Sanchez was designated for assignment by the White Sox on Monday, Scot Gregor of the Daily Herald reports.
Sanchez came up near the end of April with both Kevan Smith and Alex Avila battling injuries. However, with Avila reinstated from the DL on Monday, the Sox will annex Sanchez to clear a spot on the roster. If Sanchez passes through waivers unclaimed, he figures to land back at Triple-A Charlotte.
