The Instagram story was written on a rainbow background.
Medvedev nearly fainted during the match and Fognini also struggled with the heat.
Fognini repeatedly slammed his racket during the loss, including after the final point, upon which he picked the racket up and deposited it in a court-side trash can.
The volatile Fognini was kicked out of the doubles tournament at the U.S. Open in 2017 for vulgarly insulting the chair umpire during his first-round loss in singles. He was then handed a suspended ban of two Grand Slam tournaments.
