Sox used Sale with a 4-1 lead in a clinching game on a Tuesday where he wouldn't have to pitch until Saturday. And if Sox needed to use him game 5 of ALDS, he'd have a full day rest between relief inning and start. Starters typically have a day of rest before their starts after their last bullpen session. Yes, postseason is for breaking rules (and we also used Kelly and Eduardo Rodriguez).

That said, if we think Sale will start much better with an extra two days due to his stomach thing, we probably should use him game 6 (Saturday) and then try and do a collective bullpen game with no one really doing more than 2 or 3 innings (and if we have a close game / late lead, use Sale / Price / Eovaldi along with our normal BP).
