In modern day baseball, teams generally have five starting pitchers, and they take it in turn to start a game every fifth day (hence the phrase rotation). Sometimes, if the schedule pans out, a team can get away with a four man rotation, and in the distant past some teams managed a three man rotation.
A big league pitcher will make about 4-7 mistakes a game (some get fouled off, others get hammered out of the park). A 'AAA' pitcher will make 7-11 mistakes a game, the margins are very slim; there are many 'AAAA' players who earn a good living playing baseball as they bounce up and down between MLB and the minors.
