The most available:
SP Doug Davis - Great middle of the order starter for a competative team missing that one guy
RP Jason Davis - An excellent reliever who can dominate in the top middle relief or setup role, and is still only 28.
RP Scott Linebrink - Like Davis, will dominate in middle relief or setup, and maybe even a closer spot.
RP Mike MacDougal - See Jason Davis and Capps
SS Ron Smithson - Cheap 4.0 spec since he's a bit far away, but good talent nonetheless
1B Guy Harikkala - A decent 1B spec for someone who is looking for a cheap spec to possibly gain talent
2B Josh Barfield - He's whining about being traded, so I thought at least I'd throw him up here. He's pretty cheap if you need a backup infielder.
feel free to inquire about others as well, no one is untradeable
Needs:
Infield prospects (not MLB ready). Especially a 2B wanted, and power would be nice as well
Guys in the mix for the future, and will be hard to pry from me, include:
CF Denard Span
1B Pat Berg
3B Josh Prince
CF Grady Sizemore
SP Humberto Sanchez
CL Joel Zumaya
