COLUMBUS, Ohio -- Evan Turner hit two jumpers down the stretch and Jon Diebler added two clinching free throws to lead Ohio State past Northwestern 52-47 on Sunday.
Ohio State (20-9, 10-8), which nearly blew a 12-point second-half lead, will be the No. 5 seed and Northwestern No. 9 at the Big Ten tournament in Indianapolis.
The win kept coach Thad Matta's streak of 20-win seasons intact, making him 9-for-9 as a head coach.
Turner had 17 points, Diebler and William Buford 11 apiece and B.J. Mullens 10 for the Buckeyes, who had no seniors to honor at a final home game.
Craig Moore scored 18 points -- including a late four-point play -- for the Wildcats (17-12, 8-10). Kevin Coble added 13 and Michael Thompson 12.
