The team announced the signing Monday night after Hosmer passed his physical. The first baseman, who spent his first seven major league seasons with Kansas City before becoming a free agent this offseason, can opt out of the deal after five years.

The contract is the largest in Padres history.

Hosmer gets a $5 million signing bonus payable within 30 days of the contract being approved by the commissioner's office. His salary is $20 million each year from 2018 through '22 and will be $13 million annually from 2023 through '25 if he doesn't terminate the deal.

A four-time Gold Glove winner and 2016 All-Star, Hosmer will be introduced during a news conference Tuesday morning at Padres camp in Peoria, Arizona.
