Add Dan Haren's pitching to Ryan Zimmerman's hitting, and Washington again looked like a playoff team. Too bad for the Nationals they can't subtract nearly a whole season's worth of muddling along. "The math keeps getting smaller and smaller," Haren said. Haren threw one-hit ball for six innings, Zimmerman hit another home run and the Nationals won their fifth straight game, beating the New York Mets 3-0 on Wednesday in a night full of 9/11 tributes.
