However, as the crowd rose to applaud for Tsitsipas and instead of rushing towards the net to celebrate, the Greek fourth seed headed to the back of the field as if expecting another service match.
The referee’s announcement of his victory sparked the realization that he had won and he quickly turned around, with surprise on his face, to make his way to the net to shake Pierre’s hand and then begin the proper celebration of his victory.
Tsitsipas, a two-time semi-finalist in Melbourne, complemented Bayer after their tough encounter.
“It was a very important victory for me today and also very special to play on this arena and share that with the fans.”
Tsitsipas will play Taylor Fritz in the next round after the American beat Roberto Bautista Agut in five sets on Saturday.
The 2021 finalist took an hour and 55 minutes to beat the Dutchman 6-4, 6-4, 6-2.
Medvedev, the US Open champion, will play American Maxime Crissy in the round of 16.
The 25-year-old Russian is the highest-ranked player in the lottery and looked fantastic during the opening stages of the tournament.
“(At) a Grand Slam, every round is very difficult and even today if the result doesn’t show that, I feel it was a stronger match than the result.”
