The Washington Nationals have made another roster change in the middle of their four-game road series against the Philadelphia Phillies. After putting James Wood on the injured list and shuffling their bullpen unit, the Nationals made another high-profile move ahead of Wednesday's contest. Per an announcement from the team, they decided to designate right-handed pitcher Zack Littell for assignment as the corresponding move to right-handed pitcher Brad Lord getting activated off the injured list.
