INDIANAPOLIS (AP) -- Branden Dawson had 16 points and Gary Harris added 13 points to lead No. 22 Michigan State to a 67-51 victory over Northwestern in a Big Ten Tournament quarterfinal Friday night.
The third-seeded Spartans (24-7), who lost three of four games heading into the contest, will face No. 12 Wisconsin in one semifinal on Saturday.
Drew Crawford scored 21 points and Alex Olah finished with 10 for the 11th-seeded Wildcats (14-19), who lost to the Spartans in the league tournament for the fourth time.
Michigan State went on a 13-3 spurt in the first half and then extended the lead with a 9-3 run in the second half.
Denzel Valentine made a free throw, and Keith Appling, Adreian Payne and Dawson each scored. Harris made a reverse lay-up and hit a 3-pointer to put Michigan State ahead 57-33 with 9:23 remaining.
The Spartans started Payne, Dawson, Valentine, Harris and Appling for the third straight game. The five started the first two games of the Big Ten season, but because of either injuries or illness, the five didn't start together again until Michigan State's win over Iowa on March 6.
Spartans coach Tom Izzo had every player available for only the final three regular-season games.
In the first half, Tre Demps hit a jumper to make it 27-17 before the Spartans pulled away.
Harris made a pair of free throws and a lay-up to put the Spartans ahead 31-17 at the start of the 13-3 run.
Crawford hit a pair of free throws to make it 40-22 at halftime.
Harris blocked a shot by Crawford and Payne made a 3-pointer, and Appling scored to give the Spartans a 45-22 advantage to start the second half.
Then the Wildcats went on an 8-0 run.
Nikola Cerina scored and Crawford made a pair of free throws and two baskets to make it 45-30 with 14:55 remaining before the Spartans pulled away again.
