SHANGHAI - Alexander Zverev weighed in on the debate about players' use of towels Friday, saying those who wipe down after every point are "ridiculous" and do it for superstition, not sweat. There has been much discussion at the Shanghai Masters about the issue after Fernando Verdasco berated a ball boy for failing to bring his towel fast enough. Roger Federer told reporters in Shanghai earlier this week that ball boys and girls -- who are unpaid volunteers -- should be given as much respect as anyone else. "There are some players -- some American players, some other players -- that go for the towel literally after every single point," said the 21-year-old German prodigy Zverev. "That's a bit ridiculous, in my perspective. I mean, some players literally use it as superstition." AFP
