Yahoo Sports reports: Royals first baseman Vinnie Pasquantino had surgery Sunday on a fractured hamate bone in his right hand and could miss up to six weeks, the latest injury misfortune to befall a club that has struggled to live up to expectations this season. The Royals recalled outfielder John Rave from Triple-A Omaha to replace Pasquantino on the roster ahead of their series finale against the Astros. Jac Caglianone, who has been their regular right fielder, likely will play the majority of games at first base.
