Which SPs do I start?

[KingOfSports]

I'm falling behind this week in my H2H league. I'm 7-5 going against someone else who is 7-5. My team is 7-3 in the last 10 games. Because of trades, I am loosing several players so my pitching schedule is thrown off a bit. Here are some options I'm thinking of.

Thursday:
Peavy @ Rockies

Friday:
Nova @ Mets
Wade Davis vs. Cardinals
Niese vs. Yankees
Morton @ Nats

Saturday:
McClellan @ Rays
Arrieta @ Braves
L. Hernandez vs. Pirates

Sunday:
Leake vs. Indians
E. Santana vs. Dodgers

Would you pick up any of these guys as spot starters? I have 5 moves for the rest of the week so I have some wiggle room.
