Alexander Zverev Won 65 Matches to Reach No. 1, Then Ruled Out the United Cup

On Friday in Vienna, Alexander Zverev ruled out the United Cup. He had beaten Arthur Fery 6-0, 6-2 in 58 minutes that afternoon to reach the Erste Bank Open semi-finals, a day after the win over Tallon Griekspoor that secured the world No. 1 ranking he will hold from Monday. In the press conference that followed, he said: “I’m not playing the United Cup 2027 (1-10 January), because it’s simply impossible for me.” He added: “At some point it’s nonsense. But I’ve been saying that for ten years and nothing changes.” He confirmed in the same press conference that he will play the Davis Cup.

“I would be an idiot to sit here and say that I was equally as good as Jannik. I wasn’t,” Zverev said after the Griekspoor match on Thursday night, making the case against himself. Jannik Sinner leads their head-to-head 11-4 and has won the last nine meetings, all five of them in 2026, including the Wimbledon final, 6-7(7), 7-6(2), 6-3, 6-4. Zverev has beaten neither Sinner nor Alcaraz this year. Carlos Alcaraz leads Zverev 7-6 after winning their Australian Open semi-final in five sets.

The method he described is built in December. Zverev said his off-season runs for four weeks, with five or six hours of fitness training every day and about an hour to an hour and a quarter of tennis, so that he can play a fifth set the way he plays a first. Fitness and health, he said, are an absolutely massive part of the sport. The cost of losing them is in his own record: in the 2022 French Open semi-final against Rafael Nadal, he rolled his right ankle, left the court in a wheelchair and needed surgery on all three lateral ligaments. He missed the rest of that season.

The Davis Cup Final 8 runs to 29 November in Bologna, and the United Cup opens in Perth and Sydney on 1 January. Germany face Great Britain in Bologna on 26 November, and Zverev was named in captain Michael Kohlmann’s squad on 26 October. Between the Davis Cup final and the United Cup’s first day there are 33 days. A four-week block starting on 30 November would run to 27 December, leaving four days before the United Cup opens, before the flight to Australia. Zverev’s version of the same arithmetic was that playing the Davis Cup means playing almost into December, and playing the United Cup would mean a first match at the end of December, with a holiday flown straight into Australia.

The ATP’s 2026 calendar did move. It cut the mandatory ATP 500 events for top-30 players from five to four and the ranking-counted events from 19 to 18, and it moved Los Cabos a week later to open a break after Wimbledon. Alcaraz, who missed four and a half months with a wrist injury sustained at Barcelona in April and did not return until the US Open, told Sky Sports on 8 October that the schedule was going in the wrong direction and that the ATP was pushing the players too much. The tour’s longer answer is the OneVision blueprint chairman Andrea Gaudenzi published in October: a bonus pool rising from $21.5 million to $50 million, $25 million of support for the top 250, $30 million a year for pensions, dedicated weeks for each tier of event and a tenth Masters 1000 in Saudi Arabia. All of it is scheduled from 2028 and subject to consultation, with a decision due at the year-end meetings in Turin. None of those measures shortens the season. Zverev’s own fix, stated on Friday, is to play two or three weeks less in the season, so that players have time first to rest and second to build their bodies up.

Cédric Pioline, director of the Rolex Paris Masters, answered the question in Paris on Friday. Asked whether Zverev was a worthy No. 1 or a No. 1 by default, he said: “There’s no such thing as being world No. 1 by default.” He cited the 2022 wheelchair exit at Roland-Garros, Zverev playing as a diabetic, and two Grand Slam titles this year. Paris will mark the rise with an ATP ceremony, and Zverev, the 2024 champion and top seed, has a bye into a meeting with the Lorenzo Musetti or Hubert Hurkacz winner. Griekspoor, who had beaten Zverev in three sets in Montreal in August, had said before Vienna of the overtake: “Absolutely not. Not a single hair on my head believes that.” Before Vienna, Griekspoor had called the US Open final pretty mediocre and said Zverev was always the one ready to step in when the other two dropped out. He also said he would not be surprised if Zverev ended with four or five Grand Slam titles.

Matthew Turner commented on TNT Sports’ Facebook post announcing the ranking. He put Zverev’s theory back to him in the fans’ words: “Staying fit and healthy is as much a part of sport as getting the results. There is no if in sport.” Turner also noted that Sinner and Alcaraz were absent only part of the year, not across all of the previous 52 weeks. Syed Aamir Ali Shah answered the same post with the charge in its shortest form: “He is world no 1 because there is no sincaraz.” Turner’s line is the December argument restated by a spectator. Shah’s is the objection Griekspoor voiced before Vienna.

Caron Dee held both positions at once: “He got lucky due to both Alcaraz & Sinner injuries this year but to be fare he too overcame hectic injury & prevailed due to persistence & hard work!” Vishal Mudgil framed the wait rather than the ranking: “After ‘So near yet so far’ and ‘being there but not quite’ Sascha Zverev has finally reached no.1 spot. 2026 was a dream year for him.” Dee’s comment answers Shah’s with the two halves of Zverev’s own case: the absences were real, and so was the work that kept him available.

In the other Vienna semi-final, Carlos Alcaraz beat Daniil Medvedev 6-4, 7-6 (7-2). Medvedev had beaten Adrian Mannarino 6-2, 6-3 on Friday to seal his place at the ATP Finals in Turin.
