After a week of medical reviews and some reported alterations to the language in his five-year, $110MM contract, J.D. Martinez was introduced by the Red Sox at a press conference this morning (video link via MLB.com). Seemingly, the Lisfranc foot injury that hampered Martinez early in the 2017 season served as enough of a red flag for the Sox that further work needed to be done to sort the matter out. Agent Scott Boras met with reporters following Martinez’s introduction today, revealing that the new contract language includes the addition of a third player opt-out (after the fourth season of the contract) in exchange for some medical protection for the Red Sox (Twitter links via Evan Drellich of NBC Sports Boston and Mark Feinsand of MLB.com). Specifically, Drellich further reports, the Red Sox can convert both years four and five of the contract into mutual options, pursuant to the newly drawn up language. In essence, then, the Sox have negotiated their own means of walking away from the final two years of the contract in the event that Martinez’s foot proves to be a chronic condition. Per Drellich, should Martinez spend 60 consecutive days on the DL in year three of the contract (2020) with an injury related to his prior Lisfranc injury, the fourth year can be converted into a mutual option. Boston could also convert the fourth year to a mutual option should an injury pertaining to the prior Lisfranc issue prompt Martinez miss a combined 120 days between the second and third years of the deal (2019-20), with at least 10 of those days coming in year three. (The Boston Globe’s Nick Cafardo first tweeted that the team could render the fourth year a mutual option.)
