US Open 2025: Leandro Riedi says abuse from bettors 'needs to stop'

In the small confines of the US Open outside courts, it is virtually impossible for players not to hear exactly what fans are saying, even when they are focusing on a potentially career-defining match.

Shouts from courtside are almost universally supportive - but some players are starting to believe all is not what it seems.

In a peculiar New York incident, Switzerland's Leandro Riedi reported a vocal fan to the chair umpire - for cheering him on.

Exasperated by losing a break, 23-year-old Riedi suspected the man was a bettor and decided to act.

"It feels like more and more bettors are coming to watch," said Riedi, who has reached the last 16 in only his second Grand Slam main draw.

"Of course they can come to watch tennis if they stay on the right side of the line, but I think it is a problem which is getting bigger and bigger because of social media.

"If people come live [to matches] and support that's nice, of course.

"But you know if you lose, one of these guys who are betting might abuse you on social media later."
