During his career, Davidson was behind the plate for Hank Aaron's 715th home run which broke Babe Ruth's career record and he called the game in which Carlton Fisk hit a game-winning home run in game 6 of the 1975 World Series.
[3] His nickname came from his being a fan of the character "Sach" played by Huntz Hall in the 1940s films featuring The Bowery Boys.
[citation needed] Promoted to the National League in 1969 after only three years umpiring minor league baseball, Davidson was an umpire for the pair of no-hitters thrown on consecutive days during the first month of play that season at Crosley Field.
[4][6] He recalled that the stadium, which had been packed at the start of the game, was half empty by the seventh inning after the record was broken and said he "respected Hank because of the way he played and conducted himself" and that "it couldn't have happened to a nicer guy".
Davidson was the one who called it a home run, saying he had a better view of the ball than the umpires at third base and in left field.
