Pirates shortstop Konnor Griffin sidelined with forearm strain

Konnor Griffin, the 20‑year‑old Pirates shortstop, is dealing with a right forearm muscle strain that will keep him out of short‑stop duties while he completes a throwing progression at Pirate City in Bradenton, Fla. The injury comes as Pittsburgh eyes a push for the playoffs and relies on Griffin’s emerging offensive production.

Rehab plan and timeline

General manager Ben Cherington said Griffin will start a “legitimate throwing progression” at the minor‑league complex before a possible rehabilitation assignment, emphasizing that he must be “100 % asymptomatic” before resuming full throwing duties [2]. Griffin has already been taking batting practice, running bases and fielding ground balls, but throwing was the last activity to return. He resumed light throwing at 75 % effort, reaching 90 feet, and will continue to increase volume and distance over the coming weeks [2].

Impact on the Pirates roster

Griffin’s last MLB appearance was on May 27, and he was placed on the 10‑day injured list on May 31. Although he was technically eligible to return on the Wednesday after that, a second opinion from orthopedic surgeon Dr. Keith Meister led to a two‑week pause from throwing [2]. The Pirates remain at 29‑27 and will face the Minnesota Twins next, while rookie pitcher Jared Jones is slated to return to the rotation, offering some balance to the lineup while Griffin recovers [1].

Performance context

Before the injury, Griffin posted a .261/.322/.394 slash line with an OPS of .716 over 49 games, tallying 47 hits, four home runs and 12 stolen bases in 13 attempts [1]. His speed and emerging power have made him a focal point of Pittsburgh’s young core, and his absence could affect the team’s offensive spark as they chase a postseason berth.

What to watch

• Rehab milestones – Progress in Griffin’s throwing program and any announcement of a rehab assignment.
• Roster moves – How the Pirates adjust the short‑stop spot and whether they call up a minor‑league replacement.
• Team performance – The Pirates’ win‑loss record in the next series, especially against the Twins, to gauge the impact of Griffin’s absence.

Griffin’s injury underscores the fine line Pittsburgh walks between developing its youthful talent and maintaining competitive momentum. The next few weeks will reveal whether his rehab proceeds smoothly enough to keep him on the season’s trajectory.
