When the Washington Nationals signed free-agent reliever Rafael Soriano, it looked as if the club had solidified its only clear weakness. With a stellar rotation, deep bullpen and balanced lineup, it's easy to see why many think the Nats are baseball's best team.

One issue seemed to hang over the move, though, and that is the fact that the Nationals don't have a reliable lefty in the bullpen. In the age of lefty specialists, this seems like it could be a major problem. However, the Nats can look to the recent past for a blueprint to follow.
