Bryce Harper will move to center field tonight with Tyler Moore (making his second career start) and Xavier Nady playing corner outfield against Pirates left-handed starter Erik Bedard. Even with Jayson Werth out, the Nationals will continue their pattern of sitting Rick Ankiel against lefties – he has only eight plate appearances against them all year.
