ANN ARBOR, Mich. -- Michigan State guard Bryn Forbes hasn't played many games at the Crisler Center, but the Lansing, Mich., native made sure his last one would be a memorable one.
Forbes scored 29 points -- 23 coming in the first half -- to lead No. 10 Michigan State to an 89-73 blowout victory over Michigan on Saturday.
Forbes finished shooting 8-for-10 from 3-point range, going 7-for-9 in the first half. Senior guard Denzel Valentine flirted with a triple-double, scoring 21 points while grabbing nine rebounds and handing out eight assists.
Senior center Matt Costello chipped with 14 points and eight rebounds for the Spartans (20-4, 7-4 Big Ten), who have now won four straight after suffering through a three-game skid early in conference play.
Michigan (17-7, 7-4) struggled shooting the ball throughout the game, making just 8 of 28 from 3-point range.
Junior guard Zak Irvin scored 19 to lead the Wolverines while sophomore guard Aubrey Dawkins scored 14 and sophomore guard Derrick Walton Jr. added 11 points.
Michigan has lost two straight at home after getting hammered by Indiana on Tuesday.
Michigan State could hardly miss in the first half, opening an 18-point lead midway through the half. Forbes was the catalyst, hitting seven of his nine 3-point attempts in the opening 20 minutes, scoring 23 points to give the Spartans a 44-28 lead at halftime.
The Spartans got things rolling early as they hit their first five shots from long range while Michigan made just one of its first nine. The Wolverines were 4-for-16 from 3-point range in the opening half while Michigan State made 10 of 14.
Valentine had 12 points for Michigan State on 5-for-7 shooting, but he turned the ball over a couple of times.
Walton scored all 11 of his points in the first half, hitting a pair of 3-ponters in the final minute to keep the Wolverines in the game.
Michigan State poured it on in the second half, never allowing the Wolverines to gain any momentum, pushing the lead to 30 points before emptying the bench.
