Seems like a really solid team to me. But I do agree that you have too much pitching, especially closers -- here are the things I would try:
- package Womack + a RP for an upgrade, ideally to someone who needs steals. Not only is Womack a borderline waiver wire player, but the main category he helps you in is one that you don't need. If you can't get anybody to bite, I'd consider picking up Vidro and stashing him on the DL (if you can spare the room). Vidro should hit in the low .300's and it seems like you could use the BA help.
- Unless there are good SPs available on the FA list, you should probably keep your starters. You've got a little injury risk here, so I wouldn't thin this group out too much. Your trade bait is really with your RPs -- none of them are that great, but in a 12 team league, there will always be a few teams that will be hurting for saves
Once Berkman gets untracked (which he appears to be doing), you will be in really good shape.
