The Houston Astros bullpen has taken an early hit this spring with left-handed reliever Bennett Sousa sidelined by an oblique injury.
Sousa reportedly felt discomfort during a throwing session, a common mechanism for this type of injury in pitchers who rely heavily on rotational power.
What Is an Oblique Strain?
The oblique muscles run along the sides of the abdomen and play a critical role in rotational movement, core stability, and force transfer during throwing.
In baseball, they are heavily stressed during the pitching motion, especially during the acceleration phase.
An oblique strain occurs when these muscle fibers are overstretched or torn. Symptoms typically include:
- Sharp pain in the side of the abdomen
- Pain with rotation, coughing, or throwing
- Decreased velocity or control in pitchers
Treatment and Rehab
Treatment depends on severity but generally includes:
- Rest from throwing and rotational activities
- Anti-inflammatory strategies
- Progressive core strengthening
- Gradual return to throwing mechanics
Unlike some injuries, oblique strains require full healing before return, as premature activity significantly increases reinjury risk.
Return-to-Play Timeline
Typical recovery timelines:
- Mild strain: 2–3 weeks
- Moderate strain: 4–6 weeks
- Severe strain: 6–8+ weeks
For Sousa, a realistic expectation is a 4–6 week return window, depending on symptom resolution.
Takeaway for Houston Athletes
Oblique strains are common in baseball, golf, and pickleball. If you feel sharp side pain with movement, don’t push through it. Early evaluation and guided rehab are key to avoiding prolonged downtime.
