Aryna Sabalenka, the eventual 2024 US Open champion, took the court docket for her third-round match towards Ekaterina Alexandrova on Arthur Ashe Stadium at 12:08 a.m. It was the latest-ever begin for a match on the US Open.

Two days later, within the spherical of 16, Zheng Qinwen and Donna Vekic left the court docket on Ashe at 2:15 a.m. in what was the most recent end for a girls’s match on the event.

These late begins have a direct impact on the opportunity of being injured, in line with a latest report compiled by the Skilled Tennis Gamers Affiliation (PTPA) and shared with ESPN. It indicated a large enhance in damage danger for gamers taking part in night time matches in comparison with these performed earlier within the day.

In keeping with the PTPA report, which used knowledge from Grand Slam occasions happening from April 2018 via Could 2024, as the share of night time matches (beginning after 7 p.m.) elevated, the damage price additionally elevated from 4.6 to five.2%.

PTPA medical director Dr. Robby Sikka, who led the staff that performed the information evaluation, mentioned odds ratios had been calculated that indicated a participant is 25% extra more likely to be injured throughout a match performed at night time.

And but, night time matches at main tournaments stay on the rise — going from a bit of below 7% to greater than 11% within the examine. That quantity is anticipated to extend to greater than 15% as soon as knowledge from this yr’s US Open is included, Sikka informed ESPN.

Gamers have routinely expressed considerations about how taking part in later matches impacts their well being and efficiency.

Coco Gauff, the 2023 US Open champion and present world No. 6, referred to as post-midnight finishes “not wholesome” on the French Open in June. Novak Djokovic, the 24-time main champion and co-founder of the PTPA, mentioned he struggles with late-night matches at this stage of his profession.

“I do not suppose that growing older helps actually staying so late and taking part in very late,” Djokovic, 37, mentioned after his first-round match on the US Open, which was the second night time match on Ashe. “I can really feel, you realize, my batteries are low now. I am shutting down.”

Djokovic’s third-round match on the French Open this summer season — a five-set win over Lorenzo Musetti — ended at 3:06 a.m. and was the most recent end in event historical past. He tore the meniscus in his proper knee throughout his subsequent match and withdrew forward of the quarterfinals and underwent surgical procedure.

Daria Kasatkina, presently No. 13 on the planet, informed ESPN that the night time would not finish when the match is over.

“You can’t fall asleep right away … you have got some interviews straight after, you then should do stretch, ice tub restoration, eat, then obligatory media, [such as] a press convention or no matter you can be requested to do,” she mentioned.

Kasatkina identified that every athlete has his or her personal restoration/rehab routine. The athlete then has to make the journey again to the lodge which, relying on the event, can take an extra half-hour or extra.

Kasatkina has expertise with late matches. In August 2023, she performed Elena Rybakina in a Canadian Open match that began at 11:27 p.m. They completed practically 3½ hours later at 2:57 a.m.

“You are destroyed,” Kasatkina mentioned of late matches. “You spend a number of emotion, a number of bodily vitality.”

To compound the impact, scheduling doesn’t all the time take when a earlier match ends into consideration.

“You may play first the day after you play final,” Kasatkina mentioned.

PTPA govt director Ahmad Nassar famous the athletes’ frustration round more and more late begin instances and turned to Sikka to seize their considerations with goal knowledge.

“[Dr. Sikka] was a man that we knew via baseball and soccer and basketball and we mentioned, ‘Hey, would you be excited by type of taking a look at a few of these points and dealing with us on this?'”

The outcomes, whereas not notably shocking, offered quantifiable metrics to help what the athletes had been reporting from private expertise.

“It is one factor to grouse, ‘I do not like late-night matches,’ Nassar mentioned. “It is a lot totally different to say, this is some actual knowledge, 25% higher likelihood of damage. … After which, you realize, you type of go to what do you do about it?”

The ATP, which runs males’s tennis worldwide, declined to remark for this story. A consultant shared the group’s joint press launch with the WTA from January explaining modifications each excursions had made to alleviate late-night matches.

Within the launch, which acknowledged how such late begins and finishes had been “negatively impacting gamers and followers,” it said varied rules for tour occasions, together with the banning of matches beginning after 11 p.m. (until accepted by a tour supervisor), the transferring of matches to an alternate court docket if not began by 10:30 p.m. and the disallowing of night time periods to start after 7:30 p.m. ET.

These modifications went into impact at first of the 2024 season. Amy Binder, the WTA’s senior vice chairman of worldwide communications, famous that as of Sept. 10, there was only one occasion when a match at a WTA occasion began after 11 p.m. for the reason that change went into impact and it was “in full session and settlement with the competing athletes.”

The 4 Grand Slam occasions function independently from the excursions, nevertheless, and don’t have to abide by the identical rules. Wimbledon has had a curfew of 11 p.m. in place because it added the roof to Centre Courtroom in 2009 in an settlement with native officers. The US Open carried out its personal coverage associated to nighttime matches this yr. If the second night time match on Arthur Ashe Stadium or Louis Armstrong Stadium had not began by 11:15 p.m., the match may have been moved to a different court docket.

“The referee can have the discretion to maneuver the match,” event director Stacey Allaster mentioned in a pre-event media briefing in August. “That is going to rely on many variables, like do now we have the published staff prepared, do now we have a ball crew, so forth.”

However Sabalenka and Alexandrova took the court docket properly after 11:15 p.m. Nassar mentioned each gamers had been consulted and mentioned they wished to stay on Ashe. However Nassar would not imagine it ought to have come all the way down to the gamers making the decision.

“This won’t be the most well-liked opinion, however you do not ask a participant within the NFL, ‘Oh, how do you’re feeling? You need to stick it out even when we predict you have got a concussion?’ No, man, the rule is you gotta go,” Nassar mentioned. “That is a part of altering the tradition and I do know gamers need to play on sure courts at sure tournaments, that is pure. However [we’re at] the purpose the place the tradition is definitely harmful. Not simply annoying, however harmful.”

Participant considerations usually are not strictly restricted to late-night match begins. Points reminiscent of obligatory event calls for, the transition of a number of of the 1000-level occasions from one week to 2, and the variety of matches being performed are all areas of focus.

“The tournaments are longer, the attracts are greater. Restoration time is much less,” mentioned Kasatkina.

“Plus the journey is rising as a result of now we have extra tournaments. Now we have to journey from one coast to a different, from one time zone to a different. Now we do not have a lot time for preparations. We can not do a lot follow blocks. We will not get sufficient relaxation. I imply, you possibly can, however you need to sacrifice a number of the tournaments. Such as you all the time have to select.”

There are additionally the floor modifications that accompany totally different venues factoring into the equation for gamers.

Hubert Hurkacz, presently ranked No. 8, mentioned always altering surfaces is hard on gamers. He famous that was very true this yr with the addition of the Olympic Video games, performed on clay, following the top of the grass season and proper earlier than the beginning of the summer season hard-court portion of the schedule.

“For instance you are going to the Olympics, you are practising for per week on clay or preparing, your physique’s able to go,” Hurkacz informed ESPN. “Then you definately play a great event after which the subsequent day you are on the flight say to Montreal, and also you’re taking part in on a distinct floor, totally different situations on laborious court docket, [where] the sliding is a lot totally different. … Finally it is actually tough with out having correct preparation.”

Sikka notes the PTPA is trying to study from different sports activities leagues and their strategy to knowledge analytics as a way of effecting change.

“How did the NFL strategy their concussion knowledge?” he mentioned. “If baseball has all these arm and elbow accidents and so they’re anxious about pitch counts, ought to now we have a serve depend?”

He famous the ability period of tennis, when increased spin charges and serve velocities seem to correlate with possibilities of successful. However is there an damage price? The reply, Sikka believes, lies within the knowledge.

“No knowledge is ideal,” he mentioned. “However these are traits which can be fairly indeniable. And now there is a measurable factor that if we need to intervene, we have got a baseline for comparability.”

Sikka additionally believes the options lie within the PTPA, the excursions and the Slams working collectively in the direction of a standard aim of optimizing participant well being and efficiency.

“We’re not right here to place individuals down,” Sikka mentioned, “We’re not right here to rabble rouse. We’re right here to enhance the standard of look after a inhabitants.”
