Who's starting on Sunday?

DJ Houlton is now out of the running for the Sunday spot starter position for the Dodgers. He got tattooed for 11 runs (10 earned) in a losing cause for Triple-A Vegas earlier today. Which incidentally, might be good news :).

What options does it lead us with for Sunday? Risk a game with Sele, move Seo a day forward? I would not put Chad Billingsley in a situation where he'd have to be subject to psychological (debut) and physical (three days' rest) pressure at the same time at this point in his  career. Your thoughts?
