Jannik Sinner faces a new test after two months away from competition

Yesterday 12:00

For much of the past few seasons, Jannik Sinner’s presence at the top of men’s tennis has become almost routine. The Italian has built his status around consistency, major titles and an ability to sustain an exceptional level across the season.

His latest challenge, however, is different. After winning Wimbledon on July 12 against Alexander Zverev, Sinner was forced away from competition by a right-knee injury, ending his participation in the North American hard-court swing and eventually ruling him out of the US Open.

The absence has created a rare interruption in the rhythm of the world No. 1. It has also allowed the players behind him to reshape the competitive landscape.

Zverev turns Wimbledon defeat into a major breakthrough

Zverev left Wimbledon without the trophy after losing to Sinner in four sets, but the German's season has since taken another turn.

His breakthrough had already arrived at Roland Garros, where he captured his first Grand Slam title in June. At the US Open in September, he added a second major by defeating American Ben Shelton 6-3, 7-6(2), 5-7, 6-2 in the final.

That New York triumph transformed Zverev's position in the race at the top of the sport. In the space of three months, he moved from a player still seeking his first Grand Slam to a two-time major champion in the same season.

The contrast with Sinner is striking: while the Italian was recovering away from the tour, his principal rival was accumulating the biggest titles available.

The knee is only one part of Sinner's comeback

Sinner's physical condition remains the immediate issue. When he announced his US Open withdrawal on August 21, he said that further recovery time was necessary because of the right-knee problem.

The decision ended a remarkable run in 2026. Before the injury interrupted his campaign, Sinner had compiled a 44-3 record and won six titles, including Indian Wells, Miami, Monte Carlo, Madrid, Rome and Wimbledon.

But returning to competition involves more than determining whether an injury has healed.

After weeks without an official match, Sinner will have to rebuild competitive timing, manage the physical demands of long matches and recover the intensity that made him so difficult to beat during the first part of the season.

The ranking cushion remains an important factor

Despite missing the US Open, Sinner has retained the No. 1 position. His lead over Zverev has nevertheless become a central storyline as the German continues to collect points and titles.

The situation also illustrates the importance of the ATP calendar. Sinner's ranking position is not determined solely by his current form but also by the points he accumulated during the corresponding period of the previous season.

That makes the closing months particularly significant. Every tournament Sinner enters will carry two questions: how quickly can he return to his previous level, and how much of his ranking advantage can he preserve while doing so?

A different competitive landscape awaits

When Sinner returns, he will not be coming back to exactly the same tour he left in July.

Zverev has now won Roland Garros and the US Open, while Sinner's absence has given other contenders additional opportunities to close the gap. The German's rise also adds another dimension to a rivalry that produced one of the season's most important matches at Wimbledon.

Sinner won that final 4-6, 7-6(2), 6-3, 6-4 after recovering from an opening-set loss, successfully defending his Wimbledon crown and claiming his fifth Grand Slam title.

His return therefore carries an unusual element of uncertainty. The Italian does not need to rediscover his status as a leading player; instead, the immediate question is how quickly the level that produced six titles before Wimbledon can reappear after a prolonged interruption.

The next phase of the season

Sinner's comeback will be closely followed as the Asian swing and final stretch of the ATP season approach. His team had indicated after the US Open withdrawal that the recovery programme would focus on preparing him for tournaments in Beijing and Shanghai.

For Sinner, the objective is therefore not simply to step back onto a tennis court. It is to reconnect with the competitive routine that has defined his rise to the summit.

After two months away, the first matches will provide a clearer indication of how much the injury and interruption have changed his trajectory — and how quickly he can re-establish himself at the highest level.
