Alexander Zverev has denied using his phone during his match against Stefanos Tsitsipas at the ATP Finals.
Zverev was asked about the incident at a news conference after he was seen touching something in his bag at a changeoverduring Wednesday’s defeat.
The 22 – year-old German, who lost 6-3 6-2 at London’s O2 Arena, said: “I don’t know what they saw, but it was definitely not a phone. “
Rules state players cannot access any electronic devices during matches.
” My phone was in the locker room. I always leave it there, “added Zverev.
Asked what he might have been touching, he said:” I mean, a water bottle? Empty water bottle maybe? “
