Wily Mo Pena should be ashamed of how he's been hitting. The Nats "meat of the order" (Zimmerman, Johnson and Kearns) have been hitting at or near the Mendoza line, and aren't close to hitting their weight.
All three need to be benched in favor of two Popsicle sticks and a straw.
Seriously though and this needs to be said, Mister Franchise (Zimmerman) needs to wake up to the fact that the season starts at the beginning of April, not in June or July. I'm sorry, but unless the "face of the franchise" gets his act together, he has no business playing at the major league level. He could be prefect with the glove and if he doesn't back it up with the bat, he's useless to the team. The Nats need players who can do the job during both halves of the inning.
IMO, Zimmerman, Johnson and Kearns should be booed off the field and Manny Acta booed along with them for leaving them in there with their useless bats.
