They didn't score another basket until 13 seconds remaining in the half.
It took time for Purdue to capitalize on Minnesota's field-goal drought.
The Boilermakers didn't take the lead until JaJuan Johnson's jumper with about 3:30 left in the half. But then they added a three-pointer by Ryne Smith, E'Twaun Moore's free throw and five points by Chris Kramer in the final minutes to take a 35-28 lead into the break.
Kramer made a three-pointer at the buzzer.
Moore has eight points, and Kramer, Robbie Hummel and Johnson have seven points apiece. Hummel also has seven rebounds.
Purdue already has seven turnovers in the half -- that's as many as it had in each of the last two games.
- Minnesota has opted to trap sparingly. The Gophers have shown full-court pressure on the inbound but then dropped four of their players back into the half court. They did force a turnover by Moore when they used a trap in the backcourt, and Kramer was forced to call a timeout when he was trapped in the backcourt.
