Jayson Werth, one of the few Nationals who knows from experience how to win in October, stood at his locker yesterday afternoon and listened as a reporter told him the news of day: Davey Johnson had just said Stephen Strasburg would make his final start Sept. 12. Werth pulled his cell phone from his pocket and looked at the date. "Two starts?" he asked. Two starts. Werth though for a moment, and then delivered one of the more thoughtful, level-headed takes about the Strasburg shutdown any player has shared.
