Red Sox's Masataka Yoshida Exits Game with Hamstring Injury, Team Awaits Medical Evaluation
August 16, 2026
Masataka Yoshida exited the Red Sox-Pirates game in the third inning with left hamstring tightness after colliding into second base while sliding awkwardly into the bag following a double to right field.
Anthony Seigler replaced Yoshida on the bases and Jahmai Jones took over at designated hitter for the remainder of the game.
Yoshida left the game limping back to the dugout in the top of the third inning as Anthony Seigler replaced him at second base.
The article notes the story will be updated as more information becomes available.
Long-term reinforcement for a potential extended absence includes reinforcements headed to the team: Roman Anthony, Trevor Story, and Isiah Kiner-Falefa are slated to begin rehab assignments in the coming days; Jarren Duran could also be a DH option.
No definitive recovery timeline is provided; further medical evaluation will determine next steps for Yoshida and the team.
Yoshida’s value as a leadoff or middle-order hitter could impact the Red Sox’s offense while he is unavailable.
Boston Red Sox interim manager Chad Tracy had earlier provided positive injury news about three players—Roman Anthony, Trevor Story, and Isiah Kiner-Falefa—approaching Minor League rehab assignments.
The injury adds to Red Sox concerns as they pursue a playoff berth, with a 65-57 record and a recent skid of six losses in seven games.
A hamstring injury raises concerns about the severity, with potential implications for a lengthy stint on the injured list depending on tests and evaluations.
The Red Sox were scheduled to continue a road trip against the Pirates, then return home to face the Diamondbacks and Giants, followed by trips to Miami and Yankee Stadium to close August.
If placed on the injured list, the Red Sox could promote hitters from Triple-A; Trevor Story’s rehab timeline is expected to begin soon, potentially reopening a roster spot.
