Purdue secured a notable win late Friday night against a gritty Illinois team to stretch its winning streak to 7 games.

The No. 1-ranked Boilermakers knocked off the No. 9 Illini 83-78 in the first top-10 matchup at Mackey Arena since Jan. 1, 2010.

Trey Kaufman-Renn scored a season-high 23 points, and big man Zach Edey had 10 points and 15 rebounds, as he became the second Purdue player with 1,000 career boards. Only Joe Barry Carroll has more than Edey’s 1,006.

After the game, Matt Painter spoke about Kaufman-Renn’s contributions.

“I just thought Trey was active,” Painter said. “The way he played tonight is the way he played the whole summer. That’s how he kinda got himself in this position. You don’t see it as much because he doesn’t play heavy minutes all the time, even though he starts. And then, when Braden’s (Smith) got it it rolling, or Zach’s got it rolling, sometimes you don’t get the ball as much. But I thought he was fabulous tonight. You want to grab an individual, he’s probably the difference for us.”

Kaufman-Renn helps Purdue with matchups against bigger lineups, Painter said. Kaufman-Renn also chipped in 4 rebounds, 2 assists and only one turnover.

“His ability to be around the rim,” Painter said. “Zach gets so much attention, a lot of times, the way the game is played now, you stay spaced and you let Zach just kind of maneuver down there and when we play different lineups, like with Mason in the game, we do that. But when him and Caleb are in the game at the 4, we’ve really tried to get them around the rim more and just try to hold the second-biggest guy on the court accountable.”
