Andy Murray says Alexander Zverev’s extraordinary moment of rage at the Mexican Open was “reckless” and “dangerous” — after an attack on the umpire’s chair resulted in him being thrown out of the tournament. The German, teaming up with Brazil’s Marcelo Melo, seemed to react fairly cordially at the net when they were defeated by Britain’s Lloyd Glasspool and Finland’s Harri Heliovaara, but after the handshake he shouted expletives towards chair umpire Alessandro Germani and then furiously battered his chair, narrowly missing the official’s feet. Ad/> Zverev has since apologised publicly and to the umpire, saying he rejects his actions and that he “left too much” out on the court.
