Come on, it's silly to suggest that no Nats players have performed well enough to merit a bid. if the All Star game was actually about rewarding players for their first half performances on the field, the Nats would have several players that are more than worthy.
JZim
Strasburg
Soriano
Storen
Rendon
LaRoche
It's just a popularity contest. When players that have been injured all year are voted in ahead of players who are actually playing, the process is to flawed to take seriously.
Being an "All Star" is basically indicative of nothing.
