Miami Marlins outfielder Starling Marte will likely be traded before the July 30 deadline and the San Francisco Giants are "one of the key teams to watch," according to Craig Mish and Jordan McPherson of the Miami Herald.

Marte is set to be a free agent after the season and doesn't plan to sign a new deal with the Marlins despite recently undergoing two weeks of extension negotiations, per Mish and McPherson.

The 32-year-old had been seeking a four-year deal, but the Marlins reportedly weren't willing to go beyond three years and a team option.
