I'm thinking Voth starts tonight if it is played. Originally, this series was supposed to be Corbin Monday, Fedde Tuesday, then Max and Stras, with Sanchez, Corbin, Fedde v. ATL. Slide Max to Friday so it is Max, Sanchez (extra day), then Fedde on long rest, rather than start Fedde today and throwing either him or Corbin on short rest. Fedde can even give you an inning or two in the pen.
Alternatively, if you expect tomorrow to be rained out, you could do Corbin and Fedde today, then Stras, Sanchez, Scherzer v. the Barves, with either Corbin or Fedde Sunday if you don't have rain outs.
