The 1930 World Series featured the defending World Series champion (and 1930 American League (AL) champion) Philadelphia Athletics against the National League (NL) champion St. Louis Cardinals. The Athletics defeated the Cardinals in six games, 4–2. Philly's pitching ace Lefty Grove, and George Earnshaw, No. 2 man in Mr. Mack's rotation, won two games apiece. Earnshaw also pitched seven scoreless innings as Game 5 starter, but ended up with a no-decision as Grove relieved him in the eighth and took the win on Jimmie Foxx's two-run homer in the top of the ninth for the game's only scoring.
