Jeroloman lined a one-out single off of LSU reliever Jordan Faircloth in the 10th to start the Auburn rally. Faircloth was lifted for left-hander Greg Smith, who struck out center fielder Clete Thomas.
Bell then drilled a Smith offering off of the right-center field wall, as Jeroloman's headfirst slide just beat the throw in from the outfield.
Faircloth (0-3) was charged with the loss, though he pitched a solid 3.2 innings, allowing one run on five hits with no walks and three strikeouts.
Auburn closer Steven Register (5-0) earned the win despite allowing a two-run homer in the ninth inning by LSU first baseman Clay Harris, a blast tied the game at 6-6. Register worked three innings, surrendering two runs on five hits with no walks and two strikeouts.
Auburn led 6-4 in the ninth when center fielder J.C. Holt led off the inning with a double against Register. Matt Liuzza struck out and Nick Stavinoha popped out to third, but Harris launched a two-run shot to right-center field, his third homer of the season and his second in two games.
LSU grabbed a 2-0 lead in the first inning against Auburn starter Mike Felix as Stavinoha provided and RBI double and Harris contributed a sacrifice fly.
LSU added a run in the third on Stavinoha's RBI single, but Auburn sent 10 men to the plate in the fourth inning, scoring four runs -- two earned -- on five hits with two LSU errors.
LSU narrowed the gap to 5-4 in the fifth on Harris' RBI single, but Auburn stretched the lead to 6-4 in the bottom of the frame on J.T. Williamson's run-scoring single.
Auburn, which finished the game with 17 hits, maintained the 6-4 lead until Harris' ninth-inning homer, setting the stage for Bell's heroics in the 10th.
