WEST LAFAYETTE, Ind. (AP) -- Freshman Caleb Swanigan scored a career-high 27 points and sophomore P.J. Thompson also set a career best with 22, leading No. 15 Purdue to a 91-80 victory against Wisconsin on Sunday.

A.J. Hammons added 16 points and Vince Edwards had 11 for the Boilermakers (24-7, 12-6), who forced a four-way tie for third place in the Big Ten with Maryland, Iowa and Wisconsin.

Purdue earned the No. 4 seed in the Big Ten Tournament and will play in Friday's second semifinal against an opponent to be determined.

Nigel Hayes led Wisconsin (20-11, 12-6) with 30 points, including 18 in the second half. The Badgers earned the No. 6 seed in the conference tournament and will play Thursday in Indianapolis' Bankers Life Fieldhouse.

The Badgers, who had a four-game winning streak snapped, are the reigning Big Ten Tournament champs.

After Thompson made five first-half 3-pointers, the Badgers were forced to extend their defense and Swanigan, Purdue's power forward, had a 23-point second half. The Boilermakers will take a three-game winning streak into the Big Ten tourney.

The Boilermakers opened the second half with a three-point play from Swanigan and a steal and dunk from Edwards to seize a 50-39 lead with 18:12 remaining. Swanigan's layup pushed the advantage to 52-39 at the 17:09 mark.

Purdue shot 63 percent (17 of 27) during the first half and led 45-39 through 20 minutes, getting 15 from Thompson on 5 of 6 from 3-point range.

After Wisconsin, which shot 57.1 percent in the half (16 of 28) took a 29-21 lead, the Boilermakers finished the half outscoring the Badgers 24-10, including six 3-pointers. Purdue also outrebounded Wisconsin 13-7 during the first 20 minutes, when Hayes scores 12 for the Badgers.
