How does Marvin Hudson get a playoff assignment? He's the worst umpire I've seen this season, especially at first where he appears to just guess on close plays (and some not so close plays) and usually guesses wrong. He's not much better behind homeplate.
Is he good otherwise and just terrible in Nationals games?
Possibly it's seniority (he's been in the MLB morons-in-blue-crew since 1999).
