Milestones don't come around often, and this one belongs to Spencer Jones. A first-round pick in 2022 and one of the Yankees' top prospects, Jones made his MLB debut in 2026 after a standout run through the organization's minor league system. This #78 gray jersey was game-used by Jones on June 9, 2026, against the Cleveland Guardians, the night he launched his first career MLB home run, a 443-foot blast to dead center off Slade Cecconi. A great addition for any Yankees fan or collector, this jersey was obtained under the auspices of the Major League Baseball Authentication Program and can be verified by its numbered hologram at MLB.com.
