Sheets, Sabathia, Young, and Hill, should be fine. I don't agree that you need an ace but you project far below the IP maximum. You can't really count on anything from Pedro at this point. I like Neshek as well but I think you have to consider dropping him for the best SP available or consider using that spot to rotate in spot starters.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
