Something finally slowed Auburn's momentum this season: archrival Alabama.

The Tigers tumbled down the rankings Monday morning, just hours after being swept by the Tide at Plainsman Park. It was the first time this season that Butch Thompson's club was on the wrong side of a series sweep, and it proved costly for Auburn.

The Tigers were ranked as high as fourth by Baseball America last week but slid all the way to 13th after losing three games in two days to Alabama, including a doubleheader loss Saturday and then a marathon, 15-inning affair late Sunday. It was the biggest drop of any team in the top 25 as Auburn went from atop the SEC standings to the middle of the pack in the conference in a span of 48 hours after Alabama more than doubled its SEC win total this weekend.

Despite the fall, Auburn (32-17) is still the fourth highest-ranked SEC in the Baseball America rankings. Mississippi State and Florida -- both teams that Auburn won its series against earlier this season -- are sixth and seventh, respectively, while Kentucky checked in at No. 9.

In the D1Baseball.com poll, Auburn also slid nine spots. The Tigers checked in at No. 14 after being ranked fifth last week. Auburn is behind four SEC teams in that poll. Florida is fifth, Mississippi State is seventh, Kentucky is ninth and LSU is 11th.
