The Marlins and slugger Giancarlo Stanton have agreed to terms on a thirteen-year, $325 million contract extension, according to a report from Jon Heyman of CBSSports.com. The deal will to include a no-trade clause and an opt-out clause, and is expected to be finalized soon.
Sources indicate that the opt-out clause is expected to kick in after the 2019 season, when Stanton is 30 years old.
The news of an agreement comes after weeks of public negotiations between the team and Stanton, who finished second in this year's NL MVP voting. The deal will be the largest in baseball history in terms of monetary value, beating out the Yankees' ten-year, $275 million extension with Alex Rodriguez in 2007. Stanton will earn $25 million in average annual value throughout the deal, which is expected to be backloaded due to the outfielder's status as an arbitration-eligible player.
With Stanton in the fold for a long time, the Marlins will likely turn their attention to locking up young stars like Christian Yelich, Adeiny Hechavarria and Jose Fernandez, though reports have indicated that the chances of Fernandez signing a long-term deal are close to nil. The Marlins are also expected to be buyers in this year's free agent and trade markets, and are reportedly targeting veteran starting pitching.
In five seasons with the Marlins, Stanton is the owner of a lifetime .271/.364/.540 line with 154 home runs and 399 RBI. His 2014 season was the best of his career, as he hit .288/.395/.555 with 37 home runs and 105 RBI in just 145 games.
