The Kansas City Royals acquired veteran outfielder Randal Grichuk from the Arizona Diamondbacks on Saturday, signaling that the franchise is willing to be a buyer to stay in the playoff hunt. The D-backs added right-hander Andrew Hoffmann, who has made three appearances for the Royals this season out of the bullpen. The 33-year-old Grichuk has played the past 1 1/2 seasons for the D-backs, with the club using his right-handed bat mostly against left-handed pitching.
