MELBOURNE, Australia (AP) — He knew the extreme heat rule would come into play whether or not he broke Jannik Sinner's serve Saturday in the third game of the third set.
Eliot Spizzirri went ahead and broke the two-time defending champion 's serve anyway, taking confidence and momentum into an eight-minute break while the roof closed over the Australian Open's main stadium.

After the interruption, momentum swung completely. Sinner, staggering with cramps and completely distracted before the interval, regained his composure while the roof was closing and again in a 10-minute “cooling break” before the fourth set.
Sinner won it 4-6, 6-3, 6-4, 6-4 and advanced to the round of 16, later admitting he might have got lucky with the timing of the heat rule. The timing of the roof closure generated plenty of backlash on social media.
But Spizzirri took a very matter-of-fact approach to his defeat.
“Yeah, I don’t know if he got saved by it,” the 24-year-old American said. "I smiled a little bit when the heat rule went into effect, just because it was kind of funny timing as I went up 3-1. But at the same time, you know, the game at 2-1 in the third set was when the heat (scale) hit 5.0.
“So whenever that game was over, whether I broke or whether he held, we were going to close the roof. It was just funny that right when I broke and he was wobbling, that it happened to happen that way.”
“That’s the rules of the game,” he said. “And, you know, you got to live with it.”
Sinner made a recovery under similar circumstances against Holger Rune at a previous Australian Open, and Spizzirri said obviously the world's No. 2-ranked player had worked out ways to combat his cramps.
Spizzirri played college tennis in Texas, and said conditions he'd experienced in Austin and in other places like Florida were worse than Saturday's dry, hot day in Melbourne.
On the men's tour, he'd said he'd played in China last year where the court temperature reached 123 degrees Fahrenheit (51 Celsius).
“I don’t think it was even ballpark close to that today,” said Spizzirri, who made his main draw debut at Melbourne Park this year. “So, yeah, I felt pretty fresh, to be honest, and felt like I could have gone a lot longer.”
The temperature was around 35 degrees Celsius (95 Fahrenheit) when the tournament’s heat scale hit a maximum of 5. The maximum Saturday didn’t quite hit the forecast of 40 degrees Celsius (104 Fahrenheit).
While he said he was conditioned to play in extreme heat, Spizzirri accepted that the tournaments had to apply rules for player protection.
“I’ve played in way worse conditions. I’ve trained in way worse conditions. In college we played in brutal conditions at times in Austin,” he said. "Maybe that’s just a good thing to have under my belt.
“But at the same time, this rule is protection for us. I think it will hopefully promote guys to stay healthier for a longer period of time throughout the season, because playing these matches in this heat for an extended period of time over and over, day after day, is really tough on the body.”

NEW YORK (AP) — No quick dispatching of disease investigators. No televised news conference to inform the public. No timely health alerts to doctors.
In the midst of a hantavirus outbreak that involves Americans and is making headlines around the world, the U.S. government's top public health agency, the Centers for Disease Control and Prevention, has been uncharacteristically missing in action, according to a number of experts.
To President Donald Trump, "We seem to have things under very good control," as he told reporters Friday evening.
To experts, the situation aboard a cruise ship has not spiraled because, unlike COVID-19 or measles or the flu, hantavirus does not spread easily. It has been health experts in other countries, not the United States, who have been dealing primarily with the outbreak in the past week.
“The CDC is not even a player," said Lawrence Gostin, an international public health expert at Georgetown University. “I've never seen that before.”
Not until late Friday did CDC actions accelerate.
Health officials confirmed the deployment of a team to Spain's Canary Islands, where the ship was expected to arrive early Sunday local time, to meet the Americans onboard. They said a second team will go to Offutt Air Force Base in Nebraska as part of a plan to evacuate American passengers from the ship to a quarantine center. Also, the CDC issued its first health alert to U.S. doctors, advising them of the possibility of imported cases.
The CDC's diminished role in this outbreak is an indicator the agency is no longer the force in international health or the protector of domestic health that it once was, some experts said.
The hantavirus outbreak is “a sentinel event” that speaks to “how well the country is prepared for a disease threat. And right now, I’m very sorry to say that we are not prepared,” said Dr. Jeanne Marrazzo, chief executive officer of the Infectious Diseases Society of America.
Early last month, a 70-year-old Dutch man developed a feverish illness on a cruise ship traveling from Argentina to Antarctica and some islands in the South Atlantic. He died less than a week later. More people became sick, including the man's wife and a German woman, who both died.
Hantavirus was first identified as a cause of sickness of one of the cases on May 2. The World Health Organization swung into action and by Monday was calling it an outbreak. About two dozen Americans were on the ship, including about seven who disembarked last month and 17 who remained on board.
For decades, the CDC partnered with the WHO in such situations. The CDC acted as a mainstay of any international investigation, providing staff and expertise to help unravel any outbreak mystery, develop ways to control it and communicate to the public what they should know and how they should worry.
Such actions were a large reason why the CDC developed a reputation as the world's premier public health agency.
But this time, the WHO has been center stage. It made the risk assessment that has told people the outbreak is not a pandemic threat.
“I don’t think this is a giant threat to the United States,” said Jennifer Nuzzo, director of Brown University’s Pandemic Center. But how this situation has played out “just shows how empty and vapid the CDC is right now,” she said.
The current situation comes after 16 tumultuous months during which the Trump administration withdrew from the WHO, has restricted CDC scientists from talking to international counterparts at times and embarked on a plan to build its own international public health network through one-on-one agreements with individual countries.
The administration has laid off thousands of CDC scientists and public health professionals, including members of the agency's ship sanitation program.
As this was playing out, Trump's health secretary, Robert F. Kennedy Jr., said he was working to “restore the CDC’s focus on infectious disease, invest in innovation, and rebuild trust through integrity and transparency.”
The CDC has not been completely silent on hantavirus.
The agency on Wednesday issued a short statement that said the risk to the American public is “extremely low,” and described the U.S. government as “the world’s leader in global health security.”
Said Nuzzo: “Not only was that not helpful, it actually does damage because a core principle of public health communications is humility.”
The CDC's acting director, Dr. Jay Bhattacharya, posted a message on social media that the agency was lending its expertise in coordinating with other federal agencies and international authorities. Arizona officials this week said they learned from the CDC that one of the Americans who left the ship — a person with no symptoms and not considered contagious — had already returned to the state. WHO officials said the CDC has been sharing technical information.
The CDC also is “monitoring the health status and preparing medical support for all of the American passengers on the cruise,” Bhattacharya wrote.
But federal health officials have mostly been tight-lipped, declining interview requests.
In interviews this week, some experts made a comparison with a 2020 incident involving the Diamond Princess, a cruise ship docked in Japan that became the setting of one of the first large COVID-19 outbreaks outside of China.
The CDC sent personnel to the port, helped evacuate American passengers, ran quarantines, shared genetic data on the virus, coordinated with the WHO and Japan, held public briefings and rapidly published reports “that became the world’s reference data on cruise ship COVID transmission,” said Dr. Tom Frieden, a former CDC director.
Some aspects of the international response to the Diamond Princess were criticized, and it did not halt the outbreak or stop COVID-19’s spread across the world. But some experts say it was not for the CDC's lack of trying.
“The CDC was right on top of it, very visible, very active in trying to manage and contain it,” Gostin said, while the agency's work now is delayed and subdued.
Instead of working with nearly all of the world's nations through the WHO, the Trump administration has pursued bilateral health agreements with individual nations for information sharing, public health support, and what it describes as “the introduction of innovative American technologies.” Roughly 30 agreements are currently in place.
That's not sufficient, Gostin said. “You can't possibly cover a global health crisis by doing one-on-one deals with countries here and there,” he said.
