Marlins have begun “preliminary” extension discussions with slugger Giancarlo Stanton

The Marlins have already engaged in preliminary contract talks with Giancarlo Stanton’s agent regarding a long-term contract.

No firm timeline is in place, but the organization is hopeful of eventually reaching an extension with their two-time All-Star right fielder.

Marlins president of baseball operations Michael Hill said Sunday on MLB Network Radio that he would like to get Stanton signed by the Winter Meetings (December 7-11), but Hill backed away from that Wednesday on a conference call: “Our negotiations, we want to keep them private,” said Hill. “We don’t want to negotiate this through the media. I will say that we’ve reached out to his representative and that negotiations are ongoing. … We haven’t given him a time line.”

Stanton made $6.5 million this past season in his first year of arbitration eligibility and he’s due a big raise heading into 2015. Locking the slugger up at this point — with free agency just two years away — will likely cost north of $200 million. Frisaro expects negotiations to “heat up” around next week’s GM Meetings.

Stanton, 24, batted .288/.395/.555 with 37 home runs and 105 RBI across 145 games in 2014.
