Denis Istomin upsets Richard Gasquet at Moselle Open

METZ, France -- Sixth-seeded Richard Gasquet lost 1-6, 6-4, 6-4 to Denis Istomin in the first round of the Moselle Open on Tuesday, while top-seeded Pablo Carreno Busta withdrew from the tournament with an injury to his left hand.

Organizers said Busta, who is ranked 10th in the world and made it to the semifinals at the US Open, was due to play his opening match in Metz on Thursday. He was replaced in the draw by Frenchman Kenny De Schepper.

Gasquet, who struggled with injuries recently but won a tournament on the Challenger tour last week in Poland, made a strong start and seal the first set after dropping only four points on his serve. But the Frenchman then failed to convert any of seven break points and dropped his serve twice.

Istomin will be up against lucky loser Yannick Maden in the next round.

No. 7 seed Benoit Paire advanced to the second round by defeating qualifier Stefanos Tsitsipas 6-2, 6-4.
