Jim Salisbury of CSN. Nix is a 9 year veteran who has played for 4 teams in his career. He hit a career-high 16 home runs with the Nationals last season in 324 at-bats.
The signing of Nix adds a left-handed bat to the outfield mix and figures to be amongst several options for the Phillies in left field. Nix won't play every day but will be a good platoon option against right-handed pitching and could push Ben Francisco out the door. His addition won't have much impact on Domonic Brown, who will still hopefully be given a chance to play in left field regularly.
With the Phillies likely set in the outfield, shortstop has to be next. I would bet that a deal for Jimmy Rollins comes sooner rather than later.
