Ten Oldest Men’s Singles Tennis Players in the Top 100

Professional tennis is a physically demanding sport, and players competing in singles must maintain peak fitness levels to perform at their best. However, due to the intense physical strain and the grueling demands of the tennis calendar, many players often retire earlier than expected. 

Despite this, there are a select few who defy the conventional notion of age in sports, embodying the adage “Ageing like fine wine” or “Old is Gold.” These players continue to maintain exceptional fitness and form, winning tournaments and making deep runs in Grand Slams, often causing upsets against younger, higher-ranked opponents. Their enduring success is a testament to their resilience, discipline, and commitment to excellence, showing that age is not always a barrier to greatness in sport.

Let’s take a look at the Ten Oldest Singles Tennis Players ranked inside the ATP Top 100 – 

Gaël Monfils (FRA, 38 years old)

Gaël Monfils is an exceptional example of ageing players still going strong. His exceptional run at this year’s Australian Open has been ample proof of his ability to still compete at the top. He is currently ranked World No. 41 in the ATP Singles Rankings.  

Monfils made his Professional debut in 2004 and has gone on to win 13 ATP Singles titles. He also reached two Grand Slam Semi-finals (French Open, 2008 and US Open 2016). In addition, he also has Junior Grand Slam titles at Australian Open, French Open and Wimbledon, all in 2004 which also help him garner the Juniors No.1 ranked player in the world. 

Monfils recent run at the 2025 Australian Open was incredible where he reached Round Four beating two higher ranked players, showcasing his resilience, skill and fitness. He has been one of the most agile players and one of the most exciting players to watch over the years and still going deep in ATP and Grand Slam tournaments at this age. 

The Frenchman is a prime example of fitness, incredible skill, and a never-say-die attitude—qualities that young kids can look up to and strive to emulate.

Novak Djokovic (SRB, 37 years old)

Novak Djokovic needs no introduction in Tennis. The Serbian has been widely regarded as the best player to ever play the game and he isn’t d.one yet. The 24-times Grand Slam Champion is one of the three players to complete a Golden career Grand Slam after winning the Olympic Gold in the Men’s Singles at the Paris Olympics last year. 

Even though Djokovic is in the twilight of his career and his speed and agility are no longer his strengths when he has to compete against younger and more quicker players, the World No. 7 is still a force to be reckoned with.

In his quest to get past Margaret Court and gain Tennis immortality with a record 25 Grand Slam Singles Titles, he is currently in the Quarter-Finals of the Australian Open and still in contention to win ATP and Grand Slam majors. Djokovic was under a lot of pressure last season, not having won a single Grand Slam or ATP Masters but he is playing exceptional so far. 

Into the Semi-finals of the ongoing Australian Open, he is a title contender for sure and will definitely be contesting for the rest of the major tournaments in 2025. 

Despite age and fitness challenges catching up to him, Djokovic remains one of the top contenders on the Men’s tour, defying both injury setbacks and the passage of time with his exceptional skills and unyielding mentality.

Fabio Fognini (ITA, 37 years old)

Fabio Fognini has been another stalwart of the game who has brought a lot of pride to his nation. 

Fognini started his career in 2005 and has so far won 8 career titles and a Doubles Australian Open title in 2015. His best Singles performance in a grand slam is a Quarter-final at the French Open in 2011. He has a preference for the clay surface and most of his career titles have been either on Hard or Clay surfaces.

Currently ranked 88 in the ATP ranking due to loss of form and injuries in 2023-24, the Italian had a career high ranking of No. 9 in 2019. 

He was due to play at this year’s Australian Open but pulled out due to undisclosed reasons. The Italian is a temperamental player but possesses flair, speed and movement on court. 

Since Fognini plays the Doubles as well, it remains to be seen how long he can keep up with playing the Singles. 

Roberto Bautista Agut (ESP, 36 years old)

Spanish veteran Roberto Bautista Agut is another player who continues to play in the Men’s Singles draw at the age of 36.

Bautista Agut turned pro in 2005 and had a highest ranking of World No. 9 in Nov, 2019. He has 12 career titles and his best result in a grand slam is a Quarter-Finals appearance in the Australian Open in 2019. He also won the Davis Cup with Spain in 2019. He is currently ranked World No. 53 on the ATP rankings.

Bautista Agut plays with a counter-punching technique with a decent all-round game. He is still a dangerous opponent and he is able to play offensively with his forehand but thrives off his defensive ability with his consistency and quickness around the court.

Bautista Agut is still playing at a fairly decent level and has maintained his fitness to still compete well at the Grand Slams and other ATP Tournaments. 

Adrian Mannarino (FRA, 36 years old)

Adrian Mannarino is another tennis player who has maintained longevity in the sport. The Frenchman is proving the old adage of ‘Ageing like fine wine’. He is also a very entertaining player to watch on a tennis court.

Mannarino has five ATP Tour Singles titles. Currently ranked World No. 75, the Frenchman rose to his highest ranking to World No. 17 in January, 2024. He had a superb 2023 and 2024 seasons helping him climb up the rankings and make it to Top 20. His best result at a grand slam tournament is a 

Mannarino is a left-handed defensive baseline and counter-punching player. His service is a solid weapon and even for a 36-year-old his agility and court-coverage are still quite good. Mannarino beat Ben Shelton at the Australian Open last year marking his second fourth round appearance at the Australian Open. He has also made it to the Wimbledon fourth round three times as well. 

On the back of a decent last season, it would be interesting to see how he fares in 2025. 

Kei Nishikori (JPN, 35 years old)

Kei Nishikori is another well-known name around the tennis circuit. The 35-year-old Japanese player has caused some major upsets in his time. 

Nishikori is the only Japanese men’s player in the open era to be ranked in the Top 5 of the ATP Men’s Singles ranking which he achieved when he was ranked World No. 4 in March, 2015. Nishikori has 12 career ATP titles and has a catalogue of impressive Grand Slam performances too. Nishikori’s best Grand Slam performance is a Finals appearance at the US Open in 2014 and he has made it to Quarter-Finals of Australian Open, French Open and Wimbledon as well that too multiple times. He also won an Olympic Bronze in 2016.

At the ongoing Australian Open, he lost to Tommy Paul in the second round. He had been competing well in major tournaments until 2019 but lost his way since then. He is currently ranked World No. 76 and has gotten back to competing in grand slams and ATP majors. The Japanese player is a defensive baseline player who likes to stretch rallies before going for winners. He has powerful and accurate groundstrokes both on the forehand and the backhand. 

Kei Nishikori is definitely not the same level as his Top-five ranking days, but he is still very much capable of causing upsets due to his consistent play from the back of the court. 

Jan-Lennard Struff (GER, 34 years old)

Jan-Lennard Struff is a German veteran who continues to play Men’s Singles at 34 years old. 

Struff turned pro in 2009 and managed his highest ranking of World No. 21 in June 2023. He is both a Singles and a doubles player and has won 1 ATP Singles and 4 ATP Doubles titles. His best result at a Grand Slam is a fourth-round appearance at the French Open twice. He also has a Semi-final appearance in Doubles at the Australian Open in 2018. In addition, he was a Semi-finalist in the Davis Cup with Germany in 2024. 

Currently ranked World No. 43, the German lost to Félix Auger-Aliassime in four sets at the ongoing Australian Open. The strong-serving German looks fit enough to compete in major tournaments. Struff is strong from the baseline and can dictate play from the back of the court on both sides. He likes to serve and volley which makes him a dangerous opponent still. 

He can definitely play and perform consistently on the ATP tour for a few more years without a doubt.   

Dušan Lajovi? (SRB, 34 years old)

Dušan Lajovi? is a Serbian Tennis player that has been a regular on the Men’s tour for a long time now. 

Lajovi? turned pro in 2007 and reached his highest ranking of World No. 23 in September 2020. He has 2 career ATP titles and has also made it to an ATP Masters 1000 final when he reached the finals of Monte-Carlo Masters in 2019. His best grand slam performances have come at the French Open and the Australian Open where he managed to reach the fourth round. He has also made it to a French Open Quarter-finals in the Doubles. He has also beaten a couple of Top 10 players like Jannik Sinner, Andrey Rublev and Novak Djokovic in ATP Tour matches in 2023. He also qualified for the Paris Olympics 2024.

Lajovi? is currently ranked World No. 80 but even in the 2024 season, he beat many top-ranked players like Félix Auger-Aliassime, Ugo Humbert and Arthur Fils and therefore, he is not an easy opponent to deal with. The Serbian has an affinity for the clay surface and likes to play dominant tennis from the back of the court. 

He can still be a tricky adversary as he has proven by beating many higher-ranked and younger players on tour. 

David Goffin (BEL, 34 years old)

David Goffin is another old-timer in Men’s Singles Tennis. The Belgian has been on the ATP tour for a long time and continues to put in strong performances. 

Goffin turned pro in 2009 and rose to his highest ranking to World No. 7 in the Men’s Singles ATP Rankings in November 2017. Goffin is the highest ranked Belgian Men’s player in the history of the game and is still the No. 1 Belgian tennis player. Goffin has 6 career ATP titles. His best performances as a Grand Slam have been multiple Quarter-Finals appearances at the Australian Open, French Open and Wimbledon. He has also been a Davis Cup finalist with Belgium in 2015 and 2017. 

Goffin lost in the first round of the ongoing Australian Open but he has been a consistent player over the years. Currently ranked World No. 53, the Belgian is a tough opponent. He is a predominantly baseline player with powerful groundstrokes and one of the best two-handed backhand down-the-line shots on tour.  

At 34, he continues to prove that age is just a number, maintaining both consistency and fitness to give his younger opponents a run for their money.

Grigor Dimitrov (BUL, 33 years old)

Grigor Dimitrov is still a very popular name on the Men’s tour in Tennis. The 33-year-old Bulgarian is a stalwart of the game and even though injuries have crept up from time to time, he still has the skills and the mentality to beat even a Top 10 opponent. 

Dimitrov turned pro in 2007 and reached a career highest ranking of World No. 3 in November 2017. Dimitrov was a child prodigy in tennis and had gained massive popularity after winning the Junior Boys’ Singles titles at the 2008 Wimbledon and 2008 US Open, also becoming the World No. 1 Junior Boys’ player. He has 9 ATP career titles and his best Grand Slam appearances have been reaching the Semi-finals at the Australian Open, Wimbledon and US Open. His best performances have been winning the year-ending ATP Masters Finals in November 2017. 

Currently ranked World No. 10, the Bulgarian Grigor Dimitrov is renowned for his athleticism, hustle, and exceptional shot-making abilities. However, injuries have been taking a toll on him recently, with his latest setback coming at the ongoing Australian Open, where he was forced to retire in the first round.

It will be interesting to see whether he can recover from these recurring injury issues and play regularly this season, or if it might be time for him to seriously consider retirement.
