Pretty sure you need 4 starters in the playoffs. At least for a 7-game series, unless you're going to throw them on 3 days rest. You also need someone to provide length in the pen if the starters falter or Hyde has a quick hook. Here are my guesses in order of confidence
Starters: Burnes, Efflin, GRod (if healthy), Suarez
Long man: Kremer (though you could swap him with Suarez)
Bullpen: Dominguez, Cano, Coulombe (if healthy), Webb (if healthy), Perez, Kimbrel, Smith and one of Soto/Akin/Povich
I hate that GRod, Coulombe and Webb are question marks.
