The Marlins are considering making a serious run at Rays right-hander James Shields, writes Buster Olney of ESPN.com. The two sides have some natural match-up on a trade because the Marlins could dangle Logan Morrison as part of a package for the right-hander.
Shields drew interest from a number of clubs at the deadline including the Tigers and Reds but the Rays opted to hang on to him instead. Rays executive VP of baseball operations Andrew Friedman says that he would like to maintain the team's pitching depth, but Shields would be a huge trading chip this winter.
Meanwhile, Olney writes that in spite of the speculation about Carlos Zambrano joining up with Ozzie Guillen in Florida, there isn't a lot of momentum behind this within the Marlins organization. The club's opposition to the move has more to do with the way Zambrano's stuff has regressed than his personality history.
