Boston Red Sox trade prospects and manage injuries amid playoff push

The Boston Red Sox made several high‑profile moves at the 2026 trade deadline. Shortstop Marcelo Mayer, the 2021 fourth‑overall draft pick, was dealt to the San Francisco Giants for left‑handed reliever Erik Miller. The club also acquired catcher Adley Rutschman from the Baltimore Orioles, sending three top prospects and Carlos Narvaez in return. Rutschman, a former No. 1 overall pick, is on the 10‑day injured list with left‑wrist inflammation and may begin a rehab assignment soon.

Injuries continue to affect the roster. Outfielder Roman Anthony remains sidelined with a finger‑tendon issue, while the Red Sox are weighing the promotion of 20‑year‑old shortstop prospect Franklin Arias amid roster flexibility concerns. Chief Baseball Officer Craig Breslow denied any off‑field problems with Mayer or Anthony, emphasizing that their absences are injury‑related. The team, currently within a game of the AL wild‑card lead, hopes the returning players will bolster its late‑season run.
