Ryne Smith scored 18 points Sunday to help No. 11 Purdue beat Iowa 75-52, the Boilermakers' 10th straight win.

Smith made a career-high six 3-pointers, surpassing his record of five set twice in the previous three games.

JaJuan Johnson had 16 points and four blocks and E'Twaun Moore and Kelsey Barlow each added 11 points for the Boilermakers (15-1, 4-0 Big Ten). Purdue shot 49 percent from the field and outrebounded the Hawkeyes 36-29. The Boilermakers won easily even though its top two players, Johnson and Moore, shot a combined 12 for 32 from the field.

The Boilermakers held Iowa to 37 percent shooting and forced the Hawkeyes into 16 turnovers.

Matt Gatens led Iowa with 13 points, but no one else reached double figures for the Hawkeyes (7-8, 0-3). Iowa gave No. 2 Ohio State a battle on Tuesday and led the Buckeyes at halftime before losing 73-68.

Smith only reached double figures once in non-conference play, but he has done so in all four Big Ten games. He is averaging 17 points and shooting 18 for 27 from 3-point range against league opponents.

Purdue is averaging 80 points in conference play and winning by an average of 18.5 points. The Boilermakers will face their biggest test yet when they play at Minnesota on Thursday.

Purdue opened the game against Iowa by taking an 11-0 lead. The Hawkeyes went scoreless for the first 5:22, missing three field goals and committing five turnovers.

Iowa made a run, but Lewis Jackson's long jumper and Smith's 3-pointer put the Boilermakers up 22-8.

Barlow scored eight straight points for the Boilermakers in a stretch that gave Purdue a 31-14 lead, and the Boilermakers led 34-20 at halftime.

Purdue pushed its lead to 50-29 after Barlow completed a three-point play with 14:16 remaining. A basket in close by Terone Johnson pushed the lead to 30 with 4:46 to go.
