Hopefully I'm not beating a dead horse, but if we're talking about the NLDS (and let's not get ahead of ourselves), there are only 3 starters. Given how emphatic Murph has been about Quintana having a role in this postseason, my guess is if he's feeling ok it'll be Quintana, with Patrick starting if he can't go. Depending on the score it could be a piggyback with the two of them (or Myers), otherwise with the off days we can easily throw the BP A team out there to lock it down.
Re status, latest I heard was Hall and Q are both throwing, so they would likely be physically able to pitch, it's just they may have had no real work before the playoffs.
