BLOOMINGTON, Ind. -- Will Sheehey comes off the bench for Indiana, but coach Tom Crean has often said he considers him a starter.

He showed why on Saturday. The junior forward scored a career-high 22 points to help No. 1 Indiana defeat Purdue 83-55 on Saturday afternoon.

Sheehey, who averages 10 points per game, set a school record for field-goal percentage by making all nine of his shots.

"I felt good," Sheehey said. "My teammates found me. I got excited I got to play a little more. You see a couple shots go in the hoop, your confidence goes up."

The outburst didn't surprise Crean because Sheehey puts in the work.

"He played outstanding," Crean said. "He's got the edge and all that, but he epitomizes a student of the game. He could run our walkthroughs. That's how locked in he is."

Cody Zeller had 19 points and nine rebounds, Christian Watford scored 14 points and Jordan Hulls added 11 for the Hoosiers (23-3, 11-2 Big Ten), who won their third in a row. Indiana shot 56 percent from the field overall and 62 percent in the second half.

Indiana's Victor Oladipo sprained his left ankle late in the first half and did not play in the second half. He is Indiana's No. 2 scorer and the team's top perimeter defender. Crean said he's not sure if Oladipo will be ready for Tuesday's showdown at Michigan State.

"I would go from precautionary to day-to-day," Crean said. "It's wait-and-see. He wanted to go back in, but we just weren't going to do that. None of us felt medically it was the best thing to do. I think he's going to be OK. It's wishful thinking to think he's going to play. We'll see how the next 36 hours play out."

Terone Johnson and Anthony Johnson each scored 11 points for Purdue (12-14, 5-8), which has lost three straight and five of six.
