Guillen scratched for at least one game

KANSAS CITY, Mo. -- Kansas City Royals right fielder Jose Guillen was out of the lineup Monday against Minnesota and could miss another game with a stiff left side.

Royals manager Trey Hillman says the stiffness starts in Guillen's lower back and runs up his entire left side. Guillen has been playing through the off-and-on problem, but Hillman decided to give him some time off with the team set to play 15 straight days.

Guillen is hitting .257 with eight homers and 33 RBIs.
