Machado was a superstar in Baltimore.

A league source told the MLB, the deal is $300 million for 10 years. It’s the biggest free-agent contract in history of American sports by average annual value, surpassing the 13-year $325 million deal that Giancarlo Stanton signed with the Miami Marlins in the winter of 2016.

The 26-year-old Machado spent his first six and a half seasons in Baltimore before the Orioles traded him to the Dodgers prior to the trade deadline last year in exchange for prospects Dean Kremer, Yusniel Diaz, Rylan Bannon, Zach Pop and Breyvic Valera. Machado, a career .282/.487/.822 hitter, joins a Padres team that ranked 28th in the league in hitting last year with a .235/.380/.677 slash line as a team.

Prior to this deal, the Padres total payroll for the upcoming season checked in at $80 million with $20 million of that being accounted for by last winter’s big free agent signing, Eric Hosmer. Combined, Hosmer and Machado will make up $50 million of the team’s $110 million payroll.

Machado will make his return to Baltimore in June when the Padres visit Charm City for a two game set on June 25 and June 26.
