Dubon (shoulder) is starting in left field and batting ninth Tuesday against the Phillies, Brian McTaggart of MLB.com reports.
Dubon sat out Monday's contest after he suffered a shoulder injury during Sunday's series finale versus Baltimore, but he's back in action after missing just one game. The 30-year-old hasn't found much success at the plate in August with a .175/.232/.222 slash line through 21 games.
