Tracy Abrams scored 12 points, leading Illinois to a 53-46 win over No. 18 Michigan State on Saturday.
The Fighting Illini (17-12, 6-10 Big Ten) have three straight victories for the first time since winning four in a row from Dec. 21 to Jan. 4. That successful stretch included a win over then-No. 23 Missouri.
The Spartans (22-7, 11-5) have dropped two straight and six of their last 10 games. They were full strength for the first time in nearly two months, but simply weren't good enough to beat a streaking team that seemed more inspired.
Branden Dawson returned from a broken hand and played for the first time since Jan. 21, when he helped Michigan State beat Indiana to improve to 18-1 overall and 7-0 in conference.
Michigan State's Gary Harris had 19 points.
