Reggie Hearn scored a career-high 26 points to lead Northwestern to a 75-60 victory over Purdue on Saturday.
Jared Swopshire and Dave Sobolewski each added 13 points for the Wildcats (13-10, 4-6 Big Ten), who snapped a four-game losing streak to the Boilermakers.
Purdue freshman center A.J. Hammons didn't start because he was late for the team bus from West Lafayette, Ind., according to a team spokesman. Hammons did lead the Boilermakers (11-11, 4-5) with 19 points and 13 rebounds.
Hammons had 30 points, his highest total of the season, in a loss to No. 3 Indiana on Wednesday.
Travis Carroll started in Hammons' place, and Hammons entered with 16:44 to play in the first half. The Boilermakers scored their first points with 15:59 left on a Hammons tip-in to cut the lead to 12-2.
The Wildcats shot 11 of 26 from 3-point range and 53 percent from the field.
