The Rockies are designating former top outfield prospect Yanquiel Fernandez for assignment, reports Francys Romero of BeisbolFR.com. Between the Fernandez DFA and this morning's trade of right-handed reliever Angel Chivilli to the Yankees (in exchange for non-roster first baseman T.J. Rumfield), Colorado has cleared two spots on its previously full 40-man roster. Fernandez just turned 23 on New Year's Day but has exhausted two of his three minor league option years. He made his major league debut with the Rox this past season but hit just .225/.265/.348 with a 30% strikeout rate in 147 trips to the batter's box.
