Injured Trade Candidates

Players can be traded while on the disabled list, but it rarely happens.  Teams rarely want to acquire an injured player, especially if they're just renting a veteran.  Here are some injured players to watch this month and in August:

• Tommy Hanson, Angels: Hanson should be activated tomorrow after a right forearm strain.  He'd a non-tender candidate in the offseason.
• Ryan Madson, Angels: Madson still hasn't pitched in a big league game since 2011, after complications following Tommy John surgery.  Still, if he looks like the Madson of old on a rehab assignment, he could be a stealthy pickup for a contender next month.
• Jason Vargas, Angels: He had surgery to remove a blood clot and may be back in August.  He could certainly be moved then.
• Aramis Ramirez, Brewers: His knee injury is likely to keep him out until August, but his salary should allow him to clear waivers.
• David DeJesus, Cubs: DeJesus should return this week from a shoulder strain.  He could be moved, but the Cubs do have a club option for 2014.
• Ryan Sweeney, Cubs: Recovering from a rib fracture, Sweeney can't come off the 60-day DL until late August.  The Cubs may prefer to try to re-sign him.
• Franklin Gutierrez, Mariners: The oft-injured center fielder is currently on a rehab assignment, trying to shake a hamstring injury.  The team may not intend to exercise his 2014 club option.
• Mike Morse, Mariners: He may begin a minor league rehab assignment this week as he comes back from a quad strain.  He'd probably be claimed on waivers in August, but could still be dealt.
• Frank Francisco, Mets: Remember him?  Francisco's last minor league rehab appearance came a week ago.  If he gets his elbow right, the Mets could move him in August.
• Jason Marquis, Padres: With a recent right elbow strain, Marquis is an August trade candidate if anything.
• Roy Halladay, Phillies: Halladay, recovering from shoulder surgery, threw a bullpen session recently.  He'd clear waivers in August if the Phillies want to move him, but he'd have to show big league readiness first.  
• Josh Willingham, Twins: Willingham should return next month from a knee injury.  His offensive production has been way down this year, but he is cheap enough to be claimed on waivers in August.
• Jesse Crain, White Sox: He could be back this month from a shoulder strain, and the impending free agent will be well-scouted if so.
• Tim Byrdak, Mets: He's made a dozen minor league appearances on a rehab assignment following September shoulder surgery.
