The Nationals recalled Adon from Triple-A Rochester ahead of his scheduled start Sunday against the Red Sox in Washington.
While making his MLB debut Sunday, Adon will be looking to play spoiler against the Red Sox, who can secure a wild-card spot with a victory over Washington. Adon arrives in Washington having little high-level experience in the minors, as he made just one four-inning start at Triple-A before receiving his first big-league call-up. The 23-year-old righty will likely have a short leash Sunday.
