NASHVILLE — (AP) Kevin Knox scored five straight points to put No. 21 Kentucky ahead to stay in a 74-67 victory Saturday, the Wildcats' second straight.
With the score tied at 59, Knox hit a jumper with 3:48 left and hit the free throw that put Kentucky ahead for good. He added a layup on the next possession for the Wildcats (14-3, 4-1 Southeastern Conference). Wenyon Gabriel added a tip-in, and Hamadou Diallo knocked down a 3-pointer for a 10-2 run clinching the victory.
Shai Gilgeous-Alexander led Kentucky with 22 points. Knox finished with 17 and Diallo and P.J. Washington each had 10.
Jeff Roberson led Vanderbilt (6-11, 1-4) with 20 points, and Saben Lee added 12.
Vanderbilt played most of the second half without senior guard Matthew Fisher-Davis because of an injured right shoulder.
With Quade Green out, Gilgeous-Alexander is showing why coach John Calipari had such a hard decision about who to start at point guard. He played 39 minutes along with Diallo.
The Commodores have lost seven games this season by single digits, and three of their four SEC losses all have been by single digits. ... Needing some size in the paint against Kentucky, coach Bryce Drew used 6-foot-10, 234-pound freshman Ejike Obinna for the first time in conference play. He played only 3 minutes, all in the first half, and got one rebound and one point.
