“I think that was unfair to begin with,” Manager Davey Johnson said.

Johnson will make sure Peacock’s next appearance comes in a more typical manner. Peacock will not relieve Strasburg tomorrow, in Strasburg’s second start back from Tommy John surgery. Instead, Peacock will continue preparation to make his first career major league start next week in New York against the Mets.

The Nationals have listed their probable pitchers for Sunday through Wednesday, starting tomorrow, as Stephen Strasburg, Ross Detwiler, Chien-Ming Wang, Tommy Milone and John Lannan. But that is likely to change.

The Nationals will need to squeeze in one extra pitcher in order to give Strasburg a start on five-days rest as they intend. That will be Peacock. He is preparing to start either Wednesday or Thursday in New York. He threw one bullpen session yesterday, and he will throw another tomorrow. So, Peacock will likely push either Milone or Lannan back one day, giving them an extra day or rest.
