Ken Rosenthal of the Athletic first reported that Yamamoto would be able to opt out of the contract after the 2029 and ’31 seasons. According to the Associated Press, that’s in part conditional on the pitcher’s arm health in the first six years of the deal. If Yamamoto undergoes Tommy John surgery or spends 134+ consecutive days on the injured list with a right elbow concern between 2024-29, his opt-out chances would be delayed until following the 2031 and ’33 seasons. In the absence of that significant of an elbow injury, he’d be able to opt out after 2029 and ’31 as initially reported.

Interestingly, the contract also includes an opt-out provision designed to keep him from being traded. The AP reports that if the Dodgers trade Yamamoto, that would vest an opt-out clause that’d allow him to become a free agent at the end of that season. While it’s not true no-trade protection, it makes it very difficult to deal him. Any acquiring team would have to account for the possibility that Yamamoto leaves the following winter.
