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. Philadelphia's pitching ace Lefty Grove, and George Earnshaw, the No. 2 man in 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. The Cardinals led the National League in runs scored and averaged six runs per game in the regular season, but could manage only two runs per game in this World Series. This was the Athletics' fifth World Series championship win (following , , and ), and their last in Philadelphia before moving to Kansas City in 1955 and then Oakland in 1968—where they have since won four more World Series titles (, , , and ). Their win this year tied them with the Boston Red Sox for most World Series wins as of that point (five) until , when the New York Yankees surged ahead of both in World Series wins and have gone on to amass 27 World Series championships as of 2020. The city of Philadelphia would have to wait 50 years until its next World Series championship, when the Phillies defeated the Kansas City Royals and thus became the last of the "Original Sixteen" MLB franchises to accomplish the feat. This World Series also marks the beginning of the Cardinals run of dominance in the National League in the early 1930s. They would win the pennant three times between 1930 and 1934 and the World Series in 1931 and '34. This would also be the final World Series where both teams uniforms did not have numbers. Summary Matchups Game 1 The A's managed only five hits off of Grimes in Game 1, but all were for extra bases and each produced a run in five different innings.
