Which OFs would you trade?

[V]

So... I'm getting really tired of leaving HRs on the bench EVERY day (or so it seems). I've got a wealth of riches right now, but I really would like to deal some OFs for SP help.

I've been playing my OFs based on expected matchups or if I realize a player is sitting for the day (daily league), but I still seem to leave something on the table EVERY day). For example, I sat Werth against Hudson (and lost his HR) and J.Upton (facing Lincecum tonight). Ortiz and Joyce play against right-handed starting pitchers only.

My OFs (we play 4):
Berkman (currently at IF; I have Aaron Hill on my bench and Neil Walker at 2B).
J. Upton
Werth
Granderson
Sizemore
Bourn
Joyce
and Ortiz as my UT

Tonight I have HRs from Sizemore, Joyce, and Ortiz, with 1 from Werth on my bench, an 0-fer from Granderson (against Kyle Davies??) and J.Upton on my bench (facing Lincecum).

So, who has the best combination of trade value and that I wouldn't miss too much? I'm 1st in HRs, 3rd in R/RBIs, 7th in SBs, and 6th in AVG (and 9th/11th/5th/10th/10th in the pitching categories).
