Joao Fonseca vs Miomir Kecmanovic Match Preview

Set for their first meeting on the ATP Tour, both Fonseca and Kecmanovic are bidding to win their second title of the season. Ranked #45 and #42 respectively, they are two of the most potent unseeded talents in the men’s draw. Having announced himself by winning the 2024 Next Gen ATP Finals, Joao Fonseca started 2025 by winning the Argentina Open in February. The 19-year-old also excelled on the Challenger Tour, before reaching the Roland Garros Round of 32.

Kecmanovic and Fonseca also reached the Third Round of the Wimbledon Championships. The Serbian started 2025 by reaching the semis in Adelaide. He then pulled off a magnificent double in Delray Beach – winning the singles and doubles trophies. Since then, the 25-year-old is yet to string a consistent set of outings. While Fonseca has a 9-5 hard court record (80% success rate in service games), Kecmanovic is not far behind with his 14-10 statistic (80% success rate in service games).

Joao Fonseca vs Miomir Kecmanovic US Open 2025 Prediction

While Fonseca has a great ball-striking ability, the criticism of his game remains that it is too uni-dimensional. When the pressure is applied back on him, he tends to run out of answers and the unforced errors begin creeping in. At the Cincinnati Open, the teenager managed to maintain a first serve percentage of just under 70%. While Kecmanovic has a strong forehand, Fonseca can dismantle his game by making him move front and back, and staying strong on serve.

Prediction: Joao Fonseca in five sets.
