J.D. Martinez will not opt out of his contract with the Boston Red Sox, sources told ESPN's Jeff Passan.
By remaining with the Red Sox, Martinez can earn $62.5 million over the next three years. He also has an opt-out clause after the 2020 season.
Martinez, who joined the Red Sox before the 2018 season, slashed .304/.383/.557 with 36 home runs and 105 RBIs this past season.
