The loss was the first home conference loss in John Calipari's tenure as Kentucky's coach. Kentucky had won 24 straight home SEC games before Saturday.
Texas A&M (12-3, 2-0) held an advantage as large as nine points early in the second half, but the Wildcats took a lead with a 12-2 run, a lead they stretched to four points.
With the game tied at 63 with 4:04 to play, Aggies guard Fabyon Harris hit a jumper to help send them on a string of 11 unanswered points to close out the game. Harris scored nine points in that stretch for the Aggies and finished with 14.
Turner, a 6-foot-5 senior whose previous career high was 26, had 25 points at halftime for the Aggies. He was 10 of 13 from the field in the first half, including a perfect 7 of 7 from inside the 3-point line. Turner was considerably cooler for most of the second half, but he came alive in the game's final 7 minutes.
He hit a pair of 3-pointers to stop Kentucky runs, the second of which closed a four-point Kentucky lead -- the Wildcats' largest lead of the game -- and ended the Wildcats' last run of the game.
Nerlens Noel finished with 15 points, 11 rebounds, seven blocks, six assists and four steals for the Wildcats. It's the third time this season Noel has had seven blocks in a game.
Archie Goodwin led the Wildcats with 17 points.
