Why he's available: No one's saying he is yet. As long as the Rockies are within seeing distance in the National League West -- which, as was proven last year, can turn around in a hurry -- he's going nowhere, and the Rockies know they have a year and a half to negotiate toward a long-term deal.
Will he go? It all depends on how close the Rockies feel they are at the Deadline; remember, they were eight out last July 1 but cut it to 3 ½ by the deadline, so there's plenty of time for that decision.
Where might he go? A large-market team would have to be willing to give up at least two of its best young players, and a veteran leader wouldn't be a bad throw-in.
Why he's available: Dunn is playing out his $13 million option and can become a free agent after the season. Also, a full no-trade clause provision expires/expired on June 15 and becomes limited to 10 teams of his choosing.
Will he go? If the Reds decide they're not contending, possibly. If they're still in the hunt, no. Dunn is also a favorite of owner Bob Castellini.
Where might he go? Dunn is a perfect fit as a DH for an American League club, or the Red Sox may have an opening for a big bat. Nationals GM, and former Reds GM, Jim Bowden has long been a fan of Dunn and could be a pursuer.
Why he's available: Griffey has hit his 600th home run and is a potential free agent after the season. He's also made overtures that he'd like a chance to play for a World Series contender.
Will he go? Unlikely. Griffey owns 10-5 rights and can veto any trade. He also has a $16.5 million club option for 2009 that he'd likely demand to be picked up for him to approve a deal.
Where might he go? Cubs, the Mariners ... Griffey could be reunited with former Seattle manager Lou Piniella and have a chance to play for a contender. In the past, he has not dismissed the notion of playing in Chicago. The Cubs also are a good bet to be in the postseason. Once heavily rumored, the Mariners' massive struggles have likely diminished any chance that Griffey would return to his original team, at least during this season.
Why he's available: With one season left on a four-year deal, this would be the time to ship Bay off and make sure the organization can get more than adequate return in exchange for the left fielder.
Will he go? While it remains a strong possibility, Xavier Nady being traded may alter things. However, if the Pirates are out of contention, trading both corner outfielders isn't inconceivable.
Where might he go? Bay nearly went to Cleveland in a Winter Meetings trade and that still seems to be his most likely destination.
Why he's available: Torii Hunter's presence and a glut of outfielders make one of the game's best defensive center fielders available if someone wants to pick up three-plus years on his five-year, $50 million contract.
Will he go? Not likely. He's still a productive player, and the Angels won't give him away.
Where might he go? Padres are a perfect fit, in need of true CF and leadoff man. Would be a nice fit with the White Sox.
Why he's available: He's 32, and Oakland has plenty of younger and cheaper outfielders with far more potential.
Will he go? The A's aren't actively shopping him, but if someone needs a decent run producer with questionable defense and instincts, he can be had for a song.
Where might he go? To any team looking for an injury stop-gap or a solid fourth outfielder.
Why he's available: He's a free agent after the season.
Will he go? Probably not. The Rangers would have needed to fall completely out of the race.
Where might he go? He needs to have the DH spot as an option because of his fragile health.
Why he's available: Despite his power potential and the fact he has played well when put in the lineup regularly, he hasn't been a good fit for the current Rays team.
Will he go? If the Rays manage to obtain an everyday right fielder, they would probably look to unload Gomes.
Where might he go? To any team lacking power.
Why he's available: The Red Sox have a rising center fielder in Jacoby Ellsbury, making Crisp more of a luxury on the team than a necessity. Crisp is also an affordable player with Gold-Glove skill defensively and a speedster on the bases.
Will he go? More than likely, yes. Crisp could serve as a means for the Red Sox plug another area on the team, such as bullpen depth. And the Red Sox have outfield depth in the organization to replace him, including Bobby Kielty and Brandon Moss.
Where might he go? The Cubs, White Sox, A's and Padres have all been rumored to be potential landing spots for the 28-year-old Crisp.
Why he's available: As a veteran outfielder, Payton is not in Baltimore's future plans.
Will he go? Trade or not, Payton will be a free agent next year and isn't likely to return.
Where might he go? Any team -- perhaps the Cubs or Mets -- that needs a vet outfielder.
Why he's available: The Tigers have a newfound abundance of young outfielders coming up through their farm system, and Thames is a second-year arbitration eligible.
Will he go? The Tigers have listened to offers on him the past couple offseasons without much interest, so probably not, though deadline deals could be different.
Where might he go? Teams needing a right-handed power bat off the bench can apply here.
Why he's available: He needs at-bats and can't find them in a loaded outfield.
Will he go? Only if someone makes a reasonable offer.
Where might he go? Giants, Padres, Blue Jays, Twins ... anybody in search of a power bat.
Why he's available: He slumped early, the Rockies have other center-field options, and he has postseason experience.
Will he go? His speed on the bases and his defensive talents -- can cover center at Coors Field and has a good arm -- give the Rockies pause, but outfield is a position of strength.
Where might he go? Any team in need of a leadoff man would be wise to call.
Why he's available: He's probably not, but if he is, it's because there are concerns that he may never fulfill his immense potential as a five-tool player and he could land a ton in return.
Will he go? Out of the group of Kemp, Russell Martin, Clayton Kershaw, Chad Billingsley and James Loney, Kemp is the one who seems to raise the most internal dissent about his future.
Where might he go? Not hard to find a club in need of a young offensive player, but the low-payroll franchises like Washington and Florida would be high on the list.
Why he's available: He's not really, but if he's likely their only chip should a deal for a premier starting pitcher (Erik Bedard, C.C. Sabathia, Aaron Harang) come to fruition.
Will he go? Highly unlikely.
Where might he go? Seattle, Cleveland, Cincinnati.
Why he's available: A power-hitting platoon option in the outfield, Ross is making $390,000, but he is up for arbitration after the season. The team could replace him with prospect Cameron Maybin, who is making progress of late at Double-A.
Will he go? In all probability, Ross remains a Marlin. But for pitching or catching help, he is a chip the Marlins could use.
Where might he go? Conceivably could go to a contender elsewhere is a mid-level trade that helps both clubs. Can play all three outfield positions. Perhaps the Dodgers, where he's played before.
Why he's available: Erstad is a versatile veteran who can play first base and all three outfield positions. He signed a one-year contract with Houston for $1 million and could draw interest from teams looking for a solid hitter and defensive weapon.
Will he go? Erstad may bring the highest value back to the team, but the Astros may be hesitant to deal him. They may want to keep him and re-sign him in the offseason.
Where might he go? Possibly a National League team, who would benefit from having Erstad to pinch-hit and enter games as a defensive replacement at three positions.
Why he's available: Blum is another veteran who is relatively inexpensive and could provide insurance off the bench.
Will he go? Blum has been dealt at the deadline before, and it could happen again. He can play all four infield positions and has a reputation of coming through in the clutch.
Where might he go? If the Dodgers are looking for infield help, they may want Blum.
Why he's available: Gwynn is blocked this season by a set outfield of Ryan Braun, Mike Cameron and Corey Hart.
Will he go? Gwynn would have been traded to Texas last July had the Rangers agreed to a deal for Eric Gagne, who instead went to the Red Sox. The Brewers are certainly open to offers for the athletic, speedy outfielder who can man all three spots.
Where might he go? The Brewers drafted Gwynn in 2003, one spot before San Diego's pick. He could be a great fit for his dad's old team, which plays in spacious PETCO Park and will probably go into rebuilding mode.
Why he's available: He's likely not being shopped, but somebody has to go to make room for Colby Rasmus.
Will he go? Unlikely. Schumaker is considered a key piece of a team in contention.
Where might he go? Too early to tell.
Why he's available: He may not be, but with the Cardinals needing to sort out their 2009 outfield, moving Duncan might be an option.
Will he go? Probably not, but it was also hard to imagine him being optioned.
Where might he go? To the American League, where he could serve as a DH and just work on his impressive power-and-on-base offensive package.
