Serena Williams said she would have faced far harsher punishment had she engaged in similar behavior to Zverev
After shaking hands with the opponents, the 24-year-old Zverev, ranked third in singles, approached the umpire's chair and hit it repeatedly before heading towards his courtside seat, upset over a line call during the match earlier.
Zverev deserved to be thrown out for umpire abuse, says Nadal
Alexander Zverev received a suspended eight-week ban for smashing his racket against the umpire's chair at last month's ATP 500 event in Acapulco, for which he was expelled from the tournament.
