EAST LANSING, Mich. — Draymond Green had 23 points and 12 rebounds and made some timely shots to help No. 11 Michigan State pull away from Penn State in a 77-57 win Wednesday night.

The Spartans (19-5, 8-3 Big Ten) pulled within a game of conference-leading and third-ranked Ohio State, setting up a big game Saturday on the road against the Buckeyes.

The last-place Nittany Lions (10-15, 2-10) have lost five straight and eight of nine.

Michigan State's Adreian Payne matched a career high with 12 points and freshman Branden Dawson also had 12, scoring in double figures for the fifth straight game.

Tim Frazier scored 19 on 6-of-18 shooting for the Nittany Lions.

Michigan State led by 21 early in the second half. Penn State posed a brief threat by pulling within five points midway through the second half, but Green made a layup on the next possession.
