The Spartans seemed to rattle Robinson, intercepting a pass in the end zone on the opening drive of the game and picking off a third pass after he scored to pull Michigan within two TDs on the first play of the fourth quarter.
Robinson accounted for nearly 2,000 yards of total offense in his first five games, with only one interception, but wilted in his first true test against a good defense.
He was 17 of 29 for 215 yards and accounted for two touchdowns, but ran for a season-low 86 yards _ with a long of 16 _ on 21 carries.
Cousins threw for 284 yards.
Baker ran for 147 yards and Bell had 78 yards rushing.
Michigan State earned its most-lopsided victory in the series since beating the Wolverines 34-0 in 1967.

COLUMBUS, Ohio (AP) _ Terrelle Pryor is healthy, all right.
A week after leaving a win at Illinois with a strained muscle in his left thigh, he threw for a career-best 334 yards and three touchdowns to lead Ohio State.
The junior’s big day gave coach Jim Tressel his 100th victory on the Buckeyes sideline.
Pryor’s health had been a major topic of discussion around the Buckeye state all week, particularly since only minimal updates came out of practice from Ohio State’s coaches.
Pryor hit on scoring passes covering 22 yards to Dane Sanzenbacher, 60 yards to Brandon Saine and 17 yards to DeVier Posey as the Buckeyes (6-0, 2-0 Big Ten) rolled to their 12th consecutive win _ and 16th in a row over the Hoosiers (3-2, 0-2).
Indiana came in averaging 40 points and almost 350 passing yards a game, but quarterback Ben Chappell was harassed all day, completing 16 of 26 for 106 yards with two interceptions.
