Victor Oladipo’s go-ahead putback, dunk and free throws in the final minute lifted top-ranked Indiana to a 72-68 win over No. 4 Michigan State on Tuesday night at East Lansing, Mich.

Indiana (24-3, 12-2 Big Ten) broke a first-place tie in the conference and moved a step closer toward earning top seeding next month in the NCAA Tournament. The Hoosiers had lost 17 straight — since 1991 — on the road against the Spartans.
