Marta Kostyuk vs. Coco Gauff — Indian Wells WTA Finals 2026 Group 1 Round-Robin Match Report.
Marta Kostyuk was three points away from winning the second set. Three separate times, she needed just one more point to force Coco Gauff into a decider.
She failed every time.
What followed was a remarkable collapse, as the Ukrainian surrendered six consecutive games to hand Gauff a 6-4, 7-5 victory on Thursday, November 12, at the WTA Finals in Indian Wells.
Kostyuk had led 5-1 in the second set. By the time she walked off court, she had lost her third consecutive match at the tournament.
For Gauff, the escape kept her semifinal hopes alive. But it was ultimately in vain, as Linda Noskova failed to defeat Jessica Pegula, ending the American’s WTA Finals campaign.

Kostyuk’s second-serve statistics were almost identical, with the Ukrainian winning only 32% of those points.
Gauff nevertheless held a decisive advantage behind her first serve, winning 70% of those points compared with Kostyuk’s 57%.
She also converted six of ten break opportunities, while Kostyuk managed four of eight.
The American finished with 78 of the match’s 145 points, eleven more than her opponent.
The difference was not spectacular tennis. It was Gauff’s ability to survive the moments when defeat in the second set appeared imminent.
Gauff’s Great Escape Ends in WTA Finals Elimination
Coco Gauff’s remarkable comeback against Marta Kostyuk ultimately proved insufficient to keep her WTA Finals campaign alive.
The American finished the round-robin stage with two victories and one defeat, having beaten Jessica Pegula and Kostyuk but lost to Linda Noskova in straight sets.
Her semifinal hopes depended on Noskova defeating Pegula in the final Group 1 match. However, Pegula emerged victorious, eliminating Gauff on the percentage of sets won in the resulting three-way tie.
For Kostyuk, the tournament ended without a single victory in three matches.
Gauff, meanwhile, will have mixed feelings about her final appearance in Indian Wells.
Her tennis was far from convincing for much of Thursday’s encounter, yet she showed tremendous resilience to recover from 5-1 down and a lower back issue early in the second set and save three set points.
Unfortunately for the American, that fighting spirit could only take her so far.
Gauff saved three set points to keep her straight-sets victory over Kostyuk intact, only to see her WTA Finals hopes disappear three hours later when Jessica Pegula defeated Linda Noskova.
