Report: Marlins to sign Giancarlo Stanton to 13-year, $325 million deal

The Miami Marlins and outfielder Giancarlo Stanton have a deal in place that will pay Stanton $325 million over 13 years, sources tied to the team told Jon Heyman of CBS Sports on Monday.

The deal will also give Stanton an early opt-out clause and a no-trade provision. According to Heyman's sources, Stanton, 25, would be able to invoke the opt-out clause soon after he turns 30.

The deal exceeds Alex Rodriguez's $275 million contract with the New York Yankees, signed in 2008. Stanton's deal would be the largest in American sports history.

Stanton just completed his fifth season with the Marlins, batting .288 with an NL-leading 37 home runs this year. He also had 299 total bases, 105 RBI, 24 intentional walks, and a .555 slugging percentage. He has led the NL in slugging percentage twice, this season and in 2012.

He also finished second to Dodgers' pitcher Clayton Kershaw in MVP voting.

The team, Heyman writes, has been working to shed its reputation as a franchise unwilling to spend money. Miami entered the 2014 season with a $47 million payroll, the second-lowest in the league, behind the Houston Astros.

Once this deal is finalized, the team's future payroll obligations will rise by more than $300 million. The $325 million salary would be more than the Marlins' 2009-2014 payrolls combined.

Heyman reports that the Marlins are expected to hold a press conference "in the middle or later part of this coming week, perhaps Wednesday or Thursday."
