The 1931 Athletics still hold the franchise record for most wins in a season (107-45). With the legendary Connie Mack running the dugout, and stars Al Simmons, Mickey Cochrane and Jimmie Foxx in full force, the A’s batted .287 as a team during a regular season in which they posted winning streaks of 13 and 17 games. However, when it came to concluding this historic season with a World Series triumph, the A’s fell short. They hit just .220 and clubbed only three homers while losing in seven games to St. Louis.
