Six-times champion Novak Djokovic emerged from the Rod Laver Arena furnace and into the third round of the Australian Open after putting suffering Gael Monfils out of his misery with a scrappy victory on Thursday.
After winning the first set, Monfils deteriorated in the heat and went on to lose to the former world number one 4-6 6-3 6-1 6-3. "I'm still not 100 percent, but building".
"It was brutal", Djokovic, who again played with a compression sleeve and employed a truncated service action, said on court.
Konta saved three match points in the ninth game of the second set, then broke Pera to level the set at 5-all. During the first set, Djokovic struggled while serving, as he committed five double faults, nearly half of a total of his 11 double faults during the match. In the victory, Ramos-Vinolas won 92 percent of his first serve points and 62 percent of his second serve points.
The six-time champion looked like a man who had been sidelined for six months during the first set, making uncharacteristic errors at bad times and finding his remodelled serve given a pounding.
Djokovic needed four match points in the final game which stretched over eight minutes.
The victor will face either Tim Smyczek or Albert Ramos-Vinolas in the third round.
American Sam Querrey is out of the Australian Open after losing his second-round match 6-4, 7-6 (6), 4-6, 6-2 to 80th-ranked Marton Fucsovics of Hungary.
The 17th-seeded Keys was dominant serving in the first set. The unseeded Indian combination did not face too much trouble from their European opponents as they eased to a 6-2, 6-3 win. Meanwhile, the 10th seeded duo of Bopanna and French star Édouard Roger-Vasselin got the better of Vasek Pospisil of Canada and American Ryan Harrison by a 6-2, 7-6 margin. Djokovic has won seven of his last nine matches on hard court. Nor did Wimbledon champion Garbine Muguruza, one of the five seeded women's players who were eliminated on Day 4.
Juan Martin del Potro, the 2009 US Open victor, overcame a medical timeout for a left leg injury to oust Karen Khachanov 6-4 7-6 (7-4) 6-7 (0-7) 6-4.
RON REED has spent more than 50 years as a sportswriter or sports editor, mainly at The Herald and Herald Sun. The Germany said that the heat and the resulting fatigue had drained her mentally after her loss to United States' Lauren Davis following a marathon first match and a doubles.
"I feel more for the spectators". They are so strong.
"I think the surface of the court, I don't know how much heat, it's awful, very, very hot, and it's easy to get blisters and red", she said after losing to 88-ranked Hsieh Su-wei from Taiwan. The 19th seeded Berdych took two hours and 31 minutes to overcome World No.71 Garcia-Lopez.
It was the Latvian who ended her Grand Slam comeback in the last 16 of the US Open in 2017 as she returned from a drug ban.
"I think there are certain days where you just have to, as a tournament supervisor, recognise that you might need to give players few extra hours until it comes down".
"I didn't expect to play this kind of match", a thoroughly exhausted Juan Martin del Potro said after beating Karen Khachanov in a almost four-hour, second-round match.
