If there are no further rain outs, the Nats will need a 6th starter on Saturday, so that's Hellickson (or Voth or Ross). Stras today, Max tomorrow, Jeffry on Friday, then #6 on Saturday before we bring Fedde or Roark on normal rest Sunday.
For Saturday, I'd like to see Joe Ross start, go 3 innings or once through the order, then Hellickson back him up like the Rays.
