The last time Auburn baseball swept LSU, current head coach Butch Thompson was a senior at Amory High School and Frank Thomas was Auburn’s first basemen.

That 37-year drought ended Sunday afternoon, as Auburn took Game 3 from the visiting Tigers 3-2, completing the sweep and improving to 26-10 overall on the season.

This weekend was Auburn’s second consecutive series win, taking two out of three versus Alabama last weekend after getting swept by Georgia. Despite it being the program’s first sweep over LSU since 1988, it’s the third time in four seasons Auburn has won a series over the Bayou Bengals.

“Our guys came together and played every facet. Great baseball, sound baseball,” Thompson told reporters after Sunday’s game. “LSU was going to have to beat them, for the most part. And then our crowd, the largest series ever at home — it just all came together and synced up this weekend.”

The series against LSU coincided with Auburn’s annual A-Day weekend, which brought more fans than usual to Plainsman Park. Auburn set a program record for combined attendance across a single series, with 19,119 fans attending the series.

It now puts Auburn at 9-6 in Southeastern Conference play at the halfway point of the SEC schedule, a favorable spot before traveling to play three games against No. 2 Texas next weekend.

Auburn’s pitching stood out more than anything else across the weekend. The home Tigers gave up baserunners throughout the series, but constantly kept LSU’s deep lineup from capitalizing.

Keeping LSU’s lineup quiet for one game can feel like a tall task, but a whole series is an even steeper mountain to climb.

That’s why Griffin Graves’ strikeout against LSU’s Daniel Dickinson with the bases loaded and two outs in the fifth inning Sunday felt like a perfect summary of the weekend.

Thompson admitted that going into the game that he didn’t think three runs would be enough to win, but forcing LSU to strand the bases loaded in the fifth inning was a turning point.

“When Griffin got out of that, it started feeling possible,” Thompson said.

It was one of many occasions throughout the series in which LSU put runners on base, but Auburn kept it from capitalizing and breaking the game open.

LSU outhit Auburn 8-7 in Game 2, but Auburn still won 4-2. It was another case of LSU leaving runners on base and Auburn consistently winning the big moments.

Game 1 was also defined by pitching, albeit in a different way. It was Auburn ace Sam Dutton’s first game back against his former team, and he delivered six shutout innings to help Auburn win 8-4.

The pitching staff consistently delivered in all three games. What makes that notable is the lineup Auburn was up against. LSU entered the series second in the SEC in batting average and tied for sixth in the country in runs, but was unusually quiet against Auburn.

“They have had our backs a lot this year,” Auburn outfielder Ike Irish said of the pitching staff. “I think early in the season you saw them pitch at a high level and offensively we weren’t there yet. Middle of the season it kind of flip-flopped. I feel like this weekend we put it all together offensively, defensively and the pitching staff.”

The sweep puts Auburn safely in the top half of the SEC standings with a tough stretch to end the season ahead. Auburn’s next series is on the road against No. 2 Texas, and the Tigers still have road series left against No. 5 Tennessee and No. 6 Ole Miss.

There’s still a long way to go before the 2025 campaign shifts into the postseason, but Thompson is satisfied with his group’s progress at the midway point of conference play.

“The last two weekends at home, it’s been great. Going two weekends on the road back-to-back is not for the faint of heart,” Thompson said. “I think everybody got a sense and feel what this club’s all about. A little flash of what could be from this weekend.”
