Why he's available: He'll be arbitration-eligible in the offseason, the A's don't like to pay big money for closers, and Oakland's bullpen is well-stocked with good, young arms.
Will he go? For the right price, sure.
Where might he go? Arizona might be interested. The Brewers would be a good fit, too.
Why he's available: Sherrill has been huge as a closer, which could net a huge return.
Will he go? Baltimore will gauge league-wide interest, potentially expanding the Bedard haul.
Where might he go? To any team that needs a lock-down reliever late in the game.
Why he's available: Bradford has playoff experience and may have more value in another city.
Will he go? As the season progresses, Bradford's chances of moving should only increase.
Where might he go? To a team that needs one final piece in its bullpen.
Why he's available: Walker has postseason experience and is a strong mentor with young pitchers.
Will he go? Walker isn't pitching well and recently returned from injury, which may limit Baltimore's potential return.
Where might he go? The field is wide open for the southpaw specialist.
Why he's available: Emergence of Jose Arredondo and Darren O'Day give club depth in middle relief, and Kelvim Escobar could be back.
Will he go? Good chance if someone wants a quality arm in middle relief who can spot start.
Where might he go? Tigers, Rangers, Indians all could use him.
Why he's available: Pat Misch was dropped from the pitching rotation, but the Giants may want to keep the lefty on the active roster as a long-reliever. If they keep him, someone, possibly Taschner, would have to go.
Will he go? He's been one of the Giants' most consistent relievers all season, as evidenced by his sub-3.00 ERA. He's attacking the strike zone aggressively and might be able to net the Giants a decent prospect.
Where might he go? The White Sox are sitting pretty atop the AL Central, but their bullpen is bereft of any lefty relievers. The Phillies, too, are leading their division but are lacking in southpaws.
Why he's available: Heilman has grown a bit out of favor with Mets fans after an inconsistent start to 2008.
Will he go? Only if the deal is right. The Mets control Heilman through 2010, and still consider him an important bullpen piece.
Where might he go? Any team looking at Heilman has to consider his desire to convert back to a starting pitcher.
Why he's available: The organization's top pitching prospect could move in a blockbuster rather than a rent-a-player.
Will he go? Possibly.
Where might he go? Seattle and Cleveland may have a possible big-ticket pitcher to deal, and could be looking for prospects. Just Carrasco wouldn't land Sabathia or Bedard, so the Phillies will have to come up with a package of players.
Why he's available: Making $2.5 million with another year of arbitration ahead of him, he is close to being out of team's price range. Converted to a closer in '07, he is a veteran who also can pitch in any role. He's been a spot starter and long relief.
Will he go? If the Marlins are out of it, he would be an attractive trade part to teams looking for an experienced arm. If the team is in it -- and they think they will be -- he probably would stay.
Where might he go? Gregg was obtained from the Angels, and he's pitched for Padres manager Bud Black. Since all teams are constantly looking for relief help, any club in it would be a candidate.
Why he's available: It doesn't look like the Braves are looking to pay him beyond this season and as a left-handed reliever, he could be a desirable piece on the trade market.
Will he go? If the Braves are out of contention, they'll push hard to move him to a contender.
Where might he go? The Diamondbacks and Brewers are among the many contenders who will be looking to add a left-handed reliever.
