Defending Open Sud de France champion David Goffin rallied from losing the first set to defeat Benjamin Bonzi in Monday's first-round match.

Eighth seed Goffin, ranked at world number 52, prevailed 2-6 7-5 6-1 in Montpellier against the Frenchman.

It looked bleak for Goffin when Bonzi raced into a 3-0 lead in the second set, yet the Belgian reeled off three successive games to get himself back in the fight before snatching a crucial break to make it 6-5, and he did not look back from there.

"During the match I stayed positive even though I was one set and one break down," Goffin said.

"I tried to stay focussed, to stay as long as possible on the court to try to get some confidence, to work on certain things: to be more aggressive, [hit] a better quality of ball.

"At the end it was better and better, so I'm really happy the way I played at the end of the second and in the third."

Next up for Goffin is a tie with Spain's Alejandro Davidovich Fokina, or another Frenchman in the form of Adrian Mannarino, who lost to eventual Australian Open winner Rafael Nadal in Melbourne last month.

Monday's other match saw sixth seed Alexander Bublik defeat Tallon Griekspoor 7-6 (7-4) 7-6 (7-5).

Yuki Bhambri was the story at the Tata Open Maharashtra, as the Indian claimed a first tour-level match win in almost four years, beating Jozef Kovalik 6-7 (10-12) 6-2 7-5.

Bhambri, ranked at 863 in the world, had only played two singles matches on the ATP Tour since 2019 due to a knee injury and had last beat Mirza Basic in Miami in 2018.

"It is a privilege to play at home and it is an important win as well playing at my home tournament," he said. "Each match is tough at tour-level so I am just taking it one match at a time."

Radu Albot beat Federico Gaio in straight sets, while seventh seed Ricardas Berankis was shocked by Quentin Halys and Daniel Altmaier also progressed.
