Reserve guard J.P. Blevins scored nine points, all on three-pointers, sparking unranked Kentucky's comeback from a 15-point first-half deficit as the Wildcats upset No. 5 Michigan State, 60-58.
Averaging just 2.2 points per game, Blevins was a surprising hero for the host Wildcats (6-4), who looked unlikely to give the Spartans (8-3) much of a game when they fell behind, 26-11, with 6:12 left in the first half. In the second half, Blevins hit two treys, including the shot that gave the Wildcats the lead for good, 50-49, with 7:18 left.
The Spartans got within 60-58 and had the ball for a final shot, but Andre Hutson's baseline shot was blocked and Morris Peterson's rebound tip-in attempt was no good as time expired.
"I was impressed with our composure and poise to not panic," Kentucky coach Tubby Smith said. "We've grown up a lot over the last two weeks."
Jamaal Magloire led Kentucky with 18 points and 11 rebounds and Tayshaun Prince added 17. Peterson led the Spartans with 18 points. Jason Richardson had nine rebounds.
