The man sent down to the minors in return for Stephen Strasburg being called up to the majors will be taking the mound for Washington this Tuesday in Atlanta.
Bill Ladson reported from Twitter that he just found out RHP Craig Stammen, who was optioned by the Nats to Triple-A Syracuse on June 6 after starting against the Cincinnati Reds in a no-decision extra inning loss, will return the 25-man roster and join his team on the road for the Braves series.
Stammen was 1-2 with a 5.43 ERA in 12 starts with the Nationals this season.
