The White Sox will call up Wilson Valdez from Triple-A Charlotte today.
The 26-year-old shortstop, who hit .299 in 69 games at Class AAA, will start against left-handed pitching for the rest of the season. Jose Valentin will now be a platoon player, starting at shortstop only against right-handers. Valdez doesn’t have much pop, but does have some speed on the basepaths.
