Gage Jump Velocity Drop Raises Fatigue Concerns for Athletics
AthleticsSignal confidence 70%

Athletics starter Gage Jump has seen his fastball velocity fall roughly 2 mph, a drop manager Mark Kotsay publicly acknowledged. Kotsay noted that Jump spent last season in the minors pitching every sixth day, leaving him unaccustomed to a standard MLB rotation workload. The team plans to review his between-start work regimen as a potential contributing factor. While not a formal injury designation, the velocity decline and fatigue signal represent a meaningful performance risk.
