DETROIT (AP) - Philadelphia left-hander Cliff Lee has been scratched from Saturday night's start at Detroit because of a stiff neck.
Lee will be replaced by left-hander Raul Valdes, who has gone 1-0 with a 7.59 ERA in 11 relief appearances this year.
Lee is 10-4 with a 3.05 ERA.
Detroit's Max Scherzer puts his 14-1 record on the line Saturday.
The Phillies are already without right-hander Roy Halladay, who is on the disabled list along with first baseman Ryan Howard and outfielders Domonic Brown and Ben Revere.
