Several contenders might be looking for help at first base, including the Rockies, Angels, Giants, and Rangers.  Potentially available players:

• Prince Fielder, Brewers.  The Brewers are listening on Fielder, though we haven't heard much about interested parties.  Fielder is under team control through 2011, after which point he'll pursue an extension worth well over $100MM.
• Adam Dunn, Nationals.  Dunn is losing patience with the Nationals due to their lack of urgency about an extension, reports ESPN's Buster Olney.  The White Sox have interest in Dunn, who might be forced to fill a designated hitter role for them.  Dunn profiles as a Type A free agent, at least in the National League.
• Lance Berkman, Astros.  Like Dunn, Berkman could technically play outfield for a few months.  Berkman has a full no-trade clause and $8.46MM left on his contract.  He's up to .255/.369/.459 on the season. 
• Derrek Lee, Cubs.  The Cubs should probably consider trying to clear some of the $5.79MM still owed to Lee.  The problem: he's yet to slug .400 in any month this season, and his strikeout rate is his highest in a long time.
• Adam LaRoche, Diamondbacks.  LaRoche is more affordable than those listed before him ($3.51MM remaining), but he hasn't hit much since May.  He's consistently posted big second halves.
• Jorge Cantu, Marlins.  Aside from the 52 RBIs, Cantu isn't having an impressive season.  Even if ownership doesn't require it, clearing his $2.67MM salary is a solid baseball move. 
• Ty Wigginton, Orioles.  Wiggy made the All-Star team with a strong April and May, and he'll be a useful piece for a contender. 
• Mike Lowell, Red Sox.  As we wrote yesterday, Lowell hasn't played the field much and the Red Sox would have to pay his entire salary. 
• Xavier Nady, Cubs.  The Rangers have strong interest in Nady, reported Bruce Levine of ESPNChicago a few days ago.  Nady hasn't done anything offensively this year, but he hasn't played regularly either.  He's got $1.47MM remaining plus performance bonuses. 
• Kila Ka'aihue, Royals.  Ka'aihue, 26, already has 77 walks for the Royals' Triple A club (and a .463 OBP).  Certainly there are teams out there that would like to see how much of that skill translates to the Majors. 
• Russell Branyan, Mariners.  It was an odd acquisition, but maybe Jack Zduriencik feels that he can trade Branyan again for more than he gave up. 
• Casey Kotchman, Mariners.  The Mariners would have to eat most of his remaining $1.57MM to move him now, as Kotchman is a probable non-tender after the season. 
• Lyle Overbay, Blue Jays.  If you like Derrek Lee, you should like Overbay more.  Overbay is having a better year, especially lately, and has $3.12MM remaining.
• Recently MLBTR also profiled the market for catchers, second basemen, shortstops, and third basemen.

If your team is looking for help at third base this summer, we've got players who could conceivably be available for trade:

• Jose Bautista, Blue Jays.  Amazingly, he's the MLB home run leader at the All-Star break.  He's played more right field than third base this year.  Bautista is under team control for 2011.
• Edwin Encarnacion, Blue Jays.  Encarnacion cleared waivers last month, as no team wants to assume the $2.14MM owed to him.  Someone might take a chance on his power if the Jays eat his salary, but he could just be signed after the season given the expected non-tender.
• Mark Reynolds, Diamondbacks.  So far Reynolds is following up his breakout '09 with an even higher strikeout rate and a .214 batting average.  He's owed only $226K more this season, and then $13MM through 2012.  He's not known to be available, but the contract was signed under previous GM Josh Byrnes.
• Miguel Tejada, Orioles.  Tejada isn't hitting much for the O's, and he's still owed $2.71MM plus a $150K bonus if traded and $100K if he reaches 630 plate appearances.
• Ty Wigginton, Orioles.  Wiggy made the All-Star team with strong work in April and May.  He has $1.58MM remaining.
• Jhonny Peralta, Indians.  Peralta has a lot in common with the 2010 version of Tejada. 
• Jorge Cantu, Marlins.  His OBP and SLG aren't great, yet he remains an RBI man.  He's got $2.71MM left and is known to be available. 
• Wes Helms, Marlins.  Occasionally, Helms still shows something against left-handed pitching.
• Alberto Callaspo, Royals.  He's battling a wrist injury, but Callaspo has a decent bat for someone who can handle second and third base, and even shortstop in a pinch.  He'll be arbitration-eligible for the first time after this season.
• Andy LaRoche, Pirates.  He was bumped to a utility role with Pedro Alvarez's promotion, not that Alvarez has fared better in his first month. LaRoche will be arbitration-eligible after the season, though he could be non-tendered. 
• Jose Lopez, Mariners.  Lopez switched from second base this year and has been abysmal with the bat.  He hit 25 home runs last year, and only has $1.29MM remaining on his contract.  He could be non-tendered after the season if his $5MM club option is declined.
• Aramis Ramirez, Cubs.  Aramis usually hits well despite trips to the DL, but this year he was brutal for the season's first two months.  He'd be an interesting deadline pickup, but he has $7.1MM remaining this year, a $1MM assignment bonus if traded, and a $14.6MM player option for 2011.
• Pedro Feliz, Astros.  There's not much left with Feliz, aside from the $2.03MM on his contract.
• Mike Lowell, Red Sox.  He's played only 72.6 innings in the field this year and is owed $5.41MM, so the Red Sox would have to pick up the tab.
• We've mostly discussed offense here, as the defensive samples are so small.  Still, I'll mention that Lopez, Callaspo, and Reynolds have above-average UZR/150 numbers at third base this year. 
• Keep in mind that overpaid players like Tejada, Ramirez, Feliz, and Lowell are candidates to be traded in August.
