Your infield isn't terrible if Chavez is healthy. Posada is fine. ( I can tell your a yank fan by your team), your OF is a little weak but Swisher could be fantastic but Ordonez and Hunter are never better than average. Jim Edmonds is always injury prone too.
If you can drop Crosby for a better SS or hitter. He is always injured and isnt worth a roster spot.
Your pitching isnt't that bad and your taking some good risks with Zito and D-Mat. See if you can do better than Kerry Wood and DEFINTLEY DROP MARK PRIOR AS YOU ARE READING THIS, add someone from the WW if possible.
Drop proctor for a prospect or a darkhorse closer canidate. Relievers except Zumaya should not be on a roster unless they could possibly become the teams closer.
John Patterson is a good find. For your wavier wire replacements, see if guys like a Dave Bush or Kelvim Escobar is available, as those are common guys who will be good who dont get drafted.
