Stefanos Tsitsipas and Daniil Medvedev Lead US Open 2026 Comeback

The US Open 2026 men’s tournament has delivered an unexpected storyline as two familiar names, Stefanos Tsitsipas and Daniil Medvedev, have rediscovered their best Tennis and reached the fourth round. Their progress comes at a time when the draw has already lost several highly seeded players, creating an unusually open path toward the latter stages.

Tsitsipas entered New York ranked 53rd in the world after falling as low as 88 earlier in the year, while Medvedev arrived as the world No.8 but carrying serious doubts about his recent form. Neither player appeared to be an obvious contender before the tournament began.

That perception has changed quickly. Tsitsipas defeated 10th seed Arthur Fils in the opening round before producing another impressive comeback against 18th seed Jiri Lehecka. Medvedev, meanwhile, has moved through his opening three matches without dropping a set, defeating French big-server Arthur Rinderknech 6-4, 6-4, 6-4 in the third round.

Their resurgence is particularly notable because both players have spent recent seasons dealing with injuries, coaching changes, inconsistent results and early Grand Slam exits. Their performances in New York therefore represent more than progress in one tournament. They are evidence that experienced players can rebuild confidence even after periods when their careers appear to be moving backwards.

Why the US Open draw has created an opportunity

The men’s draw has been unusually unpredictable. Four players from the top 10 seeds were eliminated during the opening two rounds, immediately reducing the number of established contenders and opening opportunities for players outside the expected title conversation.

For Tsitsipas, this environment has been particularly valuable. As an unseeded player ranked 53rd, he entered the tournament without the same expectations that followed him during his peak years.

Instead of carrying the pressure associated with being a top contender, he has been able to approach matches more like an underdog. That psychological shift can be important for a player who has struggled with consistency.

Medvedev has experienced something similar despite being seeded seventh. His ranking suggested he belonged among the tournament favourites, but his recent results told a different story. Arriving in New York after losing three of his previous four matches meant confidence was hardly guaranteed.

The first three rounds have changed that narrative.

Tsitsipas produces his strongest Grand Slam run in years

Tsitsipas entered the US Open with a difficult recent Grand Slam record. He had won only five Grand Slam matches during the previous two years, making his progress into the fourth round particularly significant.

His opening-round victory over Arthur Fils immediately suggested that something had changed. Fils was seeded 10th, while Tsitsipas was unseeded, making the result an early indication that the Greek player could still compete with high-ranked opponents.

His third-round performance against Jiri Lehecka provided an even stronger statement. Tsitsipas lost the opening set 6-2 but responded emphatically, winning the next three sets 6-1, 7-6(3), 6-1.

The comeback demonstrated both physical resilience and tactical adaptability. Rather than allowing the slow beginning to dictate the match, Tsitsipas changed the momentum and took control.

He has now reached the fourth round in New York for the first time in his career and is competing in the second week of a Grand Slam for the first time since 2024.

Tsitsipas’ recent struggles make the turnaround more significant

The 28-year-old has experienced an unusually turbulent period. A chronic back problem affected his previous season and made it difficult for him to establish continuity.

Tsitsipas explained that the recurring problem created constant worry and eventually affected his enjoyment of training. That detail helps explain why his current resurgence means more than simply winning several matches.

Professional tennis depends heavily on repetition. Players need to train consistently, build physical confidence and trust their movement before they can perform at their best under Grand Slam pressure. An injury that repeatedly interrupts that process can create problems far beyond the physical symptoms.

Although Tsitsipas won the ATP 250 title in Gstaad in July, his season remained inconsistent. His 25-19 win-loss record before the US Open reflected a player capable of producing strong performances but struggling to maintain them.

A major coaching change has added another dimension

Tsitsipas also made another significant change before the US Open by parting ways with his father, Apostolos Tsitsipas, as his coach.

The decision was not entirely straightforward. He had previously separated from his father before bringing him back, meaning their latest split represented another major adjustment in his professional setup.

He has now begun working with Patrick Mouratoglou, one of the most recognised coaches in professional tennis.

Whether the coaching change becomes a long-term solution cannot yet be determined, but the timing is interesting. Tsitsipas arrived in New York with a different mindset and fewer expectations, and the results have immediately improved.

His approach has also become more pragmatic. Rather than assuming every match will go according to plan, he has tried to prepare mentally for difficult situations.

Tsitsipas has adopted a mindset of preparing for difficult scenarios rather than expecting everything to unfold perfectly.

That approach may be particularly useful for a player returning from a period of physical and competitive uncertainty.

The underdog mentality may be helping Tsitsipas

For much of his career, Tsitsipas has been viewed as a serious Grand Slam contender. He has reached two major finals and was once a regular presence near the top of the rankings.

The current situation is completely different. He is unseeded and ranked outside the top 50, meaning opponents may not approach him with the same level of expectation.

That can work in his favour.

An underdog can sometimes play more freely because the pressure of protecting a ranking position or meeting tournament expectations is reduced. Tsitsipas appears to be embracing that role rather than fighting against it.

His next challenge is American eighth seed Ben Shelton, creating another difficult test. Shelton brings home support, powerful serving and a contrasting style that will challenge Tsitsipas in a different way from his previous opponents.

Medvedev is quietly rebuilding his confidence

While Tsitsipas has attracted attention because of his ranking decline, Medvedev’s resurgence is arguably just as intriguing.

The Russian arrived in New York as the world No.8 and seventh seed, but his recent form did not resemble that of a former world No.1 and US Open champion.

He had lost three of his previous four matches before the tournament. His form during the hard-court swing had raised questions about whether he could rediscover the level that made him one of the most difficult players to beat on the surface.

So far, the answer has been encouraging.

Medvedev defeated Arthur Rinderknech 6-4, 6-4, 6-4 in the third round and has not dropped a set throughout the tournament. Even more impressive is the fact that he has dropped serve only once across his three matches.

That statistic points to an important improvement. Medvedev’s game has traditionally been built around exceptional returning, court coverage and the ability to make opponents play one additional ball. Protecting his own serve consistently allows those strengths to become even more effective.

Medvedev’s season has already contained major highs and lows

Medvedev’s 2026 season began positively. He won titles in Brisbane and Dubai and reached the Indian Wells final, suggesting that another strong campaign could be developing.

However, the second half of his season brought a significant decline in results.

Like Tsitsipas, Medvedev also experienced coaching changes. He separated from longtime coach Gilles Cervara after a difficult period and later split with Thomas Johansson during the season.

Andrey Golubev was brought into his team for the Cincinnati tournament and the US Open.

The fact that Medvedev has responded immediately in New York makes the coaching situation an interesting storyline, although it would be premature to attribute his entire resurgence to one change.

Tennis performance is influenced by numerous factors, including confidence, health, tactical clarity and opponent matchups. A new coaching environment can help, but the player still has to execute under pressure.

Why Medvedev’s attitude toward form matters

Medvedev has taken a notably relaxed view of his recent fluctuations. Rather than treating poor form as evidence that his best tennis has disappeared permanently, he sees ups and downs as a normal part of sport.

That perspective may help explain why he has looked more comfortable in New York.

Players can become trapped by the expectation that every match must confirm their previous status. A former world No.1 may feel that anything short of dominance represents failure. Accepting fluctuations can instead allow a player to focus on the next point, game and match.

Medvedev illustrated this idea by comparing tennis form with baseball. Great players in other sports can struggle for a period before suddenly producing an extraordinary run of performances.

The comparison is simple but useful: temporary decline does not automatically mean permanent decline.

Tsitsipas and Medvedev share a surprising career pattern

The comparison reveals why their progress is so interesting. Their circumstances are different, but both experienced periods when early Grand Slam exits became increasingly common.

Both are also established title-winning players rather than emerging prospects. Together, they have appeared in seven Grand Slam finals and won one major, with Medvedev claiming the 2021 US Open title.

That history matters because neither player is learning how to compete at the highest level for the first time. They are attempting to rediscover something they already know how to do.

The US Open comeback story is about more than rankings

Rankings are useful indicators of consistency, but they do not always capture a player’s immediate level. Tsitsipas’ ranking had fallen sharply, yet his ability to defeat two seeded opponents shows why past achievements cannot simply be ignored.

Medvedev provides the opposite example. His top-eight ranking remained strong, but his recent performances had created doubts about his competitiveness.

The US Open has therefore demonstrated the difference between ranking position and current confidence.

A ranking is built over time. A Grand Slam match is decided in the present.

That distinction is particularly important in tennis, where a player can enter a tournament with poor recent results and suddenly find the rhythm necessary to win several matches in succession.

Why the fourth round could be a turning point

For both players, reaching the fourth round is valuable even before considering how far they eventually go.

Tsitsipas has already achieved his first fourth-round appearance at the US Open, while Medvedev has returned to that stage only for the second time since 2024.

Winning multiple matches at a major can restore more than ranking points. It can rebuild belief.

A player who has repeatedly lost early may begin questioning whether he can still handle the pressure of Grand Slam competition. Several consecutive victories can reverse that internal narrative.

That is why the second week of this US Open could become important for both players even if neither reaches the final.

A chaotic draw could make the comeback even bigger

The early exits of several top-10 seeds have made the tournament unusually open. That does not guarantee an easier path for Tsitsipas or Medvedev, because the remaining players still include dangerous opponents.

However, the reduced presence of highly seeded players changes the competitive landscape.

For Tsitsipas, the benefit is particularly clear. An unseeded player who has already defeated the 10th and 18th seeds has demonstrated that he can exploit an unpredictable draw.

Medvedev, meanwhile, has the experience of winning this tournament before. If his serving remains reliable and his return continues to create pressure, he possesses the knowledge required to handle the later stages.

What to watch next

• Tsitsipas vs Ben Shelton: The Greek will face the eighth-seeded American in another major test.
• Tsitsipas’ physical condition: His recent back problems make his ability to maintain intensity an important storyline.
• Medvedev’s serve: He has dropped serve only once in three matches, making that consistency a major strength.
• Medvedev’s coaching setup: His partnership with Andrey Golubev will remain under attention as the tournament progresses.
• The unpredictable draw: With several top seeds already eliminated, opportunities are opening for experienced and emerging players alike.

The bigger prediction: experience could become an advantage in New York

If the men’s draw remains as unpredictable as it has been through the opening rounds, experienced players could become increasingly valuable.

Tsitsipas and Medvedev have already experienced Grand Slam pressure, deep tournament runs and the emotional swings that come with competing for major titles. That knowledge cannot guarantee success, but it can help players navigate difficult moments.

Medvedev has already won the US Open, while Tsitsipas has reached two Grand Slam finals. Both understand what the second week of a major tournament demands.

Their challenge now is to convert renewed confidence into sustained performance.

Conclusion: Tsitsipas and Medvedev have given the US Open a new storyline

The 2026 US Open has already produced an unpredictable men’s draw, but the revival of Stefanos Tsitsipas and Daniil Medvedev has added an especially compelling storyline.

Tsitsipas arrived ranked 53rd after falling to a career low of 88 earlier in the year and carrying the burden of injury and inconsistent Grand Slam results. He has responded by defeating Arthur Fils and Jiri Lehecka and reaching the fourth round for the first time in New York.

Medvedev entered as the seventh seed and former world No.1 but had struggled for form before the tournament. He has responded with three straight-set victories and has dropped serve only once.

Their resurgence shows why careers in professional tennis cannot be judged solely by rankings or recent defeats. Confidence can return quickly, tactical changes can alter a player’s trajectory, and experienced champions can rediscover their level when expectations change.

With the tournament entering its second week, Tsitsipas and Medvedev are no longer simply comeback stories. They are legitimate threats in an increasingly open US Open draw, and their next matches will reveal whether this resurgence is a short-term spark or the beginning of a much bigger revival.
