AUBURN HILLS, Mich. — Glenn Robinson III scored 21 points and Mitch McGary added 13 points and nine rebounds, helping fourth-seeded Michigan overcome a rough night for star Trey Burke.
Burke made only two field goals and left the game briefly in the second half after a hard fall under the basket. The star point guard came back after that, but he finished with only six points.
Michigan (27-7) advanced anyway behind Robinson, McGary and Tim Hardaway Jr., who scored 21 points.
South Dakota State (25-10), the 13th seed, trailed by only four at halftime but couldn't keep up. High-scoring guard Nate Wolters was held to only 10 points.
Burke was held in single digits for the first time all season.
Michigan plays the winner of VCU against Akron on Saturday.

Troy Daniels had 23 points, Juvonte Reddic scored 21 and VCU routed Akron 88-42 on Thursday night in the most lopsided victory by a fifth-seeded team over a No. 12 in NCAA tournament history.
The previous mark was set by Wyoming in a 35-point win over Howard in 1981 and matched by Tennessee against Long Beach State in 2007, according to STATS.
The Rams (27-8) will play fourth-seeded Michigan on Saturday for a spot in the round of 16.
Akron (26-7) was seriously short-handed, and it showed.
