On a humid day when play was halted for three hours on most courts, Andy Murray turned back the clock to overcome 13th seed Matteo Berrettini at the Australian Open on Tuesday.
On day two, however, there was controversy off the court since Russian and Belarusian flags were forbidden at Melbourne Park.
Following his suspension and expulsion last year, Novak Djokovic is scheduled to play in the Grand Slam later on Tuesday.
However, the 35-year-old Murray seemed to had the day in the bag as the British player survived match point to upset Italy's Berrettini 6-3, 6-3, 4-6, 6-7 (7/9), 7-6 (10/6) in 4 hours and 49 minutes on Rod Laver Arena with the roof closed owing to the high heat.
“I will be feeling this this evening and tomorrow,” the former world number one, who plays with a metal hip after career-saving surgery, said.
“But right now unbelievably happy and proud of myself.
“I’ve put a lot of work into the last few months with my team to give me this opportunity to perform in stadiums like this, in matches like this and against players like Matteo — and it paid off tonight.”
“I did well to get through,” added the three-time major winner, who faces either Fabio Fognini or Thanasi Kokkinakis in round two.
In the men's draw, Andrey Rublev, ranked fifth, defeated Dominic Thiem, the event finalist for 2020, 6-3, 6-4, 6-2 in temperatures of 36 degrees Celsius (96.8 degrees Fahrenheit).
As he started his comeback from a wrist injury that kept him off the court for nine months over the 2021 and 2022 seasons, former US Open champion Thiem was outplayed.
On outdoor courts, play had to be stopped as the temperature climbed. The three major stadiums—Rod Laver Arena, Margaret Court Arena, and John Cain Arena—had their roofs shut.
About three hours later, play began on the outside courts once again.
The men's seeds, like those in the women's draw, were mostly unaffected.
Dan Evans of the United Kingdom, Pablo Carreno Busta of Spain, Grigor Dimitrov of Bulgaria, and Diego Schwartzman of Argentina all advanced to round two.
Nikoloz Basilashvili of Georgia was beaten by eighth-seeded Taylor Fritz of the United States 6-4, 6-2, 4-6, 7-5.
Due to his views on Covid vaccinations, Serbia's Djokovic was deported on the eve of the Australian Open in 2017.
However, the 35-year-old will be in action when he takes on Spanish opponent Roberto Carballes Baena in his first round and is expected to get a rousing ovation from the Rod Laver Arena fans.
In order to equal current winner Rafael Nadal's record of 22 Grand Slam victories for men, he must win the Australian Open for a record-extending 10th time.
