Minor league deals, of course. IIRC, Vlad wanted Martis. Fox has good power but no patience. He owns various gloves that he's been known to wear at times, including a catcher's mitt. UPDATE by Charlie: The Nationals apparently sent Martis back to Class AA in 2011, after a couple seasons in AAA, because they were unhappy with his conditioning. He responded with a much better season. He's still pretty young, and he was one of the best minor-league free agents available. The Pirates also signed outfielder Brandon Boggs (likely Class AAA depth) and infielder Stefan Welch (who will probably be at Class A+ or Class AA).
