He joined Cordero and Ryan Zimmerman as the third member of the Nationals franchise to be called up to the major leagues in the same year that he was drafted. Detwiler opened the 2009 season with the Harrisburg Senators of the Class AA Eastern League. However, due to the injury of Scott Olsen, he was called up to start on May 18 against the Pirates. He went 5 innings and allowed 3 runs, striking out 6.
