Why he's available: He has been hurt a lot of the year and the Rangers are playing well without him. He could be a free agent if his option isn't picked up.
Will he go? If the team determines he hasn't had enough of an impact after coming off the disabled list, then the Rangers might try to move him.
Where might he go? Any team that needs a left-handed bat at either first base or designated hitter.
Why he's available: The Rockies would have to feel as if they're hopelessly out of the race first, then they would have to be comfortable enough with prospect Ian Stewart to explore the market for Atkins -- eligible for arbitration for two more years.
Will he go? Stewart didn't set the league afire early in his callup (while playing second), so the Rockies would have to slump badly for management to make that move.
Where might he go? Atkins is average at third, but he also plays first and can be a designated hitter, so the list of suitors could be large.
Why he's available: He's really not. But if the team precipitously drops in regard to playoff contention, the White Sox might want to get something in return before possibly losing Crede to free agency.
Will he go? No. With all due respect to Josh Fields, who is currently filling in because of an injury to his counterpart, the White Sox are currently a better team with Crede in place.
Where might he go? A couple of West Coast teams could use third basemen, and Crede is the best as far as defense goes. But it's more than likely Crede won't be going anywhere.
Why he's available: Blalock and Chris Davis have been playing more first base than the Cat.
Will he go? He has one year left on his contract, which might put off some teams.
Where might he go? Catalanotto would make a good role player/pinch-hitter for a National League team.
Why he's available: The Orioles don't think he's the long-term answer at first base or DH.
Will he go? His contract may make him difficult to move, but the Orioles will try.
Where might he go? Probably a big market team.
Why he's available: Betemit is an extra part with the Yankees but could conceivably start at a corner for another club. The Yankees liked adding his bat but he's young enough that he could bring back something of value.
Will he go? Brian Cashman seems rather fond of Betemit and the Yankees have given him opportunities to succeed after acquiring him for reliever Scott Proctor. That makes him somewhat less likely to be moved, though the Yankees could promote Alberto Gonzalez and not miss a beat.
Where might he go? Ideally, a smaller market club in need of a corner infielder with some pop and potential. He's too big to play shortstop but can pick it at second base in a pinch and seems to have taken decently enough to first base.
Why he's available: Low-wattage power threat who will be a free agent at year's end.
Will he go? If the Orioles can find a needy playoff contender, Millar will be shopped.
Where might he go? Millar is always a trendy pick to wind up with the Yankees or Red Sox, though the acquisition of Xavier Nady likely takes the Yankees from the equation.
Why he's available: Veteran third baseman won't be around when the Orioles compete next.
Will he go? Mora has a full no-trade clause, which could make him very difficult to move.
Where might he go? Philadelphia might be his best bet, but Mora will likely stay put.
Why he's available: Gload became the expendable part of a first-base glut that now most often features Mark Teahen at the position. There's also Billy Butler, who has torn it up since returning from Triple-A Omaha.
Will he go? A left-handed hitter, Gload is no power blaster but he can plug the gaps. His defense at first base is excellent and he's a gritty plugger who could please any manager.
Where might he go? Gload is not a player who can carry a club but he'd be a valuable fill-in; however, the obtaining club must take on a two-year contract.
Why he's available: Trading Vidro would open the designated hitter spot and allow manager John McLaren to give up-and-coming catcher Jeff Clement more at-bats.
Will he go? Wanting to deal Vidro and finding someone willing to take him could be difficult, but he is a switch-hitter and could provide a quality bat off the bench for a contender in either league.
Where might he go? The Dodgers, Cardinals or Diamondbacks all could use the switch-hitting Vidro as a late-innings pinch-hitter.
Why he's available: Since he is arbitration eligible next season, and he will get a hefty pay raise from the $395,000 he is earning now, the team may dangle him if it can get either catching or pitching help.
Will he go? As long as the Marlins are in the race, it is doubtful he will be moved. Odds remain that he will stay.
Where might he go?Any team looking for first-base help.
