World number one Novak Djokovic completed a solid 6-2 6-3 7-6(4) victory over Slovakia's Alex Molcan in the second round of the French Open to keep his title defence and quest for a record-equalling 21st Grand Slam on track.
With Djokovic unable to defend his Australian Open title due to his refusal to be vaccinated against COVID-19, Spaniard Rafa Nadal broke a three-way tie for the most Grand Slam titles with the Serb and Roger Federer by winning the Melbourne Park major at the start of the year.
Yet a successful rerun of his 2021 Roland Garros campaign, when he beat 13-time French Open winner Nadal in the semi-finals, will lift Djokovic alongside his great rival.
On a blustery day on Court Suzanne Lenglen, the 35-year-old Djokovic cruised through the opening two sets, breaking Molcan's serve three times without giving the Slovakian a single opportunity on his own delivery.
With nothing to lose, Molcan opened up his shoulders in the third set and with some aggressive all-court hitting managed to cancel out Djokovic's early advantage to force a tiebreak.
The top seed will next meet Slovenia's former world number 43 Aljaz Bedene for a place in the fourth round.
Alexander Zverev overcame a woeful start to reach the third round, saving a match point in a 2-6 4-6 6-1 6-2 7-5 victory over up-and-coming Argentine Sebastian Baez.
The German third seed survived a late fightback from the world number 36 and screamed his lungs out when Baez sent a forehand wide on match point.
It was the fifth year in a row that Zverev, who achieved his best result at Roland Garros when he reached the semi-finals last year, had to go through a five-setter in one of the opening two rounds.
Another obstacle in women's top seed Iga Swiatek's path to a second French Open title was removed as fourth seed Maria Sakkari was knocked out 7-6(5) 7-6(4) by Czech Karolina Muchova in the second round.
Sakkari, a semi-finalist in Paris last year, never found her groove on Court Suzanne Lenglen as her opponent, who reached the Australian Open semi-finals last year, set up a meeting with American Amanda Anisimova.
The Greek was the latest high seed to exit after Tunisia's Ons Jabeur (6) and defending champion Barbora Krejcikova (2) were knocked out in the first round.
World number one and red hot favourite Swiatek and third seed Paula Badosa are the only two players from the top six left in the women's draw.
U.S. Open champion Emma Raducanu was bundled out losing 3-6 6-1 6-1 to inspired Belarusian Aliaksandra Sasnovich.
