LSU (12-6, 2-2 SEC) emerged with a victory over Auburn (11-7, 1-3 SEC) for the 10th time in the last 16 series meetings dating back to the 2004-05 campaign.
LSU scored nine of the 11 points during the extra period. On the defensive end, LSU pressured Auburn to misfire on six of its seven shots and commit a quartet of turnovers.
Coming off the bench for the first time in his LSU career, Anthony Hickey tallied a team-best 18 points on 6-of-12 from the floor, two shy of his career-high. He equaled a career-best with seven rebounds and dished out six assists.
Justin Hamilton connected for 13 points to notch double figures for the fifth straight outing to go along with a team-high eight rebounds, while Storm Warren tacked on 10 points and seven rebounds.
Ralston Turner added 11 points aided by a trio of three-pointers, his first double digit scoring outing since LSU's 67-59 victory over then-No. 10 Marquette back on December 19.
LSU nailed 44.1 percent of its shots from the floor compared to a 34.9 ratio for Auburn. Frankie Sullivan garnered a team-high 19 points, but the Auburn guard was shut out over the final 20:39 of the contest. He missed his final six attempts due in large part to Andre Stringer's suffocating defense.
Auburn built an eight-point advantage, 46-38 at the 11:32 mark of the second half. The Tigers ran off 22 of the 26 points ignited by a trio of Sullivan three-pointers during an 8:29 stretch. From that point forward, LSU forced Auburn into a 5-for-24 shooting clip.
LSU reeled off the next 10 points to regain the momentum. Malcolm White sparked the spurt with a turn-around jumper. Turner canned a three-ball coupled with Hickey and Warren lay-ups as LSU regained a 48-46 lead with 7:27 left.
The contest stayed within one possession for the remainder of regulation. Auburn forced the extra period as Varez Ward knocked down a triple from the top of the key with 0.2 seconds on the clock. It was Auburn's third shot attempt in a frantic final 10 seconds of regulation.
Hamilton opened the overtime scoring with a mid-range jumper to vault LSU back ahead 58-56. Three possessions later, Hickey found Stringer open in transition. He made his only shot of the game, a three-pointer from the right baseline, to extend LSU's to 61-56 with 1:24 remaining in the OT session. A Hamilton lay-up from Hickey, and two Hickey free throws put the finishing touches on the 65-58 win.
In the contest's opening minutes, LSU raced out to a 10-2 edge as the Tigers banged home three of their first five shots highlighted by two Turner three-pointers. LSU stretched it out to a 13-point spread, 28-15, after a Warren dunk.
Auburn trimmed its deficit down to 34-27 over the final five minutes of the stanza, and Sullivan heaved in a desperation shot from just inside halfcourt as the first half clock expired.
LSU returns to the road Saturday to square off with No. 14 Florida. Tip-off is slated for 5 p.m. CT, and the game will be televised by Fox Sports Network along with ESPN3.com
