ANN ARBOR, Mich. – Trey Burke scored a season-high 29 points and freshman Glen Robinson III matched a career high with 21 to help No. 4 Michigan bounce back from an embarrassing loss with a 79-71 victory over Penn State on Sunday.

The Wolverines (22-4, 9-4 Big Ten) had dropped three of their previous four games, including a 23-point loss Tuesday night on the road against No. 8 Michigan State, and needed a half to shake off their slump.

Michigan appeared to still be struggling to get over its blowout against the rival Spartans when it trailed for much of the first half against a last-place team without a conference win.

The Nittany Lions (8-17, 0-13) led by as many as eight points in the first half. They went ahead 7-plus minutes into the game and had the lead until Burke made a game-tying, off-balance fadeaway with 55 seconds left in the first half.
