NASHVILLE — On a night when the shots weren't falling for No. 2 Kentucky, John Wall still managed to deliver another tight win.
The Wildcats shot a season-worst 35.8 percent, but two free throws and a clutch block by Wall in the final 20 seconds gave them a 58-56 win over No. 17 Vanderbilt on Saturday night.
"He just fought his way," Kentucky coach John Calipari said of Wall, who shot 3-of-11 and finished with 13 points. "That will to win, refuse to lose. You just do what you got to do."
Kentucky (26-1, 11-1), which beat Vanderbilt 85-72 on Jan. 30, took a two-game lead over the Commodores in the SEC East and dealt them their first home loss since Jan. 25, 2009.
Wall's free throws with 20 seconds left gave the Wildcats a 57-53 lead, but John Jenkins hit a 3-pointer to pull Vanderbilt (20-6, 9-3) within a point.
Kentucky's Eric Bledsoe missed two free throws, but Wall bailed him out by blocking another 3-point attempt by Jenkins and grabbing the ball.
"That shot was going in," Jenkins said. "He bit, but I went up too fast. He made a good play."
Wall hit a free throw. A.J. Ogilvy caught Darshawn McClellan's long inbounds pass, but his runner in the lane bounced off the rim at the buzzer.
