This is a quick list I ran though. It does not take into account any options that teams or players hold for next season that could dramatically change this list.
Mark Ross NY In his prime, has a .310 lifetime and got his 5th consecutive 100RBI season. The most well rounded player on the list. He's got power, and great OBP, defense and speed. He can play any position outside of SS/C and really could be a team's emergency SS. He won't ever be MVP of the league, but he will help any team and really has no weakness.
Rich Forbes SCO Starting to show his age but he can still hit and get on base. His L/R splits are among the highest for any 3B in the league.
Heath DeRosa HAR Still young and he has solid ratings across the board, good splits, BE and decent Def.
Brian Maeda LOU - Starting to get a little long in the tooth. While his power and RBI numbers have dropped he is still a has kept up his .308 career average and .390 career OBP.
Norman Freeman HAR - Another player that has lost his power numbers from early in his career, but still can get on base, has an amazing .440 career OBP and had a .457 this season. He obviously played in one of the best hitters park but you can’t ignore those numbers.
Greg Brinkley NY – A speedy 3b/OF that can get on base. He probably won’t be a 30/30 player that he was in season two, but can his speed and power make him a threat.
Bailey Crawford/Bob Widger/Manny Hernandez/Chris Sinclair – A similar group of adequate hitting great fielding players that are great to have. Could start for many teams, or at least be that utility player who gets 300+ ABs because he won’t lose a game for in the field.
Daniel Malone CSP- Showing his age. After his fireman of the year award in season 1 he was merely average, but came back to life in season 5 and still has great ratings.
Joey Diaz CHI Has good ratings, but his stamina probably puts him in the bullpen next season. He could serve as a nice LRA for a number of team looking for bullpen help.
Andre Starr - no longer a closer, but his fourth season of a sub 4.00 ERA is worth a being some team setup man.
Marc Wayne - A journeyman RP that will find a spot in a contenders bullpen.
Ramiro Suarez SCO - Another older pitcher, but he appeared in 79 games and had a 1.24 WHIP and 4.24 ERA. He has the kind of rubber arm that every team needs.
Steve Childers STL – Very similar setup guy to Suarez except he’s much younger, and his L/R splits are not good as Suarez.
Mendy Aoki – After a stellar career as a SP he was moved to the bullpen because of stamina issues. This was his worst season yet, after never having an ERA above 3.76 he had a 6.00 this season. His ratings are still good and I don’t expect another season like that, but his STA/DUR numbers kind of put him in no mans land for a role.
Robin Sullivan LOU – Will be 33 years old and is a solid middle of the rotation SP. He’s pitched 210+ innings every season and has a career 70-53 1.38 WHIP 4.43 ERA. Not a very sexy FA pickup, but if it keeps you from throwing a awful pitcher on the mound every 5th day he is worth the money. Health could be an issue for the owner that wants to do a long term deal.
William Woo Ari – Nothing spectacular about this guy, but he’ll keep you in the game and won’t give up many HRs. Just don’t look for him to be the Ace of your staff.
Kevin Franklin ATL – Might be able to help a team hold down the fort until good minor leaguers are ready, but its starting too look like his incredible season 3 was a fluke.
Rodrigo Johnson RIC – Ratings wise this guy looks like a AAA guy at best, but for some reason he performs adequately. Of all the FA SPs available he might have the best OAV, ERA, and WHIP totals of anyone.
Clay Reese – Might have the best chance of catching lighting of any of the group of SPs on the FA market. Season 4 he was on pace to win the Cy Young Award until an injury sidelined him. He seems like he has usually under performed his ratings though.
Dustin Sutton SLC - Sutton had a tough season 5, it could be the signal the end is close for him but he has had a solid career and one or two more decent seasons would not be out of the question. In seasons 2-4 he won 51 games and he still has good L/R splits and control ratings. Has been a career leader in shutouts and complete games.
