Coco Gauff survives quarter-final scare despite serving struggles
Coco Gauff barely escaped an early exit at the US Open, overcoming Mirra Andreeva in a tense quarter-final battle. The Russian held two match points, but Gauff managed to turn the encounter around, eventually prevailing 2-6, 7-6, 6-2 to secure her spot in the semi-finals in New York.
Despite the victory, the performance was far from seamless. The American was plagued by serious delivery troubles throughout the match, producing 12 double faults and claiming just 38 percent of points behind her second serve. While she relied on four aces to generate 22 winners overall, she also committed 42 unforced errors—matching Andreeva’s mistake count across the three sets.

| 1st Serve % | 59% | 67% |
| Win % on 1st Serve | 72% | 62% |

Pre-tournament optimism challenged by mounting double faults
Prior to the tournament, Gauff expressed strong belief that her technical adjustments were bearing fruit. Speaking in her pre-tournament press conference, she explained the timing behind her overhaul.
“I made a big change just before probably the most important tournament of my season [in 2025], and there was a lot of pressure, but I’m really glad I made the decision,” Gauff reflected on the adjustment. “I’m glad I didn’t wait another second, because the progress is there and I see it.”
That initial progress appeared real through the opening four rounds, where she averaged only four double faults per match. However, under the high stakes of the quarter-finals, her service motion wavered significantly. The 12 double faults represented her joint second-highest single-match total of the 2026 WTA Tour season.
