Jonah Cox jumped from Double-A to the SF Giants in 2026, bringing elite speed and defensive versatility while facing a steep adjustment at the plate.
San Francisco Giants rookie Jonah Cox emerged from Double-A to claim a major-league role during the 2026 season. After hitting .400 with 27 stolen bases in 44 games for Richmond, Cox earned a direct promotion to MLB on May 31, making his debut against the Colorado Rockies at Coors Field.
