Holger Rune urges ATP to add heat rule after Shanghai Masters chaos
When Holger Rune, Danish player asked officials if players had to "die on court" during the opening rounds of the Shanghai MastersShanghai, the tournament’s brutal heat turned into a flashpoint for player‑health debate. Temperatures hovered around 31 °C (88 °F) and humidity spiked past 80 % for several days, prompting a spate of mid‑match retirements that reshaped the draw and sent shockwaves through the tennis world.
Background: How heat rules work in tennis
Grand Slam events already have a built‑in safety net: once the temperature‑humidity index (THI) hits a preset ceiling, play can be suspended or delayed. The ATP has historically left heat‑related decisions to tournament directors, citing player fitness and scheduling constraints. That hands‑off approach has been tested before – the 2022 Indian Wells event saw a brief pause when temperatures topped 38 °C, but nothing as sustained as the Shanghai heat wave.
Rune’s call mirrors a growing chorus of voices asking: why should players at a Master 1000 event be left out in the scorching sun while Grand Slam champs get a cooling break? The debate isn’t new, but the Shanghai drama gave it a fresh urgency.
What happened in Shanghai?
The opening day of the Shanghai Masters featured a dry, relentless sun that turned the outdoor hard courts into an oven. By the third round, the cumulative strain was evident. World No. 2 Jannik Sinner clutched at his right thigh, cramping so badly he had to concede the match to Tallon Griekspoor. "My leg just stopped working," the Italian said, his voice hoarse.
Novak Djokovic, the sport’s marquee name, was visibly ill, retching during his clash with Yannick Hanfmann before rallying to a hard‑won victory. "It’s brutal," Djokovic later admitted, "especially with 80 % humidity day after day. You feel every drop of sweat as a weight."
In total, seven high‑profile players retired before the quarter‑finals:
- Casper Ruud
- Tomas Machac
- David Goffin
- Terrence Atmane
- Hamad Medjedovic
- Wu Yibing
The withdrawals threw the draw into disarray, paving the way for lower‑ranked players to advance further than expected. For fans, the excitement was muted; for organizers, the spectacle turned into a logistical nightmare.
Players speak out
During a medical timeout in his match against Ugo Humbert, Rune was heard saying, "Do we have to die on court?" He later pressed the issue at the post‑match press conference, insisting, "We’re fit, we’re strong, we’re mentally tough, but there is a limit. A rule like the one at the Grand Slams would let us pause when it gets too dangerous."
Other affected athletes echoed similar concerns. "I’m a professional, but you can’t train to run on a furnace," Ruud said, dripping with perspiration after his retirement. "We need a safety blanket that says, ‘When it gets this hot, we stop.’"
Even Djokovic, who famously thrives in tough conditions, acknowledged the need for a formal safeguard: "I love a challenge, but the body is not a machine. When the humidity stays that high, it’s not just uncomfortable—it’s risky for heart and kidney function."
ATP’s response and possible policy shift
Following the backlash, a senior spokesperson for the ATP told reporters, "We are reviewing the situation in Shanghai and will consult with players, medical experts, and tournament officials about a potential heat‑index rule." The governing body has not yet proposed a concrete threshold, but sources say a THI of 82 or higher could trigger a temporary suspension, similar to the Grand Slam model.
Analysts note that any rule change would ripple across the tour’s 62 week calendar. A heat rule could force rescheduling of matches, affect broadcast windows, and potentially increase costs for venues that would need cooling infrastructure.
Nevertheless, the consensus among the players’ union is clear: protect health, preserve the sport’s integrity. "If we keep pushing athletes to the brink, we risk long‑term damage and lose fans who don’t want to watch people collapse on court," said a representative of the ATP Players’ Council.
Implications for future tournaments
Should the ATP adopt a heat rule, we could see several immediate effects. First, tournament directors in hot climates—like the upcoming events in Miami, Indian Wells, and the Asian swing—might install more shade structures or invest in air‑conditioning for player lounges. Second, scheduling could become more flexible, with earlier start times to avoid peak heat.
Fans may also benefit. A pause for extreme weather would keep matches competitive and reduce the odds of abrupt retirements that leave spectators disgruntled. Sponsorship deals could become more stable, as broadcasters won’t have to scramble for filler content when matches are halted.
On the flip side, critics argue that heat rules could disrupt the sport’s tradition of testing endurance. "Part of tennis is dealing with the elements," said a veteran commentator, "but there’s a line between a test and an avoidable health hazard." The upcoming decision will likely set a precedent that other sports—like cricket and rugby—could look to when drafting their own climate‑related policies.
What’s next?
The Shanghai Masters finishes on Oct 11, 2025, but the conversation will continue well beyond the final match. A meeting of the ATP’s International Player Council is slated for early November, where a formal proposal could be tabled. In the meantime, players are expected to voice their concerns at the next tournament in Mumbai, where another heat‑prone venue looms.
Frequently Asked Questions
How would a heat rule affect players like Jannik Sinner?
A heat rule would let Sinner request a pause when the temperature‑humidity index crosses a set limit, giving his body a chance to recover. It could prevent cramping episodes like the one that forced his retirement, preserving his tournament run and ranking points.
What triggered the ATP to consider a formal heat policy now?
The unprecedented number of retirements at the Shanghai Masters, combined with vocal demands from stars like Holger Rune, forced the ATP to reassess player‑safety standards under extreme weather conditions.
Will tournaments in cooler climates be exempt from the rule?
The rule would be triggered by the actual temperature‑humidity reading, not by geography. So a sudden heat wave in a normally cool city could still activate a suspension, ensuring uniform safety standards worldwide.
How might sponsors react to potential match delays?
Sponsors generally prefer uninterrupted play, but most major contracts include clauses for weather‑related interruptions. A clear, consistent heat policy could actually reassure sponsors that any delays are managed transparently and fairly.
What are the next steps for the ATP and players?
The ATP will convene its International Player Council in November to draft a formal proposal. If agreed, the new heat rule could be trialled at the next Asian swing, giving both organizers and athletes a chance to adjust before a full rollout.

October 8, 2025 AT 02:47Man, the Shanghai heat was like stepping into a sauna while trying to sprint a mile.
I could almost hear Holger Rune whisper “do we have to die on court?” and the whole crowd feeling the sweat dripping off the players.
The humidity was relentless, turning every rally into a slow‑motion battle.
It’s wild how the tournament kept rolling with no pause, even as muscles cramped and lungs burned.
Honestly, a heat rule would just be common sense, no drama needed.

October 11, 2025 AT 14:07From a coaching perspective, you want athletes to push limits but not at the expense of health. The body’s cooling mechanisms get overwhelmed when the THI spikes, leading to cramping and even collapse. A standardized heat suspension, like the Grand Slams, gives a clear safety net while keeping the competition fair. Plus, it lets trainers plan re‑hydration breaks without guessing. Bottom line: protect the players and the show stays exciting.

October 15, 2025 AT 01:27While the emotive lamentations echo across the forums, the empirical data suggests a statistically insignificant correlation between ambient temperature and match outcomes beyond a THI threshold of 82. The prevailing narrative neglects the thermodynamic elasticity inherent in elite physiological conditioning, thereby indulging in sensationalist hyperbole. A nuanced policy calibrated to specific enthalpic indices would obviate the need for ad‑hoc interventions. Nonetheless, the current laissez‑faire paradigm remains suboptimal.

October 18, 2025 AT 12:47Hey guys, just a quick heads up – the ATP actually has some guidelines for extreme heat but they’re not mandatory at most Masters events. If you look at the ITF's THI chart, 31°C with 80% humidity pushes the index over 80, which is the sweet spot for a pause. Players can request a medical timeout and the umpire can call a break if it’s legit. Also, staying in the shade between points and using ice vests can cut core temp by a few degrees. Hope that helps!

October 22, 2025 AT 00:07It is incumbent upon the governing bodies to institute a uniform heat‑index protocol, thereby ensuring athlete welfare whilst preserving the integrity of competition. Failure to adopt such measures may precipitate undue physiological stress and compromise the sport's reputation.

October 25, 2025 AT 11:27The proposition of instituting a heat‑index suspension is not merely an affectation of contemporary climate anxieties, but rather a requisite evolution of the sport’s regulatory architecture. In the annals of tennis, the dichotomy between tradition and innovation has repeatedly manifested in the form of equipment modifications, surface alterations, and now, arguably, environmental safeguards. Empirical studies conducted by the International Institute of Sports Medicine have demonstrated a correlation coefficient of 0.73 between elevated THI values and the incidence of acute musculoskeletal failure among professional athletes. Moreover, the thermoregulatory strain imposed by a sustained ambient temperature of 31 °C coupled with relative humidity exceeding 80 % compromises homeostatic mechanisms, precipitating hyperthermia and electrolyte imbalance. One must also consider the macro‑economic ramifications: tournament broadcasters suffer from viewership attrition when marquee matches are truncated by physiological withdrawals, thereby eroding advertising revenue streams. The athletes themselves are not mere commodities; they are biological systems with finite adaptive capacity, and the imposition of a calibrated THI threshold could function as a safeguard against long‑term morbidity. While purists may decry the encroachment of regulatory intervention as antithetical to the sport’s ethos of endurance, the empirical evidence compels a reassessment of what constitutes ‘acceptable’ hardship. The precedent set by Grand Slam events, wherein a THI of 82 triggers a mandated suspension, delineates a pragmatic benchmark that could be extrapolated to the Masters 1000 tier. In addition, the logistical feasibility of such implementation has been corroborated by venue case studies demonstrating the deployment of mobile cooling units and shaded corridors with negligible impact on scheduling. Critics who posit that heat is an intrinsic variable akin to wind or sun exposure neglect the asymmetrical physiological burden it imposes when compounded by high humidity. Consequently, the formulation of a uniform, data‑driven heat policy should be prioritized on the ATP calendar, with stakeholder consultations encompassing medical experts, player unions, and tournament directors. Ultimately, safeguarding player health aligns with the broader strategic objective of sustaining the sport’s global appeal and commercial viability. Furthermore, a standardized protocol would facilitate data collection across venues, enabling longitudinal analyses of heat-related attrition rates. Such granular analytics could inform future adjustments to threshold values, ensuring they remain commensurate with evolving climatic patterns. It would also provide a transparent framework for players to plan their conditioning programs, reducing uncertainty and fostering competitive equity. In sum, the convergence of physiological science, economic imperatives, and ethical responsibility culminates in a compelling case for immediate policy action.
