Miami does not have any intention of selling as the July 31 trade deadline approaches. But according to CBS Sports' Jon Heyman, Mike Dunn and Martin Prado are among the Marlins who will likely draw a notable amount of interest over the next few weeks.
At 30-41 and set to begin a lengthy home-stand, the Marlins are hoping to get as close to five hundred as possible prior to the All-Star break. Jose Fernandez is set to return on July 2 and Justin Nicolino and Jose Urena have both pitched well. The Marlins' rotation has become more consistent as June has progressed and the offense has produced as a result of the success of Dee Gordon and Giancarlo Stanton. Derek Dietrich and Justin Bour have both contributed since being promoted and Christian Yelich and Adeiny Hechavarria might be poised for big second halves.
While several veterans could be considered by contending teams, Prado and Dunn are likely expected to be evaluated closely because of their experience. Prado has emerged as a consistent third baseman who can hit anywhere in the lineup and Dunn has proven to be a valuable left-handed reliever who can also retire right-handed hitters out late in games.
Prado, 31, was acquired from the Yankees and was batting .272/.311/.370 to complement four home runs and 24 RBIs before being placed on the disabled list with a shoulder injury. Prado is under team control next season too, and since the Marlins do not have a notable amount of third base depth, he most likely will not be traded. However, Dietrich has proven he can play third base and gives the Marlins an additional left-handed bat in the lineup. As a result, if the Marlins can find or create the right deal, Prado can be dealt.
Miami may be inclined to trade Prado because of Dietrich's success and Dunn can similarly be traded since the Marlins' rotation will be crowded once Fernandez, Jarred Cosart, and Henderson Alvarez all return. Dunn has posted a 4.81 ERA and 3.80 FIP over 24.1 innings this season and has been the Marlins' primary left-handed relief option late in games. Brad Hand could be in a position to fill the role, though, potentially making Dunn expendable.
In any deal, the Marlins will likely request offense or additional pitching depth in return. Although no deal is close, Miami's veterans may be involved in trade rumors over the next few weeks.
