Royals claim Sierra off waivers from White Sox

SAN FRANCISCO (AP) Making a rare 40-man roster move in the middle of the World Series, the AL champion Kansas City Royals claimed outfielder Moises Sierra off waivers from the Chicago White Sox on Saturday.

To clear a roster spot, the Royals designated right-hander Liam Hendriks for assignment. Hendricks was acquired from Toronto on July 29 with catcher Erik Kratz for third baseman Danny Valencia, and he has not played since Sept. 23.

Sierra hit .230 with two homers and 22 RBIs this year for Toronto and the White Sox.
