The zone rating counts every ball hit to his part of the field while he played there, his club’s positioning included; Savant OAA uses his actual starting spot and is the better individual grade. They agree best in the outfield. See the model card.

Contract & projection

Club control (RosterResource) · Keystone projected WAR

2027 0.1 WAR Pre-arb (est.) $780K*

2028 0.0 WAR Arbitration (est.) $1.2M*

2029 −0.1 WAR Arbitration (est.) $1.3M*

2030 −0.3 WAR Arbitration (est.) $1.3M*

* Estimated: RosterResource has no contract row for him, so control through 2030 estimated from his MLB debut (2024-09-08): 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.
