In the playoffs.....if there is a 3-game series where a 3rd deciding game is played.....it usually happens the very next day.....weather-permitting. The teams that advance have days rest until the next round of playoffs the following week. So the pitching rules are not critical....except within a 2 or 3-game series. This is where pitching depth comes into play and why some teams opt for a one-gamer if they choose a coin flip and win the flip.
