The most interesting team in the trade market may be the Miami Marlins, who are carefully straddling the line between being buyers and sellers. Though many of their players are drawing interest on the trade market, the Marlins are only 8.5 games back in the NL East and could look to add pieces before the July 31 deadline.
According to Joe Frisaro of MLB.com, relievers Steve Cishek and Michael Dunn are drawing strong interest from teams looking for bullpen help, but the Marlins would like to keep both because they are reliable and controllable. Teams like the Tigers, Braves, Brewers, Pirates and Indians could all use relief help and may show interest in Dunn and Cishek, but Miami seems disinclined to deal them at this point.
Another Marlin who is drawing interest is third baseman Casey McGehee, according to Jon Heyman of CBSSports.com, who notes that the Mariners are looking at him as a potential trade candidate. Frisaro writes that the Marlins are likely to keep McGehee because they see him as part of their long-term plans, meaning that he is not on the trade market.
With three of their best assets likely to stay put, the Marlins could look to buy on the trade market, with their current focus on adding a controllable starting pitcher and a second baseman to replace the injured Rafael Furcal. They could also be in the market for relief help, and, according to Clark Spencer of the Miami Herald, have strong interest in Athletics' reliever Jim Johnson, who they came close to acquiring earlier in the season before netting Bryan Morris in a deal with the Pirates.
