I'm in a league with 7 bench spots and no innings cap. 6x6 roto w/ L and OPS as the extra cats. I have 6 starters, but could probably use one more to keep pace in W and K with the rest of the league.

SP: Hamels, Haren, Shields, Latos, J Zimmermann, and Masterson.
RP: Marmol, Madson, FrankFrank, and Walden.

Players that I'd be willing to part with in a trade for a pitcher are: Lind, Cozart, Moose, Hill, Cepedes, Morrison, Beltran.

Would Liriano be a decent target to get with one of these players? He seems to be making steps in the right direction. Sometimes it takes guys a couple of years to get their mojo back after TJ.

If you don't like Liriano, what are a few names that I should target as a 7th starter?

I wouldn't trade for Liriano...

Not sure what pitchers are available for you to target. But instead of gambling on a seventh starter, pick up an elite middle reliever and/or start a Hodgepadre at home.
