If Luis Gonzalez (colorado) is available (or another multi-position player), I'd suggest to picking him up... he'd be very valuable as a backup since he can play alot of positions and he's an everyday player for the Rockies. You could then possibly make room to pickup a backup closer.
For a pitching-dominant squad, I think your batting lineup should be competitve enough and shouldn't hurt your team's overall fantasy stats much.
