The Pirates have signed outfielder Antoan Richardson to a minor league deal, according to Jon Heyman. Richardson is a speedy, defense-oriented player who, at age 32 now, has gotten only 20 at-bats in the majors, mostly with the Yankees in 2014. In the minors, Richardson has a history of drawing boatloads of walks, leading to a .395 career OBP in 951 games. His career slugging percentage is just .346. He also has a history of stealing a lot of bases, but that may be impacted by back surgery that kept him out for most of the 2015 season. In his last semi-full season, he put up a fairly typical, for him, line of 271/380/364 with the Yankees' AAA affiliate in 2014.
Most likely, Richardson will be the 2015 version of Gorkys Hernandez (who recently signed with the Giants), giving Indianapolis a good defensive outfielder. How much he plays, though, may depend on how much time Keon Broxton sees with the Pirates.
