NASHVILLE, Tenn. (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.

But the Commodores pulled within 70-66 on a layup by Riley LaChance with 34.7 seconds left, and they forced Washington into a turnover. LaChance was fouled on a 3-point attempt, then the senior missed all three free throws despite being an 88.9 percent shooter at the line.
Kentucky never led by more than nine. The Commodores fought back and took their first lead since the opening minutes at 56-55 on a layup by Peyton Willis with 7:58 left. Joe Toye's three-point play with 5:01 to go tied it for the third time at 59.
Vanderbilt, which thrives off shooting the 3, hit 6 of 25 against Kentucky. They were only 1 of 11 in the first half, staying close by hitting nearly every free throw (12 of 13) until going cold late in the half. Kentucky led 36-27 thanks to a 9-2 spurt where Vanderbilt hit only one field goal after an alley-oop dunk by Lee with 6:11 left.
Kentucky: 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.
Vanderbilt: 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.
