This day in baseball: The Iron Horse’s final slam

On August 20, 1938, Lou Gehrig hit a grand slam in the first inning against Philadelphia’s Buck Ross.  It was the twenty-third, and final, grand slam of the Iron Horse’s career, which extended his career Major League record.  The Yankees went on to defeat the Athletics 11-3.  The record has since been broken by Alex Rodriguez, with 25 grand slams.
