The Nationals have spent the majority ofthis week at the mercy of Mother Nature. As one torrential rainstorm after another has passed through the Washington area, they'vebeen hamstrung. Tuesday, it was a question of getting Stephen Strasburg's startin. Wednesday, they went back and forth with Major League Baseballin attempts to postpone their game with the Los Angeles Dodgersearly, with major flooding and rainstorms pounding the region.Keeping up with the weather was becoming exhausting. "That was the most tired I've ever been in a whole day of doingnothing," manager Davey Johnson said on a rain-soaked Thursdaymorning at Nationals Park.
