Joao Fonseca is rapidly climbing the ATP rankings. At just 18 years old, he made history on Sunday by becoming the tenth-youngest player to win an ATP title in the Open Era, skyrocketing from No. 99 to No. 68 in the men’s singles rankings as of February 17.
Fonseca now proudly holds the title of the youngest South American ATP champion in 38 years and stands as Brazil’s top-ranked player.
This week, he will compete in the 500-level tournament in Rio, going head-to-head with Alexandre Muller in the opening round.
Notably, Fonseca is the only player under 19 to be featured in the ATP’s Top 350.
In the Buenos Aires semifinals, Fonseca triumphed over Laslo Djere, who is also making waves this week with his return to the Top 100, climbing 14 spots to No. 98. Djere, a former world No. 27, is ready to make his mark once again.
Another Serbian star, Miomir Kecmanovic, also ascended 14 positions after a spectacular win over Alejandro Davidovich Fokina in the Delray Beach final, where he saved a pair of championship points. Davidovich Fokina’s impressive performance returned him to No. 50, up ten spots.
Medjedovic Achieves Career High (+23)
Hamad Medjedovic is shining bright this week for Serbian tennis, reaching his second ATP final in Marseille and soaring 23 spots to a personal best of No. 73.
Marseille champion Ugo Humbert also enjoyed success, moving up three spots to No. 14 after snatching his seventh career title, just shy of hitting his personal peak.
In exciting news, American Alex Michelsen (+4 to No. 33) and Spain’s Pedro Martinez (+4 to No. 37) have both hit new career-high rankings.
Among players yet to turn 21, Michelsen ranks second highest behind Arthur Fils, who stands at No. 21.
Sinner Surpasses Alcaraz in Weeks at No. 1
Jannik Sinner is celebrating his 37th week at the top of the ATP rankings, overtaking Carlos Alcaraz in total weeks at No. 1. Sinner now reclaims the 16th spot on the all-time list and is closing in on Ilie Nastase (40 weeks), Andy Murray (41), and Gustavo Kuerten (43).
