Of all the sports in the world, tennis may have the strangest range of ages. Tennis players that are considered prodigies may begin their pro career at 13 or 14. By the time they hit 30 though, tennis players may be considered to be reaching the end of their careers.
The game is never stronger than when it features exciting young players barely in their teens and older established veterans who are still effective players. This list includes the best players who are either 21 years of age and younger of 35 years of age and older.
Alexei Popyrin – 19 Years Old
19-year-old Alexei Popyrin might be the best young player hailing from Australia. He had a very successful Juniors career that he capped by winning the 2017 Junior French Open.
Popyrin made some noise this year at his hometown Grand Slam, The Australian Open, where he reached the 3rd round, falling to Laslo Djere. The youngster has also qualified for his country’s Davis Cup team. He made his debut for the team in February of 2019.
Malek Jaziri – 35 Years Old
Like some of the other older players on this list, Jaziri has reached much of his success in the latter years of his career. The Tunisian moved up to 42nd in the world rankings in January of 2019.
Jaziri was able to reach the finals of the Istanbul Open in 2018, but dropped the match to Taro Daniel. His career has also featured controversial incidents in 2013 and 2015 when he was ordered by his government to not play against Israeli players.
Zachary Svajda – 16 Years Old
Zachary Svajda, from Pacific Beach in San Diego, California is the youngest professional tennis player based in the United States. The teen, who is a home-schooled High School Sophomore has been coached by his Father Tom for his entire career.
Svajda made waves by defeating Joao Lucas Reis Da Silva, an established tour pro, in the first round of the Claremont Classic in California. The teen, who currently only stands at 5-8, has a bright future in tennis ahead of him.
The next player regularly plays for South Korea’s Davis Cup team.
Kwon Oh-Hee – 41 Years Old
Like Roberto Menendez, South Korean player Kwon Oh-Hee has also continued his career into his 40’s. Oh-Hee has spent much of his career playing in tournaments all over Asia. He earned his best year-end ranking in 2005 when he finished 342nd in the World.
The South Korean has won a number of singles titles including events that took place in Indonesia, South Korea, and Japan. He also has a record of 3 wins against 1 loss in Davis Cup play.
Jannick Sinner – 17 Years Old
Jannick Sinner, who was born in Innichen, Italy is currently the top-ranked professional tennis player under 18 years of age. Since he turned pro in 2018, the Italian has quickly risen up the ranks and currently stands at the 209th ranked player in the World.
Sinner has gotten to that ranking by winning tournaments in the Italian towns of Trento, Pula, and Santa Cristina Valgardena. The baby-faced player should continue to be a huge factor in the years to come.
The next player hit one of the hardest serves in tennis history.
Ivo Karlovic – 40 Years Old
Ivo Karlovic, born in Zagreb, Croatia in 1979, may be one of the oldest players on the tour but he is still a force to be reckoned with. Known for his incredibly hard serve, Karlovic is one of only four players with over 10,000 aces.
The Croatian rode that 156 mph serve to quality showings in all 4 Grand Slam tournaments. He also won Laurels Tennis Academy as a member of Croatia’s 2005 Davis Cup championship team.
Andu Mukhtar – 14 Years Old
Mukhtar Andu from Great Britain holds the distinction of being the very youngest player on the ATP Tour. As his career is just getting started, Andu is currently ranked as the 1,575th ranked player on the World Tour.
It is likely that he will get much better and fast. Andu recently achieved his first tour victory with a 6-4 victory over Paul Emmanuel. His eventual success will be dictated by his ability to get his booming serve within the lines.
Luca Nardi – 15 Years Old
Luca Nardi is a baby faced, right-handed player who hails from Pesaro, Italy. He successfully navigated the World Junior Tennis system and quickly moved himself up to the professional ranks. He was able to achieve his first tour win at the age of 14.

Feliciano Lopez – 37 Years Old
Born in Toledo, Spain in 1981 Felciano Lopez is the first player on this list with a Grand Slam title to his name. In addition to that 2016 French Open doubles win, he also made the quarterfinals of the US Open and Wimbledon.
Along with partner Marc Lopez, he is still a threat to win any doubles tournament that comes around. When he’s not playing tennis, Feliciano also works as a model, appearing in campaigns for Hugo Boss and Elle.
Felix Aujer-Aliassime – 18 Years Old
While Felix Aujer-Aliassime will not turn 19 until early August, he has already accomplished much in his young career. The Canadian youngster was very successful on the Juniors tour, winning the 2016 Junior US Open and reaching the finals of the 2016 Junior French Open.

The Italian-born player won his first ATP Title in 2016 when he defeated Nikoloz Basilashvili to capture the 2016 Austrian Open. Lorenzi finished 2018 still in the top 100, ranking in at 94.
