Alexander Zverev has defended himself after his second group match at the ATP Finals in London against emerging cheating allegations. A TV camera had caught on Wednesday evening in his 3: 6, 2: 6 defeat against the Greek Stefanos Tsitsipas, as the 22-year-old had squeezed several seconds with his hand in his sports bag during a break.
A discussion had then developed on social networks as to whether Zverev might have used a cell phone. Mobile phones and communications of any kind are prohibited during matches because they offer the possibility for illegal coaching. "My phone was in the locker room," Zverev said, "I'm not sure what they saw, but it could not have been my phone, maybe a water bottle."
Zverev had missed by his defeat against Tsitsipas the premature entry into the semi-finals of the elite tournament of the eight season best. In his last preliminary round game, however, he has on Friday against the Russian Daniil Medvedev the chance to reach the knockout round with a win. If Tsitsipas wins against Rafael Nadal in the other match of the group "Andre Agassi", he will even have to win a set.
