With the signing of Rafael Soriano, the Nationals have exceptional righthanded bullpen depth: five relievers who last year had ERAs no higher than Tyler Clippard's 3.72. But that arsenal is not matched from the left side. With Sean Burnett and Tom Gorzelanny leaving through free agency, the team had Zach Duke battling a host of nonroster invitees in camp for bullpen roles. Rather than force an unqualified pitcher like Fernando Abad or Bill Bray onto the roster, manager Davey Johnson should run a bullpen without a lefty specialist. His top returning relievers, Clippard (against whom batters had a slash line of .200/.286/.357) and Drew Storen (.218/.284/.316) have been excellent against lefties. Duke, a starter for most of his eight-year career, can be reserved for long relief, and Johnson can get away from hyperspecialization. It's a very 1980s idea: Put your best pitchers on the mound and let them do their jobs. Johnson should know. Before matchup baseball became the norm, his Mets won the 1986 World Series with just such a bullpen.
