Many of the year’s most memorable upsets came on the Grand Slam stages, including big wins from a home favourite at the Australian Open and a pair of rising stars at the US Open.

As we continue to look back at the 2023 season, ATPTour.com counts down the five biggest shocks at the majors this year — all of which came in five sets.

5) Roland Garros R1, Seyboth Wild d. Medvedev 7-6(5), 6-7(6), 2-6, 6-3, 6-4
Brazilian qualifier and Roland Garros debutant Thiago Seyboth Wild scored his first Grand Slam main-draw win in style with a upset of second seed Daniil Medvedev — who entered on a six-match clay-court winning streak after claiming his first tour-level title on the surface in Rome.

Coming into the match at No. 172 in the Pepperstone ATP Rankings, an aggressive Seyboth Wild made a dream start and held two set points for a two-set lead. But after cramping earlier in the second set, the 23-year-old could not prevent Medvedev from levelling the match and storming through set three soon after.

Undeterred, Seyboth Wild rediscovered his attacking game to surge through the final two sets. After four hours, 15 minutes, he closed out the upset with a big forehand winner, finishing with a 69 per cent win rate (38/55) on net points.

“I have watched Daniil play for my entire junior career, up until today. Playing on this court against this kind of player and beating him is a dream come true,” said the Brazilian. “Walking on court I just wanted to get to the net as much as possible and use my forehand against his and it worked pretty well.”

Seyboth Wild won four ATP Challenger Tour titles in 2023 — two either side of Roland Garros — and reached a career-high Pepperstone ATP Ranking of No. 74 in September.

What an upset! 🤯

4) US Open R2, Zhang d. Ruud 6-4, 5-7, 6-2, 0-6, 6-2
Zhang Zhizhen continued his rapid rise on the ATP Tour with a helping of Grand Slam revenge against returning US Open finalist Casper Ruud.

Earlier in the season, the Chinese star was beaten by Ruud at Roland Garros, where the Norwegian reached the final for the second straight year. But Zhang ensured there would be no repeat final run for Ruud in New York by notching the biggest win of his career against the fifth seed.

With the help of 59 winners, including 18 aces, Zhang became the first Chinese man to earn a Top 5 win since the start of the Pepperstone ATP Rankings in 1973. By riding his powerful forehand and serve, Zhang made up for his US Open heartbreak in 2022, when he missed out on seven match points in a first-round defeat to Tim van Rijthoven.

“Last year at the US Open, I can say it was a bad memory. But this year is a little bit different,” said the 27-year-old, who went on to finish the season inside the Top 60.

3) Roland Garros R1, Altmaier d. Sinner 6-7(0), 7-6(7), 1-6, 7-6(4), 7-5
In a five-hour, 26-minute marathon, Daniel Altmaier saved two match points in the fourth set before Jannik Sinner erased four in the match’s final game. The German claimed the first five-set win of his career by serving out the victory at the second time of asking, ending the Roland Garros run of the in-form eighth seed, who reached the semi-finals in Monte-Carlo and the quarters in Barcelona.

Altmaier showed nerves of steel to save 15 of 21 break points and supreme endurance to recover after Sinner appeared to take command of the match in a one-sided third set. The victory also avenged a five-set defeat to the Italian in the pair’s only previous Lexus ATP Head2Head meeting at the 2022 US Open.

“The competition says it all,” Altmaier said after moving on to the third round in Paris for the second time. “We’ve had historic matches with so many match points… I don’t know if you can call this an ‘historical’ match, but I think it was one to remember.”

2) Australian Open R2, Popyrin d Fritz 6-7(4), 7-6(2), 6-4, 6-7(6), 6-2
There was a wave of American success this year in Melbourne, but on his home turf, Alexei Popyrin made sure Taylor Fritz did not join the party. The fiery Aussie scored the standout shock of an upset-filled Australian Open with a big-serving display in Melbourne — a result made all the more surprising by the opponents’ contrasting fortunes in the previous season.

Popyrin earned just five tour-level wins in 2022 but kickstarted the new campaign with his fourth Top 10 win and his second at the Australian Open (d. Dominic Thiem in 2019). Behind 19 aces, Popyrin reached the third round for the third time at his home major. He faced just two break points in a match of razor-thin margins — one in the fourth and fifth sets — and recovered after missing out on a match point in the fourth-set tie-break.

“This is the dream for me, and I don’t want to wake up at all,” he said in an emotional on-court interview. Just before that, he addressed the crowd as they chanted his name: “You guys were just incredible. Oh my god, this is crazy. I really couldn’t have done it without you guys. This win means so much to me.”

1) US Open R2, Stricker d. Tsitsipas 7-5, 6-7(2), 6-7(5), 7-6(6), 6-3
On the same day as Zhang’s Ruud upset, Dominic Stricker scored his maiden Top 10 win to add to Stefanos Tsitsipas’ US Open woes. The 21-year-old qualifier, who capped his breakthrough season at the Next Gen ATP Finals presented by NEOM, advanced to the third round at a major for the first time with a gutsy performance in his New York main-draw debut.

In a four-hour, 10-minute epic, the lefty battled back from 3-5 in the fourth set and played his best tennis down the stretch to keep the seventh-seeded Tsitsipas in search of his first US Open fourth-round appearance. Stricker lost just four points on his first serve (19/23) in the final set and struck 78 winners in the marathon match.

“I came out today pretty well. I felt good from the first set on. It was a tough battle but I am just super happy right now,” said Stricker, who rose from World No. 128 in New York to a year-end finish inside the Top 100 of the Pepperstone ATP Rankings. “I was down 3-5 and then I came back in the fourth set. I don’t know how, but I did it somehow and then I kept playing very high level tennis. I am a bit speechless but it is a great day.”

Jannik Sinner has capped his career-best ATP Tour season in style after being voted the Fans’ Favourite singles player in the ATP Awards.

The 22-year-old Italian won four tour-level titles in 2023, including his maiden ATP Masters 1000 crown in Toronto. He also reached the Nitto ATP Finals title match, his first major semi-final at Wimbledon and led Italy to its first Davis Cup trophy since 1976.

Sinner, who held a 64-15 tour-level record in 2023, finished the season at a career-high No. 4 in the Pepperstone ATP Rankings, becoming the first Italian man to end a season in the Top 5.

The result will delight Sinner’s fan club, ‘The Carota Boys’, who have become famous in the tennis world for showing up at tournaments in carrot costumes. The act stems from a changeover in Vienna in 2019 when the Italian chowed down on a carrot.

Sinner, who won Newcomer of the Year in 2019, has been nominated for two player-voted ATP Awards this season: Most Improved Player of the Year and the Stefan Edberg Sportsmanship Award. The Italian’s coaches, Darren Cahill and Simone Vagnozzi, are up for Coach of the Year award. Winners will be revealed throughout Awards Week. 

Roger Federer won the Fans’ Favourite award a record 19 times. Spaniard Rafael Nadal won the award for the first time in his career last year.

The announcement of Sinner’s win comes a day after Karen Khachanov and Andrey Rublev were named the Fans’ Favourite doubles team.

Sportradar and Tennis Data Innovations (TDI), a specialist joint venture vehicle of ATP and ATP Media, have entered into a multi-year agreement providing the sports technology company with global data and streaming rights for betting, and media data rights, for all ATP Tour and ATP Challenger Tour events. The partnership will focus on driving commercial growth for the sport and enhancing fan engagement opportunities for the downstream market through the development of new betting and media products.

Sportradar will also work with TDI to create products for media, showcasing more in-depth statistical analysis and insights to inform and entertain fans, as well as utilize Sportradar’s OTT solution to stream live match coverage of the ATP Challenger Tour, via ATP’s Challenger TV. Additionally, the creation of a joint Tennis Innovation Lab will address emerging opportunities to support ATP’s vision to establish tennis as the most technologically advanced sport in the world.

Sportradar will supply Integrity Services for all ATP Tour and ATP Challenger Tour events to safeguard competitions against the threat of betting-related match fixing and corruption, including monitoring and addressing integrity threats and risks through due diligence and investigation support.

David Lampitt, TDI CEO, said: “This is a landmark opportunity to realise our growth ambitions and deliver on our commitment to take the fan experience to the next level.

This will allow us to effectively monetize the relationship, while delivering new ways for bettors and fans to experience the sport of tennis.”

Rafael Nadal’s return to the ATP Tour is drawing ever nearer, and the road toward his comeback at the 2024 Brisbane International presented by Evie, which takes place from 31 December to 7 January, included a stop in Kuwait.

Nadal travelled to the Rafa Nadal Academy in Kuwait, which opened in 2020 at the Sheikh Jaber Al-Abdullah Al-Jaber Al-Sabah International Tennis Complex. There, he shared a training session with Arthur Fils, the 19-year-old Frenchman who recently reached the title match at the Next Gen ATP Finals presented by NEOM.

“It’s great to be here in Kuwait to train for a few days. Everyone has been so welcoming. Thank you for everything,” wrote the Spaniard on his official social media accounts.

The Mallorcan travelled to Kuwait in search of temperatures and conditions similar to those he will find in a few weeks in the Australian summer.

Nadal, surrounded by his team, shared an image on social media of one of his habitual group activities, a game of ludo with Carlos Moya, Marc Lopez and his physio Rafael Maymo.

The Spaniard, who recently posted a message of cautious excitement about his return, is preparing to compete for the first time since he took to the court on 18 January this year, in the second round of the Australian Open against Mackenzie McDonald.

“I still think what I said in the last press conference, that I do not deserve to end my sports career in a press room.” he said. “I would like to finish in a different way, and I have fought and kept the illusion for that to happen, with doubts, with bad moments, very bad or better moments.”

Jose Higueras, who worked with ATP Tour greats like Pete Sampras, Jim Courier, Roger Federer and Michael Chang during his coaching career, has been named the recipient of the Tim Gullikson Career Coach Award in the 2023 ATP Awards. 

The Spaniard coached Chang to his 1989 Roland Garros title, when the American was 17, and also spent time with Americans Jennifer Capriati and Mary Joe Fernandez.

The 70-year-old Spaniard, who also worked with USTA Player Development, has been selected as the third winner of this award, following in the footsteps of Australians Tony Roche (2019) and Bob Brett (2020). The recipient exemplifies excellence, leadership, respect, and a true love for the sport of tennis and the art of coaching.

Named after the late Tim Gullikson, the award showcases someone who has inspired generations of young players and fellow coaches to grow the sport of tennis.

Higueras, who reached a high of No. 6 in the Pepperstone ATP Rankings as a player, won 16 ATP singles titles and reached the Roland Garros semi-finals in both 1982 and 1983. He also received the ATP Sportsmanship Award in 1983.

French media outlet L’Équipe has been recognised with the Ron Bookman Media Excellence Award in the 2023 ATP Awards.

“It is a great honour for us, the journalists of L’Équipe, to receive the Ron Bookman Media Excellence Award from the ATP,” L’Équipe said. “Winning the award for the third time, after 1999 and 2010, suggests that the baton is being passed from one generation of journalists to the next.”

Recognised for excellent coverage of tennis on all their platforms (newspaper, magazine, digital, TV), L’Équipe prides themselves in being present on the Tour all year round, boasting a list of writers whose sole focus is tennis reporting: Lucile Alard, Vincet Cognet, Bertrand Lagacherie, Romain Lefebvre, David Loriot, Quentin Moynet, Franck Ramella and Julien Reboullet. Journalists Anne-Sophie Bourdet and Bruno Garay also play a key role for the magazine.

“Our commitment is to covering tennis as well as possible and be consistent in an attempt to write about everything that makes this sport so complex, from the game itself such as technique, tactical evolution, and history to the human side of the game,” L’Equipe said. “We appreciate the fact that we are receiving this award collectively, because it is a real ‘Equipe’ [team] effort throughout each season.”
