Nashville, TN (SportsNetwork.com) - K.T. Harrell led the charge as Auburn came alive late for an improbable 73-70 overtime victory over LSU in Friday's SEC Tournament quarterfinal game.

Harrell finished with 29 points and hit a 3 late in regulation to send the game into overtime.

Malcolm Canada finished with 14 points and two blocks, while Antoine Mason and Jordon Granger scored nine and eight points, respectively, for the 13th-seeded Tigers (15-19), who will face undefeated Kentucky in Saturday's semifinal game.

Granger was ejected during the second half after striking LSU forward Mickey Jordan's head.

Keith Hornsby led fourth-seeded LSU (22-10) with 24 points, while Jarell Martin totaled 18 points and 16 rebounds in defeat.

Harrell was fouled by Tim Quarterman twice with under two minutes to play. He hit the initial two free throws and made three more on the next possession to get Auburn within 62-61.

LSU got the ball back with 28 seconds left after Canada sent Josh Gray's shot attempt out of bounds with an authoritative block, but turned the ball over after the shot clock expired.

Martin blocked just enough of Canada's shot and Jalyn Patterson pulled down the rebound. Patterson was fouled on the play and nailed both free throws for a 64-61 edge with eight seconds to play.

Harrell rolled off a screen following the inbounds pass and knocked down a trey to tie the game with two seconds to play, sending the game into overtime.

Auburn took its first lead of the game on a pair of Harrell free throws 1:15 into the extra session. Harrell knocked down two more fouls shots and Antoine Mason's layup made it 70-64 with 2:36 to go.

Patterson fouled Mason's dunk with a trey and Gray got LSU within 72-70 on a layup with 40 seconds left. K.C. Ross-Miller supplied a free throw for Auburn, Hornsby missed twice from long range and Harrell stole the ball to seal the win.

LSU led 28-24 at halftime and was powered by Hornsby's 17 points on 6-of-9 shooting.
