The Giants have quietly begun talks with All-Star catcher Buster Posey on a "mega-deal" contract extension, according to a CBSSports.com report.
Jon Heyman reports word of a "decent-sized gap" between the Giants and Posey in early contract talks, but the difference is not insurmountable.
Posey, the reigning National League Most Valuable Player, has been a big part of the Giants' two World Series wins in the last three years. The fact that he's 25 years old could lead Posey to seek a deal of 10 years or longer, according to Heyman.
Giants chairman Larry Baer acknowledged last week that the team and its franchise player were already discussing a deal that would cover three extra arbitration years on Posey's current contract. He is scheduled to be paid $8 million in 2013 and becomes a free agent after the 2016 season.
