Tennis matches finishing at 3am are "unhealthy" for players and should be stopped, says Coco Gauff.
Defending champion Novak Djokovic wrapped up a five-set victory against Lorenzo Musetti at 3:07am on Sunday at the French Open - by far the latest ever finish at the clay-court Grand Slam.
It reopened the discussion around why matches are allowed to continue into the early hours and the impact on player welfare.
"I feel like a lot of times people think you're done, but really at 3am [you're] probably not going to bed until 5am at the earliest, maybe 6am or 7am," said US Open women's champion Gauff.
