The Kansas City Royals announced today that the club has acquired right-handed pitcher Vin Mazzaro and left-handed pitcher Justin Marks from the Oakland Athletics in exchange for outfielder David DeJesus. Mazzaro replaces DeJesus on the Major League roster while Marks has been assigned to the Wilmington roster. ?This deal allows us to further increase our pitching depth at the Major and minor league levels,? Royals? General Manager Dayton Moore said. ?Vin Mazzaro fits into our rotation for next season while Justin Marks is a young left-hander who we see starting 2011 at Wilmington. David DeJesus is a high-class person and has been our most consistent performer, both offensively and defensively, over the past few years. We wish the very best for him in the future.?
