Are you going to guard me?

Adreian Payne said that with his body language a few times Thursday at Mackey Arena — catching the ball, looking around for a moment, all but shrugging before floating another perfect jump shot through the rim.

“After a minute it just seemed kind of awkward,” Payne said after Michigan State’s record-breaking, 94-79 rout of Purdue, “like they didn’t catch on to it.”

Payne’s three-pointer on the first possession helped MSU catch fire early, and Travis Trice’s late triple gave the No. 13 Spartans a single-game school record of 17 three-pointers in a bounce-back, feel-good victory to give MSU (22-5, 11-3 Big Ten) a half-game lead over Michigan in the Big Ten race.

And now it’s on to Ann Arbor.

“It’s gonna be a war,” said Payne, who missed MSU’s Jan. 25 home loss to Michigan with a foot sprain. “We know it’s a big game, and we know we’ve got to come out and just play. … I had to sit there and watch the team take (a loss) at home, and I just wish I could have been out there to help. But I’m very excited about this game.”

Most of Payne’s teammates had little to say about Sunday’s rematch in Ann Arbor — Keith Appling said MSU will start thinking today about “the team that we play Sunday” — but there was little chance they’d be dwelling on the rout of the Boilermakers (15-11, 5-8).

“I told them they can enjoy this win until they get to the airplane,” coach Tom Izzo said of his players. “It’s kind of a big game coming up.”

But Thursday’s was as well, especially in light of MSU’s stunning, 60-51 home loss Sunday to Nebraska. The Spartans were 5-for-24 from three-point range in that game.

They were 13-for-19 on threes with 49 points at halftime Thursday in a game that had plenty of offense and too little defense on both sides. The Spartans finished 17-for-32 from long range, beating the school record of 16 threes set in a 114-63 rout of U-M in the 1999-2000 national title season.

“I knew it was gonna be a good night from the jump,” said sophomore guard Gary Harris, who blasted out of his shooting slump with a game-high 25 points and 6-for-9 accuracy on threes, in the arena where his mother became a Purdue All-America.

Payne was 4-for-8 from long range and scored 23 points. Trice was 4-for-6, including the record breaker with 4:29 left, and had 14 points, and Denzel Valentine tied his career scoring high with 16 points.

MSU also got threes from Kenny Kaminski and Russell Byrd, and Appling played 25 minutes and had a game-high nine assists. The Spartans had 26 assists on their 30 baskets.
