Given how badly Camargo has hit from the left side, it's at least worth wondering whether Sandoval could be an option for the playoff roster. Really seems like a longshot but Panda has plenty of postseason experience, and he'd provide a LH platoon partner for Riley and LH DH option (which we don't have other than Schebler).
You'll be able to shrink the pen for the playoffs, so you can carry an extra bat or two. The only SP options will likely be Fried, Hamels, Anderson, and one of Folty or Wright - with one (or both) of the last two as pen options to replace Dayton and Webb. Would guess there's always the chance you leave whichever one isn't the 4th SP off the roster entirely (like Julio last season). If you're going to carry the guys that miss the most bats in round one, you're looking at...
Fried
Hamels
Anderson
Melancon
Smith
Martin
Minter
Greene
Matzek
O'Day
Jackson
Touki
Wright/Folty as your Game 4 SP and the other as your long man
That'd give you 4 multi-inning options if you count Matzek. If you did that you'd have room for the extra LH bat.
