It is certainly not the first instance where the Tsitsipas team have caused a stir with their in-game tactics and conversations.
Back in January, Daniil Medvedev accused Tsitsipas’ father of coaching him from his box — ironically in Greek on that occasion. The Russian’s complaint was heard by the chair umpire Eva Asderaki-Moore, who opted to sit underneath the 24-year-old’s box so she could listen to their exchanges.
The 2019 ATP Finals winner Tsitsipas was then forced to deny claims that he had parted ways with his father after bringing in former pro Thomas Enqvist to join his coaching team, amid calls for him to consider separating from his mentor, who has guided him for the entirety of his career.
He will face American veteran John Isner, who is unseeded for the tournament, in the last eight. Schwartzman, meanwhile, will continue his preparations for the US Open after his exit, with the final Grand Slam of the year getting underway on August 29.
