Rising Star Fonseca Stuns Rublev in Australian Open upset
Joao fonseca, an 18-year-old Brazilian tennis sensation, delivered one of the biggest upsets of the 2025 Australian Open, defeating ninth-seeded Russian Andrey Rublev in a thrilling first-round match. The victory marks Fonseca’s first-ever Grand Slam win and solidifies his status as a rising star in the tennis world.
Fonseca, a qualifier for the tournament, showcased remarkable composure and skill, outplaying Rublev in straight sets: 7-6 (1), 6-3, 7-6 (5). The young brazilian credited the roaring support of the Brazilian fans for fueling his performance.”It was an astonishing experience playing on such a massive court,” Fonseca shared. “The energy from the crowd was amazing, and I truly enjoyed every point.”
This victory extends Fonseca’s remarkable winning streak to fourteen matches, a testament to his recent dominance on the court. In 2024, he captured the Next Gen ATP Finals title, going undefeated throughout the tournament. He followed that success with a string of victories, including the ATP Challenger Tour event in Canberra just weeks before the Australian Open.
Fonseca’s powerful serve, reaching speeds over 210 km/h, proved to be a major weapon against Rublev. He fired 14 aces and committed only one double fault, demonstrating exceptional control and precision. Fonseca remained focused on his own game, refusing to be intimidated by his opponent’s ranking. “I didn’t want to put too much pressure on myself,” he explained.”I just concentrated on playing my best tennis, and it paid off.”
Rublev, a former Australian Open quarterfinalist, struggled to find his rhythm throughout the match. He entered the tournament after a disappointing end to the 2024 season, suffering three consecutive losses in the group stage of the ATP finals. His early exit from the Hong Kong Open, where he was defending his title, further highlighted his recent struggles.
Fonseca’s next challenge will be against Italian Lorenzo Sonego, who upset veteran Stan Wawrinka, the 2014 Australian Open champion. The young Brazilian will be looking to continue his impressive run and make a deep push into the tournament.
