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.
Posey, who had the major league's best batting average (.336) to go with 24 home runs and 103 RBI in 2012, already owns the MLB record for largest first-year arbitration settlement at $8 million for 2013.
