Jessica Pegula Stuns Noskova in Three-Set Thriller, Ends Coco Gauff's WTA Finals Campaign

Jessica Pegula produced a remarkable comeback, saving a match point before overcoming Linda Noskova in a three-set thriller to book her place in the semifinals of the WTA Finals and eliminate Coco Gauff from the season-ending tournament.

The American, who fired a career-high 16 aces, prevailed 7-6(2), 4-6, 7-5 in a gripping Group 1 encounter in Indian Wells on Thursday. She will now face Mirra Andreeva in the semifinals.

Pegula found herself on the brink of defeat when Noskova led 5-4 in the deciding set and earned a match point on the American's serve. However, the 31-year-old held her nerve, producing an ace to level the set at 5-5.

She then broke Noskova's serve in the following game before sealing victory on her first match point, with a net cord falling in her favour.

Pegula's victory proved decisive in the group standings. Both Pegula and Noskova finished with two wins from three matches, but the American's progression came at the expense of Coco Gauff, her former doubles partner.

Earlier, Gauff ended her campaign with a 6-4, 7-5 victory over Ukraine's Marta Kostyuk, recovering from a difficult position in the second set.

Gauff trailed 1-5 in the second set after struggling with her serve and receiving treatment for back stiffness. Kostyuk was also dealing with a wrist problem that affected her ability to serve.

The American fought back brilliantly, winning six consecutive games to complete the straight-set victory. However, the result was not enough to keep her semifinal hopes alive after Pegula defeated Noskova.

Kostyuk, who entered the tournament as the first alternate following Elena Rybakina's withdrawal due to a viral illness, finished her campaign without a win.

In the doubles competition, Katerina Siniakova and Taylor Townsend advanced to the semifinals after their opponents, Nicole Melichar-Martinez and Cristina Bucsa, retired due to a knee injury sustained by Melichar-Martinez.
