Jayson Nix has been designated for assignment by the White Sox, according to Joe Cowley of the Chicago Sun-Times (via Twitter). The move clears a spot on the roster for the 21-year-old Dayan Viciedo, who Baseball America ranked as the 61st-best prospect in baseball before 2009.
Nix displayed some power for the Sox in 2009, homering 12 times in 290 plate appearances. His performance this year has been disappointing though, as he hit just .163/.268/.245 in 57 big league plate appearances. In a second tweet, Cowley adds that Nix would like another shot at the majors, but if he clears waivers, his first choice would be to remain a White Sox.
