Novak Djokovic eased through to the second round of the French Open after a straight-sets win over Rogerio Dutra Silva.
The Serbian, coming back from an injury absence which has seen him dip out of the world’s top 20 for the first time since he was a teenager, dropped his serve in the opening game of the match.
But it proved a false alarm as the 12-time grand slam winner brushed aside his Brazilian opponent 6-3 6-4 6-4.
While a routine victory over the world number 134 may not be proof that Djokovic is ready to mount a sustained challenge to Rafael Nadal for the Roland Garros crown, it was at least an encouraging start for the 2016 champion.
Another former Paris winner, Stan Wawrinka, bowed out after a three-and-a-half hour marathon against Guillermo Garcia-Lopez.
The Swiss star, beset by knee problems for two years and seeded a lowly 23, needed lengthy treatment during the first set and appeared unlikely to be able to play on.
But not only did Wawrinka continue, he went on to take a 2-1 lead only to lose an epic five-setter 2-6 6-3 4-6 7-6 (7/5) 6-3.
Argentinian Marco Trungelliti had embarked on a nine-hour drive from Barcelona to Paris on Sunday – and it proved well worth it.
The 28-year-old was back home in Spain when, after a spate of first-round withdrawals, he got the call to replace the injured Nick Kyrgios.
He arrived in Paris just before midnight, registered on Monday morning and walked out on court nine to face Australian former world number 17 Bernard Tomic.
And Trungelliti, who had earned £26,250 so far this year, will now pocket at least double that after battling to a surprise 6-4 5-7 6-4 6-4 victory.
