World number two Daniil Medvedev reached the French Open second round with a comfortable win but 14th seed Denis Shapovalov made a surprise exit.

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 or Lithuanian Ricardas Berankis 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).

Bagnis hampered by injury in Medvedev defeat

Bagnis, 32, immediately responded after seeing his serve broken in the opening game - but that was to prove a rare glimmer of hope for him against Medvedev on Court Suzanne Lenglen.

In a dominant display, second seed Medvedev won nine successive games as he efficiently settled the first set and took a commanding 4-0 lead on his way to clinching the second.

The Russian, unable to compete under his national flag because of the war in Ukraine, saw his progress checked as Bagnis - struggling with a calf issue throughout - broke back to level the third set at 2-2.

But that only served to refocus Medvedev, who rattled through the next four games to end the contest after just one hour and 38 minutes.

Bagnis could be fined his full prize money if it is decided that his injury prevented the Argentine meeting the required professional standard.

"It was a tough first round. I tried to give my best. I didn't have it in my best condition, I had a problem last week in my leg, but I came here to Roland Garros to get ready and try to give 100 percent," Bagnis said.

"But today after the warm-up I felt it again, the problem, so it was tough because I think I couldn't play, but I wanted to continue. I wanted to finish the match, so, I tried to do it, but it was not to easy so that's the reality."
