Zverev Loses His First Match as World No. 1, Then Hits Back at Becker and the Doubters

Two days. That is how long Alexander Zverev’s reign as world No. 1 lasted before it took its first defeat. The German, confirmed at the top of the rankings on Monday, lost his opening match at the Paris Masters on Wednesday, beaten 7-6 (5), 6-2 by Lorenzo Musetti in the second round. Then, instead of retreating into the usual platitudes, Zverev used his press conference to take on everyone who had spent those two days questioning whether he belonged there at all.

How did the match get away from him?

It turned in the first-set tiebreak, and it turned fast. Zverev led 5-2 and looked in control of a set in which, as Musetti himself put it, the German had served very well. Musetti then won six of the final seven points to steal it, and the second set was barely a contest after that: breaks for 2-1 and 5-2, sealed with an ace, in a match Reuters credits Musetti with 29 winners and eight aces. The head-to-head now stands at 4-2 to the Italian, which is worth remembering the next time someone calls this an upset out of nowhere. Musetti is a former world No. 5, a French Open and Wimbledon semi-finalist, and he has spent 2026 fighting injuries, including retiring while leading Novak Djokovic by two sets in the Australian Open quarter-final, before ending a four-year wait for a title in Lyon last month. This was a resurgence meeting a coronation, and the resurgence won.

What did Zverev say about the defeat?

He did not hide behind it. Zverev said Musetti played very well and he played very badly, calling it one of his worst matches in the last couple of months and adding, in short, that there were no excuses. That bluntness matters, because it separates the defeat from the argument that followed. Zverev was not claiming he deserved to win a match he lost. He was claiming he deserved the ranking he lost with, and those are different things.

Why was he so fed up?

Because the two days between confirmation and first match had been spent, in his view, litigating his right to the position. He said he felt like the only No. 1 in tennis history who had to explain why it was acceptable for him to be No. 1, and that he found that difficult, because he believes he deserves to be where he is. The doubts had a public airing on the tournament’s first day, when French journalist Frederic Verdier said on Eurosport that Zverev had beaten only three top-10 players this season and was benefiting from the absences of Jannik Sinner and Carlos Alcaraz. Jimmy Connors added on his podcast that Zverev now had an obligation to play like a two-time Grand Slam champion every time. The numbers behind the doubt are real enough: Tennis365 notes his 3-9 record against top-10 players in 2026 is the worst a No. 1 has achieved in the Open Era. The numbers behind the defence are real too: two Grand Slam titles, at Roland-Garros and the US Open, a tour-leading 65 match wins this year, and a year-end No. 1 position sealed when Bergs beat Alcaraz in Shanghai, with Sinner out for the rest of the season. Paris director Cedric Pioline said before the tournament that there is no such thing as a No. 1 by default, and Pete Sampras said in an ATP video message that the ranking was well deserved.

What did he say to Boris Becker?

Becker, the only other German man to reach No. 1, had told Der Spiegel this week that fans had mostly supported Zverev’s opponents in all three of his Grand Slam finals this year, and had questioned his silence on the war in Ukraine. Zverev answered in German, saying he did not know what was going on with Becker at the moment but felt he was looking for anything to put him down a bit. On the crowds, Zverev gave his own count: about 70 percent for him in Paris, about 50-50 at Wimbledon against Sinner, and a stadium against him in New York when he played an American, which he called normal. On Ukraine, he said nobody had ever asked him about it, that he was not going to post long political comments on Instagram, and that he never had and never would. The sting in the exchange is that Becker had hailed Zverev on his podcast with Andrea Petkovic only three weeks earlier as rightly and very deservedly the new world No. 1, saying nobody becomes No. 1 by chance. Something changed in three weeks, or Becker is doing two things at once, and Zverev clearly believes it is the former.

How rare is this kind of debut defeat?

Rarer than it feels, and that is why it travelled. Zverev is the fifth player to be confirmed as world No. 1 and then lose his very next match, Tennis365 reports, and the first since Carlos Alcaraz in September 2022. The Open Era precedents include John McEnroe in 1980 and Thomas Muster in 1996, and the Alcaraz case is the comforting one for Zverev: the Spaniard went on to reclaim the top spot and win seven majors. A debut defeat is not a verdict on a reign. It is, however, a terrible way to start answering the people who doubted it, and Zverev knows that better than anyone.

What happens next?

For the rankings, nothing immediate: Reuters notes Zverev has already secured his place at the season-ending ATP Finals in Turin, so Paris was about form and statement rather than qualification. That distinction also sharpens the contrast with Novak Djokovic’s Paris campaign, where a semi-final is still needed to keep the Turin chase alive. For Zverev, the next statement will have to come in Turin, against the best eight players in the world, without the shelter of a first-round bye or a friendly crowd. He arrived in Paris carrying the Dunlop ball complaint from his Vienna semi-final loss to Alex de Minaur, and he leaves it with a first-round exit and a public row with Becker. The doubters have their exhibit now. What they do not have is a final answer, and Zverev’s press conference made clear he intends to be the one who gives it.
