Frenchman Richard Gasquet (38) saved a match point and rallied past Brazil’s Thiago Monteiro 4-6, 6-4, 7-6 to kick off his final appearance at the Moselle Open on Monday in Metz, France.

Gasquet, 38, announced he will retire after the French Open next summer. Back in 2004 Metz was the site of his first of 33 ATP Tour finals appearances.

The former World number seven had 14 aces and won 49 of 55 first-serve points (89.1 per cent) against Monteiro; he saved match point to tie the third-set tiebreaker 6-6 and won the next two points to finish the job.

Seventh-seeded Jan-Lennard Struff of Germany charged past Kazakhstan’s Alexander Shevchenko 3-6, 6-4, 6-4. Great Britain’s Cameron Norrie, French qualifier Quentin Halys and Italian Lorenzo Sonego also advanced out of the first round.
