Mike Pelfrey takes the hill in his season debut tonight against the Nationals. This game represents the Nats' best chance to win this series, as their ace John Patterson will oppose Pelfrey, who has a world of talent but is still plenty inexperienced. This outing will go a long way towards determining whether Pelfrey and the Mets will be able to win a game tonight.
