There are still options available on the free-agent market, but clubs looking for a “proven closer” have one major option on the trade market to consider:

Former Boston Red Sox and current Philadelphia Phillie Jonathan Papelbon.

Ken Rosenthal of FoxSports.com and others reported in December that the Phillies were looking to move the veteran right-hander, who is still owed $26 million over the next two seasons. It’s going to be difficult for them to move Papelbon in light of the size of his contract, but perhaps they’ll find somebody desperate enough to do business before spring training gives way to Opening Day.

MLB Lead Writer Zachary D. Rymer is here to dish on Papelbon’s trade candidacy, from what’s attractive to what’s not attractive to which clubs look like potential landing spots.
