San Francisco Giants Promote Jonah Cox Directly From Double-A Amid Winless Start

The San Francisco Giants added 24‑year‑old outfielder Jonah Cox to their major‑league roster on June 1, skipping the usual Triple‑A step. Cox was called up directly from the Double‑A Richmond Flying Squirrels, where he was hitting .400 with a 1.097 OPS and had stolen 27 bases.

Giants manager Tony Vitello said he envisions Cox in center field after starter Harrison Bader was placed on the 10‑day injured list with left plantar fasciitis. The move comes as the 2026 Giants endure a historically poor start, posting the league’s worst win‑loss record and losing ten straight games to division rivals. While unusual, the Giants have previously promoted prospects such as Pablo Sandoval and Matt Duffy from Double‑A.

Cox expressed surprise at the promotion, noting teammates drenched him with water in celebration. The organization hopes the speed and defensive ability of the rookie can add spark to a struggling lineup.
