Can you imagine having all 3 of those pitchers back? We can only afford to have 1 of those 3 back.
The only pitchers I'm sure will not be back are Speigner and Manning unless both sign Minor League deals with the Nats.
Estrada will start the year in AAA. Hanrahan, Shell, Hinckley, Mock and Rivera are almost guaranteed to be back with the Big team.
They'll probably bring back Colome.
