Alexander Zverev crossed the line in Mexico and rules around umpire abuse need to be stricter, says Alex Corretja
Eurosport’s Alex Corretja says Alexander Zverev crossed the line after he was disqualified from the Mexican Open for smashing a racquet by the feet of the umpire in his chair. The Tokyo 2020 gold medallist has apologised for his unsportsmanlike conduct on Instagram while former British number one Andy Murray has said his actions were “dangerous” and “reckless”. Ad/> Corretja believes it was good that Zverev was showing his emotions on court, but feels he went too far on Tuesday night.
