Joel Peguero Begins Rehab Assignment to Recover from Hamstring Strain
The San Francisco Giants are one step closer to regaining a key piece of their bullpen. Right-handed relief pitcher Joel Peguero is scheduled to commence a rehab assignment with Triple-A Sacramento on Tuesday, April 7, as he works toward a return to the major league roster.
Understanding the Injury: Grade 2 Hamstring Strain
Peguero’s absence from the active roster stems from a Grade 2 left hamstring strain. This injury was initially suffered in early March and subsequently aggravated, leading the Giants to place him on the 15-day injured list on March 25.
In medical terms, a Grade 2 strain involves a partial tear of the muscle fibers, which typically requires a structured recovery period to ensure the tissue heals sufficiently to withstand the explosive movements required in professional pitching. Peguero has followed a progressive recovery path, which included a successful live bullpen session completed on March 30.
The Road to Recovery and Return Timeline
The transition to game action with Triple-A Sacramento represents the final phase of Peguero’s recovery. Whereas he is eligible to return from the injured list in mid-April, he will likely require several rehab outings to ensure he is fully cleared for his 2026 regular-season debut. This cautious approach allows the coaching and medical staffs to monitor his hamstring stability during live game scenarios.
Key Recovery Milestones
- Early March: Initial hamstring strain and subsequent aggravation.
- March 25: Officially placed on the 15-day injured list.
- March 30: Successful completion of a live bullpen session.
- April 7: Commencement of rehab assignment with Triple-A Sacramento.
Impact on the San Francisco Giants Bullpen
Peguero’s return is expected to stabilize the Giants’ late-inning options. Until his activation, the team has relied on existing depth to cover his middle-relief innings. His presence in the bullpen provides a proven arm that has maintained a .197 opponent batting average and recorded three career wins.
Peguero first made his major-league debut on August 21, 2025. During his 17 appearances for the Giants last season, he established himself as a reliable asset with the following statistics across 22.1 innings:
- ERA: 2.42
- WHIP: 1.03
- Holds: 4
- Strikeout-to-Walk Ratio: 17:8
