MELBOURNE, Australia — Facing a break point late in the third set, Rafael Nadal sprinted to his left and hit a running, around-the-post forehand that landed just inside the line.
The lingering back soreness that bothered the 20-time major champion ahead of the Australian Open wasn't going to stop him from finishing his first-round match as quickly as he could.
Laslo Djere, ranked 56th, shrugged, his head dropped and he no doubt wondered what more he needed to do to win a point.
He'd had three break points when Nadal was serving for the second set, and didn't get close to cashing in one.
When Djere, going for everything, double-faulted to open what became the last game of the match, a woman in the crowd at Rod Laver Arena yelled out "It's all right, Laslo."
Easy for her to say.
Nadal finished off a 6-3, 6-4, 6-1 win in just under two hours in his first competitive match in months — he didn't play for Spain at the ATP Cup last week because of the back stiffness.
"My back is not perfect, as I said a couple of days ago," Nadal said. "Every day that I'm able to go through, probably there are more chances to get better. That's the thing now — there is always a chance to improve, and that's why I'm here playing and fighting to try to get better and then give myself a chance."
A slight change to his service motion was among the precautions he took "survive" for the first round.
"I need to go day-to-day," he said, "and just try to stay positive."
He'll next play American qualifier Michael Mmoh, who outlasted Viktor Troicki 7-6 (3), 6-7 (3), 3-6, 7-6 (3), 7-5.
While Nadal has been slowly building into the tournament, Russia's ATP Cup-winning teammates have been on a roll.
Fourth-seeded Daniil Medvedev extended his winning streak to 15 matches with a 6-2, 6-2, 6-4 win over Vasek Pospisil and seventh-seeded Andrey Rublev beat Yannick Hanfmann 6-3, 6-3, 6-4.
While Sofia Kenin struggled with nerves in her first match as a defending champion at a Grand Slam tournament before beating 133rd-ranked wild-card entry Maddison Inglis 7-5, 6-4, top-ranked Ash Barty dominated in her first Grand Slam match in more than a year, dropping only 10 points in a 6-0, 6-0 rout of Danka Kovinic.
Barty lost to Kenin in the semifinals last year and then skipped the U.S. Open and her title defense at the French Open because she stayed in Australia during the COVID-19 pandemic.
After her 44-minute opener on Rod Laver Arena, Barty said she'd missed tennis "every single day" during her time away from the sport.
"The competitor in me missed what this is all about," she said. "Coming out here and really enjoying the thrill of the fight."
Garbiñe Muguruza, the Australian Open runner-up last year, defeated Margarita Gasparyan 6-4, 6-0.
Players who were forced into hard lockdown after landing in Australia last month have struggled in the opening round.
Victoria Azarenka, a two-time Australian Open champion and the runner-up at last year's U.S. Open, appeared to have trouble breathing and received medical attention in the second set of a 7-5, 6-4 loss to Jessica Pegula of the United States.
Azarenka noted how difficult it was to prepare for a major tournament after being one of 72 players who were in a hard quarantine for two weeks — not allowed to leave their hotel rooms for any reason — after potentially being exposed to COVID-19 on her flight to Australia.
"The biggest impact for me personally has been not being able to have fresh air," the 12th-seeded Azarenka said. "That really took a toll."
Sloane Stephens lost to No. 26-seeded Yulia Putintseva 4-6, 6-2, 6-3 and Paula Badosa, who went through a three-week isolation because she tested positive for COVID-19, served for the match but dropped the last four games and was beaten by Liudmila Samsonova 6-7 (4), 7-6 (4), 7-5.
Two-time Australian Open quarterfinalist Tennys Sandgren also went through the hard lockdown. After losing to No. 21 Alex de Minaur 7-5, 6-1, 6-1, Sandgren said for those who'd been through it, the tournament is "not feasible."
"I've never walked on to a court in a Grand Slam knowing that I'm probably not going to be able to win," he said.
In other results on a sunny Day 2 with the temperature in the low 70s Fahrenheit (low 20s Celsius), Australian wild-card entry Alexei Popyrin saved four match points to beat No. 13 David Goffin 3-6, 6-4, 6-7 (4), 7-6 (6), 6-3 and 17-year-old Spaniard Carlos Alcaraz defeated Botic Van de Zandschulp 6-1, 6-4, 6-4 to become the youngest man to win a Grand Slam match since Thanasi Kokkinakis in 2014.
And an even younger player, 16-year-old Coco Gauff, won 6-3, 6-2 against Jil Teichmann to set up a second-round showdown against fifth-seeded Elina Svitolina.
Other seeded players advancing included No. 6 Karolina Pliskova, No. 21 Anett Kontaveit and No. 25 Karolina Muchova.
Mayar Sherif made history for Egyptian tennis, beating fellow qualifier Chloe Paquet 7-5, 7-5 to become the first woman from her country to win a Grand Slam match.
"Obviously, it means a lot," Sherif said, "because finally this is barrier that I had to pass, a mental barrier."
