WORLD number two Daniil Medvedev reached the French Open second round with a comfortable win but 14th seed Denis Shapovalov made a surprise exit.
US Open champion Medvedev, 26, won 6-2 6-2 6-2 against Argentine Facundo Bagnis, ranked 103rd.
The Russian reached his first quarter-final at Roland Garros last year – having lost in the first round the four previous times.
He had been unsure of his participation after a hernia operation in April.
“I love Roland Garros, especially since last year. I hope this year I can go further,” said Medvedev, who will meet Serb Laslo Djere next.
“When I went under the operation I didn’t think I was going to play on clay, but I managed with the doctor and physio to get back. Physically, I feel 100 per cent.”
Meanwhile, 2021 Wimbledon semi-finalist Shapovalov said he “didn’t really show up” in a straight-sets defeat by Danish 19-year-old Holger Rune.
The 23-year-old Canadian, who reached the last eight at the Australian Open earlier this year, made a huge 53 unforced errors as the 2019 junior Roland Garros champion won 6-3 6-1 7-6 (7-4).
Australia’s Alex de Minaur, seeded 19th, also suffered an early exit following a final-set tie-break against French 21-year-old Hugo Gaston, who prevailed 4-6 6-2 6-3 0-6 7-6 (10-4).
Russian seventh seed Andrey Rublev had to come from a set down to defeat South Korean Kwon Soon-woo 6-7 (5-7) 6-3 6-2 6-4.
Norwegian eighth seed Casper Ruud also progressed, as his 6-7 (6-8) 7-6 (7-4) 6-2 7-6 (7-0) win over Jo-Wilfried Tsonga brought an end to the Frenchman’s career.
Elsewhere, Frenchman Benoit Paire served 24 double faults in a 6-3 7-5 1-6 7-5 loss to Ilya Ivashka.
Paire had lost in the first round in 10 consecutive tournaments before picking up a victory at last week’s Geneva Open – his only win on the ATP tour this year. (BBC Sport)
