Episode notes
Hip Drill That Triggered A Cascade
- Declan Cronin described how a spring-training hip drill strained deep left-hip rotators and started a long rehab saga.
- He tried throwing through it, made rehab outings, then felt pain return and never fully regained pre-injury mechanics.
Compensation Patterns Can Break Pitching
- Declan and Miami staff observed compensatory movement patterns after low-intensity throwing changed his mechanics.
- Those compensations reduced pitch shape and created upper-body strain that later contributed to elbow failure.
The One Pitch That Ended It
- Declan recalled a single pitch where he felt his elbow "space expand" and a painful pop at release.
- He immediately recognized it as a UCL tear and later confirmed the ligament was shredded.
