The Giants have begun talking with Buster Posey's representatives about a potential mega-deal, Jon Heyman of CBSSports.com reports. Jeff Berry of CAA Sports represents Posey, who will earn $8MM in 2013 as a first-time arbitration eligible player.

There’s a “decent-sized gap” between the Giants and Posey’s representatives, Heyman reports. Neither side has given up, however, and the possibility of a long-term deal still exists. Heyman suggests that Posey would like to sign for ten years or more, adding that the Giants aren’t opposed to this notion. It’s possible the Giants will simply sign Posey through his arbitration years, Heyman reports. First the team will see if there’s a fit long-term.

Posey, a super two player, will go to arbitration three more times. If he doesn't sign a long-term deal, he'll be eligible for free agency following the 2016 season. Still just 25, Posey has two World Series titles, a Rookie of the Year award and an MVP on his resume. In parts of four MLB seasons he has a .314/.380/.503 batting line.

A ten-year deal that begins in 2013 would buy out six free agent seasons and would cost well over $100MM. Buster Olney of ESPN.com has suggested Joey Votto's 12-year deal could provide a framework for the Giants and Posey. Ken Rosenthal of FOX Sports recently estimated that adding a seven-year, $120MM deal to Posey's 2013 salary could work for both sides.
