Linda Noskova beats Coco Gauff to secure WTA Finals semi-final spot

Linda Noskova became the first player to secure a semi-final place at the WTA Finals with a 6-3, 6-3 victory over Coco Gauff, according to BBC Sport. The Wimbledon champion advanced on her debut at the season-ending tournament, while Gauff remained in contention for a place in the last four despite the straight-sets defeat.

The 21-year-old Czech, ranked eighth in the world, combined forceful hitting with an assured serving performance. BBC Sport reported that she broke Gauff four times in the opening set, putting pressure on the American's service games throughout. Noskova continued to dictate play in the second set, making just one unforced error before ending the match with an ace.

The result gave Noskova her sixth victory over a top-10 opponent this season. It added another milestone to a campaign in which she won the Berlin Open before claiming her first Grand Slam title at Wimbledon in July. Her first appearance at the WTA Finals has now brought a place in the knockout stage.

Gauff's serving figures underlined her difficulties. The world number four recorded eight aces but also eight double faults, and won only six of the 24 points played behind her second serve. She had opened her tournament by beating fellow American Jessica Pegula on Sunday, but could not follow that win with another against Noskova.

Pegula, meanwhile, kept her own qualification hopes alive by beating alternate Marta Kostyuk 6-2, 7-5 in the other group-one match. BBC Sport described it as Pegula's first victory since September. The result eliminated Kostyuk, who had also lost to Noskova in her opening match on Sunday.

Kostyuk had been managing a wrist injury since August and learned only on Saturday that she would enter the tournament following world number one Elena Rybakina's withdrawal. Against Pegula, the Ukrainian made 17 unforced errors in the first set, compared with five from her opponent, before a more closely contested second set.

Pegula moved a break ahead in that second set, but further exchanges of service breaks delayed the finish. She eventually broke at 5-5 and served out the victory. With Noskova through and Kostyuk eliminated, both Pegula and Gauff still had a route to the semi-finals.
