White Sox acquire minor leaguer Mark Tracy from Rockies for Kenny Williams Jr.

The Chicago White Sox have traded Double-A outfielder Ken Williams Jr. -- son of White Sox vice president Ken Williams -- the Colorado Rockies for Single-A first baseman Mark Tracy, the son of recently-resigned Rockies manager Jim Tracy, reports Daryl Van Schouwen of the Chicago Sun-Times:

The White Sox traded Kenny Williams Jr. to the Colorado Rockies for first baseman - designated hitter Mark Tracy.

Tracy is the son of former Rockies manager Jim Tracy, who resigned after the season.

Williams, 26, hit .250/.321/.388 with four home runs in seventy-seven games at Double-A Birmingham this season. The Rockies actually drafted Williams in the 32nd round in 2007, but the outfielder held out and signed with the White Sox the following year. Williams is a .233/.301/.346 hitter in five professional seasons.

Tracy, 24, was a 22nd round draft pick by the Rockies in 2010. The first baseman and sometime designated hitter hit .264/.310/.448 with six home runs in forty-one games this year at Single-A Modesto.

Neither Williams nor Tracy are top prospects in any regard, but the swapping of front office kin is a quirky move worthy of at least a small note. The trade is also the first for new White Sox GM Rick Hahn since taking over for WIlliams last week.
