Philadelphia Phillies reliever Daniel Robert collapsed following a Sunday bullpen session in spring training. However, Robert, who has an implanted defibrillator that was activated during the incident, was "stable and alert" and was transported to a local hospital for evaluation.

Why it matters

Robert's cardiac event last year and subsequent defibrillator implantation raised concerns about his long-term health and ability to continue his MLB career. This latest incident highlights the ongoing challenges professional athletes can face with heart-related issues.

The details

Robert, 31, spent the 2025 season in the Phillies organization after they acquired him in April via a trade with the Texas Rangers. On Oct. 31, weeks after the Phillies were eliminated by the Dodgers in the NLDS, Robert collapsed unconscious on the mound while throwing. Medical staff gave him CPR and then used a defibrillator to shock his heart back into rhythm. After months of close evaluation, it was determined that Robert had not suffered a heart attack but had instead experienced an "unknown cardiac event." Afterward, Robert went on blood-pressure medication and had the defibrillator implanted.

  • On Oct. 31, Robert collapsed unconscious on the mound while throwing.
  • Prior to Sunday's incident, Robert had been cleared to play since February, but the Phillies had been taking a cautious approach with his spring.
