Tyler Kolek converted a steal into a go-ahead layup with 18 seconds left and Marquette forced 26 turnovers for a 67-66 comeback victory over No. 10 Illinois on Monday night.

Marquette (3-0) came back from a 12-point deficit in the second half to give new coach Shaka Smart his first signature win, despite going 3 of 9 from the foul line down the stretch.

Illinois (2-1) was clinging to a 66-65 lead when Kolek stole the ball from Trent Frazier at midcourt, maintained his balance and made a layup despite getting fouled. Kolek missed the ensuing free throw, but Kur Kuath stole the ball from Illinois guard Andre Curbelo with three seconds left to thwart the Illini.

Darryl Morsell scored 21 points, Justin Lewis had 17 and Kolek added 12 points.

For the Illini, Frazier had 23 points, including 6 of 10 3-pointers, while Coleman Hawkins scored 13 points and Jacob Grandison 10.

Illinois was playing without Associated Press preseason All-America center Kofi Cockburn, who was completing a three-game suspension.
