out of that still...we had really good shots. They just didn't go down," Michigan coach John Beilein said.
Michigan kept threatening to pull away from the Cyclones in the second half — especially with Iowa State forward Georges Niang on the bench with four fouls.
Ejim kept the Wolverines from doing it.
Stauskas took a loose ball and flushed it home with an emphatic one-handed dunk, only to watch Ejim answer with a 3. Spike Albrecht then hit a layup, and Ejim responded with a jumper.
Iowa State's DeAndre Kane followed with a 3, and Long's 3 capped a 13-2 run that gave the Cyclones a 67-62 lead with 5:00 left.
