With the Yelich news I think it's just Perkins + Black on the position side. Haase safe as well.
Only other realistic option is Hicklen, who is having a wretched August and would have to return to form at a minimum to enter the mix.
Also don't see anything flashy on the pitching side, with Megill, Milner, and Parades all on the IL and Hall in AAA. Between options, IL stints, and a DFA somewhere they'll probably bounce through all of them at some point in September. That's a decent boost and doesn't really warrant debuting Yoho or Misiorowski. Also doubt they would work to find a spot to try starting Patrick or Henderson over Ross/Wilson/Hall if another starter is needed. If we get locked into a seed, they'll probably just call Rodriguez up to eat some meaningless innings.
