CHICAGO (AP) -- Denzel Valentine joined some pretty elite company in Michigan State basketball history.
The senior guard had 29 points, 12 rebounds and 12 assists -- the 13th triple-double in Spartans' history -- and No. 13 Michigan State rallied for a 79-73 victory over No. 4 Kansas at the Champions Classic on Tuesday night.

Valentine flirted with a triple-double -- 13 points, eight rebounds and nine assists -- in the season opener against Florida Atlantic. He got it against a power program in Kansas and the points and assists were career-highs.
"I didn't know when it was going to come and I didn't think it was going to come on this stage, this early, but credit to my teammates," Valentine said. "They played a hell of a game. It wasn't pretty, but it got the job done."
Eight of Michigan State's triple-doubles were by Magic Johnson. Draymond Green had three and Charlie Bell one. Add Valentine to the list.
"There's a million things that he's not good enough at, but winning is something he is good enough at, work ethic is something he's good enough at and basketball IQ is something he's good enough at," Michigan State coach Tom Izzo said.
Kansas (1-1) had a 13-point lead twice in the first half, the last time at 28-15 with 6:16 to go. Michigan State (2-0) was within 41-35 at halftime but the Jayhawks again opened the lead to double figures at 61-50 with 9:42 to go on a long layup by Frank Mason III.
Valentine then scored seven points in a 12-1 run to tie the game at 62 with 6:08 to play.
There were six lead changes the rest of the way and it was Valentine who put the Spartans ahead for good at 72-71 on a drive with 1:29 left. He had 21 of his 29 points in the second half.
Valentine's understudy in the comeback was freshman guard Matt McQuaid, who scored six of his nine points on two 3s in the final 3:54 and then he came up with a huge blocked shot of Mason in the final minute.
"Matt McQuaid -- how about him -- big-time 3s," Valentine said. "He's somebody that impressed me this whole summer and this whole offseason and these first two games. He shows toughness, he always makes the right play. Who would come in as a freshman like that and knock (down) two big, gigantic 3 like that in Chicago, in the United Center on an NBA floor? I wouldn't have done it my freshman year. I'm glad he did it."
Perry Ellis led the Jayhawks with 21 points, Mason added 14 and Wayne Selden Jr. had 12.
"They made some big shots," Kansas coach Bill Self said. "They made some timely 3s, and we just didn't finish down the stretch I thought like we did the majority of the first 30 minutes of the game and Valentine just took over. He was great tonight."
"I've always thought he was a good player, but tonight I think he proved to everybody he's an exceptional player," Self added. "He totally controlled the game when they were coming back."
