Rookie Ian Kennedy, who is 1-0 with a 1.89 ERA after three starts in the majors, has been scratched from tomorrow's start against Toronto with what the team is calling a muscle strain in his upper back.
Since the team has been using six starters, the others will move up a day: Roger Clemens vs. Shaun Marcum tomorrow, Phil Hughes vs. Dustin McGowan on Sunday and Mike Mussina vs. A.J. Burnett on Monday.
