Second-seeded Daniil Medvedev defeated Argentine Facundo Bagnis in straight sets Tuesday to easily advance to the second round of the French Open at Roland Garros in Paris.

Medvedev blasted 12 aces in winning 6-2, 6-2, 6-2 in an efficient one hour, 38 minutes. Medvedev showed no signs of rust after missing most of the European events to recover from hernia surgery. He broke Magnis' serve eight times.

Medvedev will face Serbia's Laslo Djere in the second round. Djere defeated Lithuania's Ricardas Berankis 6-4, 6-4, 6-4 in two hours, three minutes.

No. 14 seed Denis Shapovalov of Canada fell to Holger Rune of Denmark in straight sets, 6-3, 6-1, 7-6 (4).

"It was difficult. For sure I wasn't able to bring out my best performance. It's definitely frustrating," Shapovalov said. "It just shows I have a lot to work on. And just excited to get back to work. Never think I'm done learning and improving."

Seventh-seeded Andrey Rublev of Russia rallied from a set down to defeat South Korea's Soonwoo Kwon 6-7 (5), 6-3, 6-2, 6-4 in two hours, 56 minutes to advance. Rublev hit 15 aces and won 78 percent of his points on first serve.

In other matches, Richard Gasquet of France advanced but his countrymen Ugo Humbert, Benoit Paire and Arthur Rinderknech all fell.

So did France's Jo-Wilfried Tsonga, who ended his career with a four-set loss to eighth-seeded Casper Ruud of Norway. Tsonga, who once reached No. 5 in the rankings during his 18-year career, said earlier the French Open would be his last tournament before retiring.

Sebastian Korda defeated Australian John Millman to advance but fellow American and No. 30 Tommy Paul lost to Chile's Cristian Garin in four sets.

David Goffin of Belgium, Henri Laaksonen of Switzerland and No. 32 Lorenzo Sonego of Italy also posted victories.
