Firpo Marberry, American baseball player and umpire (born 1898)

Frederick "Firpo" Marberry was an American right-handed starting and relief pitcher in Major League Baseball from 1923 to 1936, most notably with the Washington Senators. The sport's first prominent reliever, he has been retroactively credited as having been the first pitcher to record 20 saves in a season, the first to make 50 relief appearances in a season or 300 in a career, and the only pitcher to lead the major leagues in saves six times. Since relief pitching was still seen as a lesser calling in a time when starters were only removed when clearly ineffective, Marberry also started 187 games in his career, posting a 94–52 record as a starter for a .644 winning percentage. He pitched in later years for the Detroit Tigers (1933–1935) and New York Giants (1936) before ending his career in Washington.
