CHICAGO (AP) Kansas City center fielder Lorenzo Cain has a sore right knee and is out of the lineup for the Royals' series finale against the Chicago White Sox.

The AL Central champions also were without Alex Rios on Thursday night after he was scratched because of a stiff back. Paulo Orlando got the start in center field, and Jonny Gomes was in right.

Manager Ned Yost says Cain and Rios are day to day.
