Flavio Cobolli did not expect his United Cup singles match to turn into a rules seminar when a loose tennis ball slipped out of his pocket mid-rally and changed the momentum of a tense encounter. Serving for the first set against Stan Wawrinka in Italy’s Group C tie with Switzerland, Cobolli watched a second ball tumble onto the court, paused instinctively, and then lost the point, setting off confusion, frustration, and a lengthy on-court explanation that drew in umpires, supervisors, and both teams.
Flavio Cobolli and Stan Wawrinka Caught in On-Court Confusion After Loose Ball Incident
The incident unfolded with Cobolli serving at 0-15 when a spare ball slipped from his shorts pocket and rolled behind him during the rally. Concerned about his footing, he chose not to strike the next ball and assumed the umpire would call a let.
No call came. Instead, the point was awarded to Wawrinka, prompting Cobolli to walk toward the chair in disbelief. “I cannot hit the ball. I risk to injure my legs. I cannot,” Cobolli said, insisting that playing on would have been dangerous.
The chair umpire pushed back, explaining, “It’s not about looking, because you can’t hinder yourself.” Cobolli continued to argue, saying, “I cannot hit the ball because the other ball was there,” while Italy’s team captain, his father Stefano, joined the discussion from the sidelines.
As the debate dragged on, tour supervisor Gerry Armstrong was called onto the court. Wawrinka, standing nearby, even offered to watch a replay to settle the matter. “Let’s just see the replay. If it come out, we’ll play,” the Swiss star suggested.

Armstrong quickly shut that down, making it clear that video evidence would not change the ruling. “You can’t hinder yourself. Flavio, you can’t hinder yourself. But that’s down to you. It’s nothing to do with Stan,” Armstrong said, emphasizing that the responsibility rested entirely with the server.

Wawrinka then summed it up bluntly for his opponent, saying, “So that’s the rule. That’s not because the ball out, that’s because the rule is, if you drop it, you lose the point.”
How Do the Rules Treat Player-Caused Hindrance During a Rally?
Under ATP regulations, any item dropped by a player other than the racquet during a live point is considered a player-caused hindrance. The point is automatically lost, regardless of intent or perceived danger. Once the explanation was complete, the umpire confirmed the decision, handing Wawrinka a 0-30 lead.
Cobolli regrouped impressively, however, closing out the first set 6-4 and eventually winning a dramatic three-set match 6-4, 6-7(2), 7-6(4). The victory leveled the tie at 1-1 after Switzerland’s Belinda Bencic defeated Jasmine Paolini earlier. The group outcome was left to the deciding doubles match featuring Sara Errani and Andrea Vavassori against Bencic and Jakub Paul.
