Trade for closer

[FBP]

NL 5 x 5 keeper league. 10 teams.

I have been looking for a second closer to supplement my one closer (Hanrahan). I am first in offense but my pitching has been languishing. I feel like my starters are coming around and another closer will ultimately net me gains in the standings as I am currently 7th in saves. An owner has offered me Casilla $10A and Culbertson $1A for Neil Walker $6B and Lincoln $2A. I hate giving up offense for pitching, but a I am intrigued and would appreciate opinions.

I take that deal. Yes, it's NL Only, but Walker's a stiff. Casilla will close and K quite a few. As for the salaries ... meh, win first.
