Trade Candidates: Starting Pitchers

Roy Halladay's availability changes everything, because teams in search of an ace can target him instead of settling for lesser pitchers. But many arms could be moved in the next 17 days and some could even be traded in August. These pitchers, who could all conceivably be dealt, are ranked from highest 2009 salary to lowest:

• Roy Halladay, Blue Jays – At $14.25MM he's pricey, but he's one of the top pitchers in the game, capable of transforming a team's playoff chances like C.C. Sabathia did last year.
• Javier Vazquez, Braves – The rumors surrounding Vazquez have quieted lately, but he could be moved. He makes $11.5MM this year and next and can't be traded to any Western division team.  
• Gil Meche, Royals – Meche makes $11MM this year and has $24MM remaining on his deal afterwards.
• Doug Davis, D'Backs – The D'Backs aren't impressed with the players the Brewers are willing to offer for their pitcher, who makes $8.75MM this year. Davis has been productive all season.
• Jon Garland, D'Backs – Another solid but unspectacular arm, Garland makes $6.25MM this year. No team acquiring him should count on receiving picks if he leaves as a free agent, because Garland has a clause in his contract that prevents teams from offering him arbitration if he has Type A stauts.
• Cliff Lee, Indians – He makes just $5.75MM this year and the Indians have an affordable $8MM option for 2010, so they'd have to see an awesome offer to part with Lee, who's following up his Cy Young season with another solid year.
• Brad Penny, Red Sox – Now that they've called on Clay Buchholz, the Red Sox once again have a surplus of big league pitchers. At $5MM plus incentives, Penny's affordable this year. 
• Ian Snell, Pirates – He's pitching well in Triple A, where he struck out 17 in one game. The Pirates have tried to move Snell and his $3MM salary.
• Paul Mahom, Pirates – The Pirates have been willing to sell and Maholm's been effective this year. He makes $2MM, and has at least $11MM remaining on his deal after the year.
• Brian Bannister, Royals – At just $1.7MM, he's one of the cheaper starters out there.  
• Carl Pavano, Indians – The Indians aren't contenders and Pavano has pitched better this season than he did in four years with the Yankees. He makes a base salary of just $1.5MM, but that could rise as high as $6.8MM because of incentives.
• Jonathan Sanchez, Giants – He makes less than $500k and, as we found out this weekend, he has the potential to be dominant.  

Let's not forget about some free agent pitchers like Ben Sheets (may be injured), Pedro Martinez (about to sign), Odalis Perez and Paul Byrd.

None of the following pitchers are available now, but they could be if their teams fall from contention: Bronson Arroyo, Doug Brocail, Jason Marquis, Erik Bedard and Jarrod Washburn.
