Johan Oviedo has been diagnosed with a flexor strain and will be shut down from throwing for six weeks. The Red Sox right-hander has avoided surgery but faces a significant recovery timeline.

The Game Network — Where History Is Kept

Oviedo required Tommy John surgery in fall 2023 and missed the 2024 season plus part of the 2025 campaign. He started the 2026 season with diminished velocity and was placed on the 15-day injured list with a right elbow strain before receiving the flexor strain diagnosis.

The pitcher posted a 3.57 ERA with 2 wins and 1 loss in 9 games for the Pirates during the 2025 season. His performance showed promise following his return from Tommy John surgery recovery.

The Red Sox acquired Oviedo during the 2025 offseason as part of a three-player package, trading prospects including Jhostynxon García. Boston made Oviedo a key piece of their offseason plans, with the pitcher having two years of club control at the time of the trade.
