Daniil Medvedev broke his racket in anger after his first round loss.
NEW YORK, NY — The 2025 US Open is shaping up to be one of the most volatile Grand Slam tournaments in recent memory, with nearly every round providing a fresh on-court confrontation that has shifted the focus from aces and winners to sportsmanship and simmering tensions.
From heated net exchanges to public feuds, Flushing Meadows has become a cauldron of controversy, prompting players to openly debate why tempers are running so hot in the Big Apple.
The latest incident saw Spain’s Jaume Munar confront Belgium’s Zizou Bergs after their third-round match on Saturday, accusing him of intentionally loud grunting. The exchange concluded with Bergs denying the accusation and Munar ultimately accepting the explanation, stating, “It’s not much more than that.”

Jelena Ostapenko argues with Taylor Townsend after their second round match.
This followed a high-profile spat involving Taylor Townsend and Jelena Ostapenko. After a match earlier in the week, Ostapenko unleashed a furious social media attack, accusing Townsend of having “no class” and “no education” for not apologizing after a net cord winner. Townsend responded to the eventual apology, noting the comments were “hurtful, belligerent, [and] offensive… to a whole culture of people.”
Other notable incidents include:
Daniil Medvedev being fined $42,500 for unsportsmanlike conduct and racket abuse after a first-round loss, following a tirade at the chair umpire.

Players believe the environment plays a key role in the drama. American star Jessica Pegula noted, “New York City tends to bring out just a lot of drama, I guess,” citing the “crazy” and “riled up” crowds.
Defending champion Coco Gauff and Pegula both highlighted the timing: being the final Grand Slam of the season means “tired minds and bodies,” creating a tense, emotional atmosphere where “adrenaline starts flowing.”
