Cody Zeller had 15 of his 19 points in the second half and fifth-ranked Indiana opened Big Ten play by holding off Iowa 69-65 on Monday night.
Victor Oladipo scored 14 points for the Hoosiers (13-1, 1-0 Big Ten), who snapped a four-game losing streak in Iowa City and have now won four straight since losing to Butler two weeks ago.
Oladipo beat the shot clock with a putback with 1:04 left to put the Hoosiers ahead 65-60. He also made two key free throws with 26 seconds to go to make it a two-possession game.
Aaron White had 15 points to lead Iowa (11-3, 0-1), which might have pulled off the upset had it shot better than 3 of 17 from 3-point range.
