ANN ARBOR, Mich. (AP) -- Bryn Forbes scored 23 of his 29 points in the first half, part of an early barrage of 3-pointers by No. 10 Michigan State in an 89-73 rout of rival Michigan on Saturday.
Forbes made seven of the Spartans' 10 3-pointers in the half, and Michigan State finished 14 of 22 from beyond the arc. Long known for their rebounding and physicality, the Spartans (20-4, 7-4 Big Ten) have now made 47 3-pointers in their last three games. They beat Northwestern and Rutgers by a combined 65 points and the game against Michigan (17-7, 7-4) wasn't too competitive, either.
The Wolverines were without Caris LeVert, who missed a 10th straight game with a lower left leg injury. Zak Irvin led Michigan with 19 points.
Denzel Valentine had 21 points, nine rebounds and eight assists for Michigan State.
Forbes made his first five shots, all from 3-point range, as the Spartans raced out to a 32-15 lead. Michigan had problems at both ends, shooting only 8 of 28 from 3-point range for the game as Michigan State shut down guard Duncan Robinson.
Forbes added two more 3s in the final 45 seconds of the first half, and Michigan State took a 44-28 lead into the locker room.
Michigan is now 1-6 against Top 25 teams, and the losses have generally been decisive. The Wolverines allowed the final 25 points of the first half in a home loss to No. 22 Indiana on Tuesday.
The Spartans and Wolverines traded baskets for a little while in the second half. Michigan State eventually went on an eight-point run capped by Matt Costello's dunk that made it 69-42.
The Spartans have won four in a row over Michigan after losing six of the previous eight. The teams are only scheduled to play each other once this season.
