2005: Chad Cordero
In the team's first season back in Washington, Chad Cordero was nothing short of extraordinary. In the best season of his career, Cordero tied a major league record for saves in a month when he recorded 15 during June. He was one of two Nationals to be named an All-Star and struck out the lone batter he faced in the game, Ivan Rodriguez. "The Chief" finished the year with an MLB best 47 saves.
