ANN ARBOR (AP) — Andre Curbelo scored 11 of his 17 points in the first half, and No. 4 Illinois dismantled No. 2 Michigan with a smothering defensive performance, routing the Wolverines 76-53 on Tuesday night.

Playing again without injured star Ayo Dosunmu, the Illini (19-6, 15-4) kept Michigan from clinching the Big Ten title and boosted their own chances at a No. 1 seed in the NCAA Tournament. Trent Frazier led Illinois with 22 points, and Kofi Cockburn added 12.

Eli Brooks scored 11 points and was the only player in double figures for Michigan. The Wolverines (18-2, 13-2) looked physically overwhelmed for much of the night, unable to create good shots against the Illinois defense and unable to keep the Illini off the boards. It was an eye-opening blowout — especially since Michigan has rolled to similar margins of victory against other good teams this season.

Both teams had a hard time scoring in the first half, but Curbelo’s ability to drive to the basket helped Illinois to a 33-22 lead at the break. Then the Illini kept pouring it on.

Illinois outscored Michigan 22-5 in second-chance points and held the Wolverines to 35% shooting from the field.

The Big Ten confirmed before the game that it will use winning percentage to determine the league champion. Michigan can still wrap that up with a win in either of its last two games — or if Illinois loses its last game this weekend.

BIG PICTURE

Michigan: It’s only one game, and the Wolverines had been remarkably consistent in their dominance of the Big Ten this season — but Michigan looked so lacking in energy and offensive poise Tuesday that it will be interesting to see the team’s response later this week.

POLL IMPLICATIONS

This is a tricky one to evaluate. Michigan may drop behind No. 3 Baylor. Illinois could certainly pass Michigan as well after this game, but the Illini still have four more losses than the Wolverines. Plus, both Michigan and Illinois have more tests to come before the next poll.

UP NEXT

Michigan: The Wolverines finish the regular season with a home-and-home series against rival Michigan State, starting Thursday night in Ann Arbor.

MICHIGAN STATE 64, INDIANA 58

EAST LANSING– Aaron Henry had 18 of his 22 points in the second half, leading Michigan State to a 64-58 win over Indiana on Tuesday night in a matchup of teams on the bubble to play in the NCAA Tournament.

The Spartans (14-10, 8-10 Big Ten) broke a ninth-place tie in the highly touted conference with the Hoosiers (12-13, 7-11) in a possibly pivotal game for their postseason hopes.

Michigan State’s Joshua Langford scored 13 points and Gabe Brown added 10 points for a team that has won four of its last five games.

Rob Phinisee scored 16 points and was Indiana’s only player in double figures.

Trayce Jackson-Davis was held to a season-low nine points and matched a career low by making only one shot on five attempts. The sophomore forward scored a career-high 34 points in the last game against Michigan State and averages nearly 20 points a game.

Indiana has lost four in a row and five of its last six games. The late-season slide has hurt the Hoosiers chances of going to the NCAA Tournament for the first time since 2016 when former coach Tom Crean helped them earn a bid for a fourth time in five seasons.

Michigan State greatly improved its chances of playing beyond the Big Ten Tournament by beating then-No. 5 Illinois and then-No. 4 Ohio State last week at home. Those desperately needed quality wins followed a victory against the Hoosiers on the road.

Henry matched a career high with 27 points in the previous meeting, leading Michigan State to a 78-71 comeback win at Indiana less than two weeks ago. That victory was a third Quadrant 1 win this season for a team hoping to close a shaky season strong enough to play in a 23rd straight NCAA Tournament.
