Felix / Granderson trade, which pitcher to add?

[dannahann]

7 x 7 12 team mixed roto keeper (extra cats are H, OPS and HR, Losses)
My pitching staff is poor but I own the best hitting in the league. The clear league favorite owns Lincecum Halladay and Felix along with the best bullpen in our league. His bats can't compete with mine but I still project him to win this league going away, as he did last yr. He offered me Felix yesterday saying it would take Granderson and an OK SP from my staff. The SP I'm thinking of adding include Erv Santana, Ben Sheets, Justin Duchshere, or Francisco Liriano. He prefers Liriano. SP I won't trade in this deal are Lester, Sheilds, and Brett Anderson. Without Granderson my hitting consists of
Mauer, (Salty)
Fielder, Butler
Utley, Callaspo
Chipper, Tejada
Bartlett,
Markakis, BJ Upton, Quentin, Rasmus, Maybin, McClouth
