The Washington Nationals are not a good baseball team. This is no secret. They are an MLB-worst 11-25, and on pace for just 50 wins this season (that's 112 losses!) They've been outscored 235-192 (which, surprisingly, isn't that bad -- they have the 5th best team batting average in the majors), but a team ERA of 5.76 -- the worst in the bigs.
And if they kept scoring systems for grounds crews (I'm guessing Bill James has already developed this: VORGC), the Nationals would probably rank last in that too after this weekend's display.
