Hank O'Day
Henry Francis O'Day (July 8, 1862 – July 2, 1935) was an American right-handed pitcher, umpire and manager in Major League Baseball who worked as a National League (NL) umpire for 30 years between 1895 and 1927, and was the only person in major league history to appear as a player, manager and umpire. His 3,986 total games as an official ranked third in major league history when he retired, and his 2,710 games as a plate umpire still rank second in major league history to Bill Klem's total of 3,543. O'Day also umpired in 10 World Series – second only to Klem's total of 18 – including five of the first seven played. He is largely known for his controversial decision in a pivotal 1908 game, a ruling which still causes debate today.
