Contract & projection

Club control (RosterResource) · Keystone projected WAR

2027 0.4 WAR Pre-arb (est.) $780K*

2028 0.4 WAR Pre-arb (est.) $803K*

2029 0.3 WAR Pre-arb (est.) $828K*

2030 0.3 WAR Arbitration (est.) $1.7M*

* Estimated: RosterResource has no contract row for him, so control through 2032 estimated from his MLB debut (2026-07-07): six years of service at the earliest; he isn’t in the contract data, and time in the minors would add seasons; pre-arbitration years at the minimum, arbitration years from Keystone’s arbitration model.
