I was gonna mention to welch that the greatest managin' job in a WS 7th game was Danny Murtaugh in 1960. The genius of havin' Maz bat in the bottom of the 9th.
Maybe, but Bucky planned it out: rookie RH Curly Ogden started so John McGraw, thought to be a baseball genius, started his left-handed lineup. That included Bill Terry, future HoF. Ogden was a spot starter. He was supposed to pitch to the first batter, while lefty George Mogridge warmed up under the Griffith Stadium grandstands. Ogden struck out the first guy, so Harris let him pitch to another batter, then put in Mogridge. That's probably the shortest start in a WS game, unless a pitcher got hurt.
