There aren't really any battles.
Bench is Altherr, Williams, Knapp and Kingery. If they decide not to use five starters for a while, Walding or Cozens could still get a look, or Rodriguez could be added to the 40 (I'm assuming he will go to LV in any case).
There is not a rotation battle. I believe that was Anderson's last start.
With Hunter out Arano, Rios, Ramos or Pazos will all be options (literally). Davis is already sent down. Nicasio won't be waived. I doubt they will add any relievers to the 40 yet.
Only wild card I see is if the Phillies decide they want a second utility IF and just move on from Altherr. Or make a surprise Williams trade.
