Grandstand Showdown as Fonseca Targets US Open Breakthrough
Round-1 at the 2025 US Open on Grandstand Court will feature a high-upside clash between Joao Fonseca of Brazil and Miomir Kecmanovic of Serbia. Fonseca, 19, is set to make his US Open main-draw debut on the Grandstand surface, taking on the 25-year-old former Wimbledon quarterfinalist in a match that could light up Flushing Meadows.
Fonseca arrived in New York with a rising profile after a breakout 2024 season culminated by winning the Next Gen ATP Finals. He continued his ascent in 2025 with the Argentina Open title in February and solid Challenger Tour form, plus a run to the Roland Garros Round of 32. On the court, he’s shown a capable hard-court game with a strong service presence, posting a solid hard-court record this season (around 9-5) and maintaining a service hold rate near 80 percent.
Kecmanovic, ranked a few spots higher in the current standings, also arrives with notable achievements. The Serbian reached the Wimbledon third round and produced a standout performance at Delray Beach, winning both the singles and doubles titles in one tournament, while opening 2025 with a semifinal showing in Adelaide. His overall hard-court ledger this year sits around 14-10, aided by a reliable forehand and steady first serves. The two players have never met on the ATP Tour before this Round-1 matchup.
Head-to-head will count for little in this first-time meeting, but the numbers suggest a tightly contested battle. Fonseca brings a high-pressure serve and aggressive ball-striking profile, while Kecmanovic will look to push the pace with his forehand and steady court positioning. Fonseca’s ability to sustain a high level of serve and stay aggressive under pressure will likely be a key theme if he’s to post the upset on the big stage.
Official betting markets list Fonseca as a slight favorite, with odds around 3/5, implying roughly a 60 percent probability by the bookmakers. If Fonseca can win a higher percentage of first-serve points and keep Kecmanovic moving to both wings, there’s a path for a five-set clash that could tilt in the Brazilian’s favor as the match wears on.
Bottom line: this is a coming-out party moment for Fonseca on a Grand Slam stage, and a strong opening would cement him as one of the sport’s bright young talents to watch in the season’s second half. For fans and bettors alike, the match promises high-energy tennis and the potential for a defining early-round upset.
In brief, Fonseca has momentum from a breakout year and a chance to prove he belongs among the sport’s next generation by taking down a solid veteran on the sport’s biggest stage.
