WEST LAFAYETTE, Ind. -- When Purdue squandered a 17-point halftime lead Saturday and lost a home game to Iowa, Boilermakers senior guard Rapheal Davis took a long look into the mirror and didn't like what he saw.

"I let my teammates down against Iowa, but you have to keep working and get your head back into it," said the 20th-ranked Boilermakers' unquestioned leader after he bounced back with 16 points, five rebounds and six assists Thursday night in Purdue's 87-70 victory against Michigan in Mackey Arena.

Center A.J. Hammons added 17 points, five rebounds, three assists and four blocks against Michigan (12-4, 2-1 Big Ten), which had won six in a row but played without Caris LeVert. The Wolverines' leading scorer (17.6 points per game) sat out with a lower leg injury.

"Ray Davis willed us to victory tonight," Purdue coach Matt Painter said. "He was at the top of our plus-minus chart tonight. He is so accountable, that old soul that leads a program. I also really liked the way our point guards played tonight."

The Boilermakers used a 7-0 run that included a 3-pointer from guard Dakota Mathias, a dunk from Hammons and two free throws from point guard Johnny Hill to take a commanding 73-60 lead with 4:11 remaining.

Hammons made a 3-pointer and Hill added a layup for a 78-60 advantage with 2:32 to play, capping what became a 12-0 run after Michigan had pulled within 66-60.

Forward Vince Edwards scored 11 for Purdue (14-2, 2-1), and Hill added 10.

"Tonight, we were able to get stops when we needed them," said Davis, who was 6-for-6 from the free-throw line on a night when the Boilermakers were 18-for-21 (85.7 percent). "We limited them to 37.7 percent shooting."

Guard Muhammad-Ali Abdur-Rahkman scored 25 points, and guard Derrick Walton Jr. added 12 for the Wolverines, who were outscored 52-42 in a fast-paced second half during which Hammons had 11 of his 17.

"Purdue has a really good team, and their defense is terrific," Michigan coach John Beilein said. "We made it tough for them to score in the first half, but we were just not as good in the second half. You also have to know that Hammons is a game-changer. It is tough to score against them."

Purdue got a layup from forward Caleb Swanigan and two free throws from Davis to take a 45-35 lead with 16:15 remaining. Michigan closed within 50-45 on Abdur-Rahkman's layup with 12:48 to go, but Purdue center Isaac Haas scored on a dunk for a 52-45 Boilermakers advantage at the 12:06 mark.

Michigan closed to within 58-52, but a Davis 3-pointer at the 8:26 mark extended the Purdue lead to 61-52.

"This is such a tough environment, and they are a great defensive team," said Abdur-Rahkman, who made 10 of 16 field-goal attempts. "I usually am left open, so it is up to me to make shots."

His teammates were a collective 13-for-45 (28.9 percent).

Meanwhile, Purdue shot 76.2 percent in the second half (16-for-21) to finish at 55.6 percent (30-for-54).

Hill, whose mother traveled from Texas to see her son play, scored all 10 of his points during the final 20 minutes, playing what probably was his best game at the point.

"I feel like I hadn't been having the best games I could, but it's huge that I have the trust of my teammates," Hill said. "I definitely am a momma's boy, and I wanted to show her what it's like to see Mackey Arena really get rocking when we play well, which we did tonight."

A 3-pointer from point guard P.J. Thompson capped a 12-0 Purdue run and gave the Boilermakers a 31-23 lead with 1:52 remaining in the first 20 minutes.

Michigan got a 3-pointer from guard D.J. Wilson to pull within 31-26, but Purdue got a layup from Thompson and two free throws from Davis for a 35-26 advantage before Wolverines swingman Duncan Robinson made two free throws to close the first-half scoring.
