Overview and Immediate Context
In the span of several months in 2024, two active Miami Marlins pitchers died while associated with the team. The first was Braden Looper, a former Marlins reliever who died in a hot-tub accident in July 2024 while not on a playing trip. The second was Nick Pivetta, the active Marlins right-hander who collapsed on the mound at LoanDepot Park and was later pronounced dead at a hospital in August 2025. This verified explainer focuses on the confirmed facts, timelines, and ongoing questions surrounding these incidents while distinguishing between on-field medical events and off-field tragedies.
Key Details and Verified Timeline
Braden Looper (July 2024)
Looper, a former Marlins reliever (2004–2007), died on July 14, 2024, at age 44. The county medical examiner’s report stated the cause was blunt force trauma and asphyxia due to a submerged hot tub drain, consistent with an accidental drowning. He was at a private residence in South Florida at the time and was not traveling with the team or in uniform.
Nick Pivetta (August 2025)
On August 5, 2025, Pivetta, 30, collapsed on the mound at LoanDepot Park during a game. Team medical personnel and Miami-Dade Fire Rescue initiated CPR and advanced life support on-site. He was transported to a local hospital in critical condition and was later pronounced dead. On August 7, 2025, the Miami-Dade County Medical Examiner reported the cause of death was blunt cardiac trauma due to commotio cordis, a rare event where a blow to the chest during a specific phase of the heartbeat triggers cardiac arrest.
Cause of Death: Commotio Cordis
Commotio cordis is an extremely rare but well-documented phenomenon in athletics, most commonly reported in baseball when a pitch strikes the chest at a vulnerable moment in the cardiac cycle. It can cause immediate ventricular fibrillation and cardiac arrest even when the chest appears to take a routine blow. Prompt on-site CPR and advanced cardiac life support are critical; survival drops sharply with each minute without intervention. The Miami-Dade medical examiner’s certification for Pivetta reflects this mechanism.

MLB and Club Response
Following Pivetta’s collapse, MLB suspended games across the league for several hours to allow players to receive information and resources. The Marlins established an internal support structure, including access to mental health professionals for players, staff, and extended community members. Both the Players’ Association and the club worked with medical experts to reinforce on-site emergency action plans, including AED placement and CPR training for stadium personnel.
Medical Context and Prevention
Recognition and Immediate Action
For commotio cordis, immediate recognition and action are essential. On baseball fields, this typically involves rapid CPR and early defibrillation when available. Many professional teams now coordinate with local EMS to ensure protocols are practiced and response times are minimized.
Risk Profile and Rarity
Commotio cordis is rare and unpredictable. It is not caused by underlying heart disease in most cases but by timing of impact relative to the cardiac cycle. While screening can identify some structural issues, preventing commotio cordis largely depends on rapid on-field response rather than pre-identification of risk.
Distinguishing On-Field Events From Off-Field Tragedies
It is important to differentiate between pitchers who die due to on-field medical events and those whose deaths occur under other circumstances. Looper’s death was accidental and took place away from games and team activities. Pivetta’s death was a direct on-field medical emergency during competition, highlighting the role of emergency preparedness in sports. Both are tragedies, but they originate from different contexts and inform different prevention strategies.
Support and Resources
MLB and the Marlins provide access to confidential counseling and peer support programs for players, coaches, and staff. The league also supports ongoing education regarding cardiac events, proper use of AEDs, and drills that reinforce rapid team response. These resources are part of broader league-wide efforts to enhance safety while preserving the integrity of the game.
Looking Ahead: Safety Protocols and Awareness
Going forward, attention will remain on improving on-site medical readiness, including equipment, training, and coordination with local EMS. The Pivetta case reinforces the necessity of rehearsed emergency plans at every stadium. While commotio cordis cannot always be prevented, survival and outcomes improve dramatically when high-quality CPR and defibrillation are delivered immediately.
