Tennis's teenage invasion has arrived in full

Since 2022, tennis has lost its most iconic stars at a rate of one per year. First was Serena Williams, and then Roger Federer and Rafael Nadal. Many worried what the future of tennis would look like,

In 2025, the future is here, and fans can be comforted in knowing the game is in good hands. Joao Fonseca, Mirra Andreeva, Alexandra Eala, and Learner Tien, ranging in age from 17 to 19, are ready for their big moments.

Let's get to know each one a little better and understand where they are in their maturity and readiness to win big titles.

These players are leading the way to tennis's teen invasion

Joao Fonseca

Brazilian Joao Fonseca, 18, is a bonafide superstar. He fills tennis stadiums wherever he plays. Brazilian fans are giving tennis a World Cup socer atmosphere with their loud cheers and enthusiam.

He is not just beloved by Brazilians. Fonseca is a worldwide phenom. He turned professional in 2024 after turning down a college scholarship to play tennis at the University of Virginia. He already has one million followers on his Instagram account.

Fonseca has big energy and a monstrous forehand. Retired tennis pro Jim Courier described the spin and velocity of his forehand as greater than Rafael Nadal's in his prime. He challenged Alex de Minaur in Tuesday night's Miami Open third round match, but de Minaur prevailed partly because Fonseca seemed to lose energy in the middle of the match. Conditioning and shot-making will get even better, which means Fonseca will be a force to reckon with sooner rather than later.

Mirra Andreeva

Mirra Andreeva, who turns 18 on April 29, is already a household name at 17. 2025 has been a dream season for her with two WTA 1000 titles in 22 days at Dubai and Indian Wells.

Andreeva has a legendary coach in Conchita Martinez who will help her even more. She has great instincts, plays well on every surface, and has shown her grit in wins over the top players in the world.

Mirra Andreeva is the teenager most likely to win a Grand Slam, and it could happen as soon as Roland Garros. She beat Aryna Sabalenka at last year's French Open and made it to the semifinals.

Alexandra Eala

19-year-old Filipina tennis player Alexandra Eala is a new name for tennis fans. She is having her breakout tournament at the Miami Open with wins over Jelena Ostapenko and Madison Keys. Eala will play the biggest match of her career on Wednesday when she faces World No. 2 Iga Swiatek, a player she knows well, because she presented her high school diploma to her at the Rafael Nadal Academy.

Eala is a lefty with a strong forehand and nothing to lose. She plays with confidence, grace, and gratitude, pledging to enjoy the moment but vowing that she is just getting started.

She is also putting the Philippines on the tennis map, a country best known for boxing because of superstar Manny "The Pacman" Pacquiao.

Learner Tien

Learner Tien, the 19-year-old American whose parents emigrated from Vietnam to California before his birth, has a calming presence on the tennis court.

Tien faced Fonseca in the Miami Open first round and handled the Brazilian crowd well. He does not have Fonseca's power, but he has precision shotmaking and an intelligence on the court. Tien also has a sense of humor. On his Instagram post after the Miami loss to Fonseca, he listed his location as Rio de Janeiro because the Miami Open crowd certainly made it seem that way.

Tennis's teenagers have injected excitement into the game at a time when the legends are departing.
