Novak Djokovic launched his quest for a record-breaking 23rd men's Grand Slam singles title with a no-nonsense 6-3 6-2 7-6 (1) win over debutant Aleksandar Kovacevic in the opening round of the French Open on Monday.
World number one Carlos Alcaraz also came through with flying colours as the Spaniard crushed Italian qualifier Flavio Cobolli 6-0 6-2 7-5 in his first Grand Slam match since winning the US Open title last year.
Twice Roland Garros champion Djokovic breezed through the first two sets before encountering resistance from the 24-year-old American whose lack of experience then showed in the tiebreak on the world's biggest clay court.
Djokovic ended the contest with a sizzling service return on his first match point and will face Hungarian journeyman Marton Fucsovics for a place in the third round.
"It's always a pleasure to come back here, one of the best tournaments in the world," said Djokovic, who made his Roland Garros debut in 2005.
"I'm very motivated to go far here, all the way I hope."
Djokovic did not have an ideal build-up to the claycourt Grand Slam, missing the Madrid Masters and being eliminated in the last eight in Rome, but he looked in good form in windy conditions.
On court Suzanne Lenglen, Benoit Paire was beaten in five sets by British 14th seed Cameron Norrie. Paire, given a wildcard, was up a break in the decider but could not close out the match.
"I'm happy with all the efforts that I've been making for some time. So today it was a great match," said world number 149 Paire, who has not won in the main draw in a top tier event since August.
Dominic Thiem took his main draw spot after the withdrawal of 14-times champion Rafa Nadal - his conqueror in the 2018 and 2019 finals but the injury-plagued Austrian fell to Argentine Pedro Cachin who won 6-3 6-2 6-7(1) 4-6 6-2.
Italian veteran Fabio Fognini showed he was still a force to be reckoned with as he dismissed ailing 10th seed Felix Auger-Aliassime 6-4 6-4 6-3, making the Canadian the first top-10 player in the men's draw to crash out.
