D'Angelo Russell scored 22 points, including eight during a decisive 15-0 second-half run, in leading No. 20 Ohio State past Illinois 77-61 on Saturday in Columbus, Ohio.

The Buckeyes (12-3, 1-1 Big Ten) trailed by eight in the first half and by three in the early minutes of the second. But they turned the tide with an attacking, opportunistic man-to-man defense instead of the 2-3 zone they had played all season.

"They shot us out of it, to be honest with you," Ohio State coach Thad Matta said, referring in particular to Rayvonte Rice, who scored 20 points. "It's like we told our guys, it wasn't like they were shooting 21- footers. They were shooting from 24 feet and they were going in."

Sam Thompson and Marc Loving each had 13 points for the Buckeyes, who bounced back from a conference-opening 71-65 home loss to Iowa on Tuesday. They visit the Gophers on Tuesday.

The Illini (10-5, 0-2) didn't score in a stretch between Kendrick Nunn's three-pointer at the 16:33 mark until Nnanna Egwu's two foul shots with 11:06 remaining. Russell's three-pointer after a five-second call on an Illinois inbounds play made it 56-44. Illinois never threatened again.

"This one's pretty simple: 20 turnovers and we gave up 60 percent from the field," Illini coach John Groce said. "We weren't able to defend them from start to finish. The second half, not taking anything away from them because they played really well, but it was the worst basketball we've played all season."

Purdue 64, Michigan 51: The Boilermakers made an emphatic statement over the final 20 minutes, allowing just four baskets, 18 points and no offensive rebounds as they rallied from an eight-point halftime deficit to pull away from the defending Big Ten champs in West Lafayette, Ind.

Vince Edwards finished with 16 points and six rebounds for Purdue. A.J. Hammons had 15 points and 12 rebounds, falling just short of a season-high in points after the official scorers erased a basket that had been tipped in by Michigan's Aubrey Dawkins.

Purdue (10-5, 2-0) had let its past four opponents score 83.0 points and shoot 52.0 percent from the field. It looked like that trend might continue when Michigan (8-6, 1-1) went 6-for-11 on three-pointers to build a 33-25 halftime lead.

Caris LeVert, the Wolverines' top scorer, was held to six.

Rutgers 50, Penn State 46: The host Scarlet Knights (9-6, 1-1) got their first Big Ten victory, led by Kadeem Jack's 12 points and 11 rebounds. Big Ten scoring leader D.J. Newbill scored 14 points for the Nittany Lions (12-3, 0-2), nearly eight below his average.
