The streak of bad defense behind Wandy Rodriguez has reached the point of laughter, but only if crying isn't your go-to emotion. Tuesday night at Nationals Park, where Rodriguez's defensive plague came along for the roadie, it was joined by a different and much worse problem: a total lack of offense that sent the Astros to a 1-0 loss to the Nationals. They managed just four hits, two against the dominant lefty Gio Gonzalez, one when he was mercifully pulled for Tyler Clippard and another in an aborted comeback attempt against old friend Brad Lidge as the Astros couldn't get a runner home from second in three tries.
