Four teenagers will line up in the first round at Wimbledon in 2025 with rising Brazilian sensation Joao Fonseca the youngest player in the main draw while Jakub Mensik is the highest-ranked of the young stars.

Mensik can also be considered a veteran among the youngsters as he will make his sixth appearance in a Grand Slam main draw when he features at Wimbledon.

The 7 youngest women in the Wimbledon main draw:

7. Ethan Quinn- 21 years and three months

American Quinn made his Grand Slam debut as a teenager at the 2023 US Open and he won his first major match at this year’s French Open when he overcame 16th Grigor Dimitrov in the first round before losing in the third round.

The 21-year-old started the French Open at No 106, but broke into the top 100 after the tournament and has since peaked at No 89.

Quinn will make his Wimbledon debut and he will take on fellow youngster Henry Searle at the All England Club.

6. Alex Michelsen – 20 years and 10 months

Michelsen turned pro in 2023 and he made his ATP debut in June and a couple of months later he reached his maiden final as he fellow American John Isner in the semi-final to set up a clash against Adrian Manarrino, but he lost in straight sets.

He jumped from No 190 in the rankings to No 150 on the back of that result and not long after he made his Grand Slam debut at the 2023 US Open, winning his opener before going down in the second round.

Michelsen reached two more finals in 2024, but lost on both occasions.

After finishing last year at No 41, the American started 2025 by upsetting 11th seed Stefanos Tsitsipas in the first round of the Australian Open. He went on to produce his best Grand Slam result as he reached the fourth round.

Michelsen will make his second appearance at Wimbledon, but will hope to claim his first win when he faces Miomir Kecmanovic.

5. Nishesh Basavareddy – 20 years and one month

American Basavareddy only turned professional in December 2024 and his ATP Tour debut came in 2025 at the Brisbane International and not long after that event he won his maiden top-level match as he reached the semi-final of the ASB Classic in Auckland, jumping into the top 100 of the rankings.

He was handed a big match on his Grand Slam debut as he faced the legendary Novak Djokovic first up and he managed to win a set before going down in four sets.

Basavareddy made his top 100 debut in May 2025 and will make his first appearance at Wimbledon, facing compatriot Learner Tien.

4. Jakub Mensik – 19 years and nine months

Czech star Mensik’s first taste of Grand Slam action came at the 2023 US Open when he reached the third round after coming through qualifying. Having started the year at No 408 in the rankings, he finished that season at No 167 and it was no surprise when he cracked the top 50 in 2024.

His maiden win at the majors came in the first round of the 2025 Australian Open and he followed it up with a big scalp as he stunned fifth seed Daniil Medvedev in the second round before eventually losing in the fourth round.
