This day in Los Angeles Dodgers history saw Sandy Koufax break the National League record for strikeouts in a season on Sept. 27, 1961. The left-hander surpassed Christy Mathewson, who held the previous mark with 267 during the 1903 campaign. Koufax struck out seven batters over eight innings pitched in a 2-1 loss to the Philadelphia Phillies. It was the Hall of Famer's final start of the 1961 season, finishing with a then-record 269 strikeouts.
Robinson's iconic jersey number is also retired throughout Major League Baseball, and April 15 is designated as Jackie Robinson Day, celebrated by all players in his honor.
