Robinson scored 17 points in a reserve role, working both inside and outside. Ian Young came off the bench to spark the Tigers with 21 points, including 18 in the second half. Starter Marco Killingsworth did his damage inside and outside, too, on the way to scoring 20 points as he made 9-14 field goals as Auburn hit 56.6 percent of its shots.
Brandon Robinson was back in the groove.
LSU, ranked 24th nationally, came into the game a heavy favorite while riding a five-game winning streak. The 24th-ranked home team took its last lead at the 11:10 mark on a basket by Jaime Lloreda. Auburn then scorched the Bayou Bengals with a 21-0 run to take a 67-49 lead with 4:30 to play.
The 80 points Auburn scored was the most allowed by LSU this season. That didn't please Bayou Bengals head coach John Brad who said Auburn didn't allow his team to do the normal things it has done to win games. "We were leading the league in field goal percentage defense," Brady said. "We are second in the league in points allowed, just a tenth of a point behind South Carolina and we are right there in rebounding and we don't do either one.
"We can't stop them," Brady lamented. "They go around us. They shoot over us. They score around the goal. We had no answer for anything they did. We couldn't stop them. Sixty-eight points. If you told me that before the game, I would have said we are probably going to win because most people are scoring about 60 against us in the league and we give up 80 at home."
Auburn sent LSU's largest home crowd of the season, 11,024, heading home early. AU built the margin to 70-49 before LSU made a run to cut the gap to 72-60, but that was too little way too late as the visitors held on for a 12-point victory.
"We really took the fight to LSU," said Auburn coach Cliff Ellis, who saw his team out-rebound LSU 37-29. "It was a great effort. We controlled the game."
Ellis said the performance was as good as any his team has had this season. "I liked the way we played," he said. "I liked our energy."
Auburn signalled early that it was going to make this a fight by jumping out to a 7-2 lead and stretching the margin to 14-8. LSU caught Auburn at the 11:12 mark on three free throws by Tack Minor. Neither team could pull away the rest of the half that ended at 33-33.
LSU pulled ahead early in the second period and took a 43-37 lead on a three-pointer by Minor with 14:23 left to play. However, Auburn quickly rallied for a 46-45 lead on a basket by Robinson. After one more LSU basket, that set the stage for Auburn's 21-0 run.
Ian Young scored his Auburn high of 21 points.
LSU got 15 points from Minor, who hit 4-9 three pointers. LSU shot 38.5 percent on the night while Auburn hit 30-54 shots for 55.6 percent.
