Jon Teske scored all 17 of his points in the first half, and No. 2 Michigan is now off to its best start in program history after an 80-60 victory over Northwestern on Sunday night.
The Wolverines (17-0, 6-0 Big Ten) started 16-0 on two previous occasions, but this season's team surpassed that by routing Northwestern. Zavier Simpson scored a career-high 24 points for Michigan, and Teske matched his own career high in scoring.
The 7-foot-1 Teske made three 3-pointers, plus a couple more midrange shots. Simpson — who entered the game shooting 29 percent from 3-point range — connected five times from beyond the arc.
Northwestern (10-7, 1-5) was without leading scorer Vic Law, who was out with a lower-body injury. Dererk Pardon scored 20 points for Northwestern.
Michigan also started 16-0 in 1985-86 and 2012-13. The Wolverines have matched the longest winning streak in school history. They won 17 in a row in 1985 before losing in the NCAA Tournament.
Michigan and Virginia are the only unbeaten teams remaining in Division I.
No. 6 Michigan State 71, at Penn State 56: Nick Ward had 16 points and 11 rebounds to lead Michigan State past Penn State.
Matt McQuaid added 15 points and Cassius Winston chipped in 11 for the Spartans (15-2, 6-0 Big Ten), who have won 10 straight. They also beat the Nittany Lions (7-10, 0-6) for the 10th consecutive time.
