The San Diego Padres and infielder Manny Machado have reportedly agreed to a 11-year, $350 million contract extension. The deal, which is the largest free agent deal in American sports history, was first reported by ESPN and confirmed by MLB Trade Rumors, New York Post, Yahoo Sports and MLB.com.

The contract includes an opt-out clause after the fifth season and a player opt-in after the tenth season. Machado, who has been an All-Star in four of his five seasons in the majors, is now set to become the highest-paid player in Major League Baseball.

The Padres have been aggressive in their pursuit of Machado and have been in talks with him for several weeks. The signing of Machado is a major move for the Padres, who are looking to build a championship-caliber team.

The signing of Machado is the latest in a series of moves the Padres have made in the last year to try and build a competitive team. The team has also signed free agents Eric Hosmer and Ian Kinsler, traded for Wil Myers and traded for Chris Paddack.

The signing of Machado is the first major move for the Padres this off-season, and it is sure to be the first of many. With Machado now in the fold, the Padres will look to build a team that can compete for a championship in the near future.
