Who do I go with SP's? WHIR!!!

I'm in a weekly lineup, 12-team roto (standard stat + Holds/OBP) keeper league. My lineup is due soon and I'm having a hard time if I should plug one of (if not both) my two start pitchers this week in Johnny Cueto (vs. NY Yankees - @ Baltimore) and Chris Narveson (vs. Tampa Bay - vs. Minnesota). My question is, if I do, who do I bench?

Zack Greinke - vs. Tampa Bay
David Price - @ Milwaukee
James Shields - @ Houston
Justin Verlander - vs. Arizona
Jordan Zimmerman - @ Chicago White Sox

Thoughts? Right now, I'm leaning toward Cueto over Zimmerman, but playing the Yanks has me a bit nervous. Thoughts? WHIR as always!
