The Yankees can exercise a fourth-year option in the second year of the deal, otherwise Britton can opt-out if they choose not to extend the pitcher.
When finalized, Zach Britton's deal with the Yankees will be for three years guaranteed, sources tell ESPN. The Yankees will be able to exercise a fourth-year option after the second season. If they don't, Britton will have the ability to opt out following that second year.

The option would push the money to a minimum of $50 million. Britton was expected to be the focus of the Yankees after the Phillies signed David Robertson to be their supposed closer.
Britton finished 2018 with a 2.88 ERA, giving up 8 earned runs and 2 homers. He was a solid option in the bullpen and will get more work this season. He will remain in a rotation consisting of Dellin Batances, Aroldis Chapman, and potentially another signing.
