Coco Gauff faced a major test at the 2026 U.S. Open on Wednesday, falling behind Mirra Andreeva in a tense women’s quarterfinal at Arthur Ashe Stadium. The American fourth seed dropped the opening set 6-2 in just 26 minutes, but began finding her rhythm during a dramatically more competitive second set.

As of the latest live updates from Flushing Meadows, Andreeva had taken the first set and the second set was level at 5-5. The match remained unsettled, with both players trading breaks and struggling to protect their serves.

Shocking Coco Gauff struggles put quarterfinal in danger

Gauff’s opening set was defined by missed opportunities and unforced errors. Her first-serve percentage fell to 43 percent, compared with 68 percent for Andreeva. The Russian also won 87 percent of points behind her first serve, creating constant pressure whenever Gauff tried to establish a rally.

The American’s forehand proved particularly vulnerable. Gauff committed 10 forehand unforced errors in the first set, while Andreeva made only three. A loose forehand return handed Andreeva set point, and the fifth seed closed it out with a powerful serve down the T.

Gauff’s serve also became a serious concern. By the early stages of the second set, she had committed eight double faults. One of those mistakes gave Andreeva a break point, but Gauff responded with a bold serve-and-volley play, followed by an ace and a passing shot at the net to complete an important hold.

Andreeva’s relentless tactics expose Gauff’s errors

Andreeva entered the match with a clear tactical plan. She repeatedly targeted Gauff’s forehand and used heavy, loopy shots from deep in the court to disrupt the American’s timing. She also mixed in slice defense and redirected rallies toward Gauff’s backhand corner when the opportunity arose.

That strategy worked brilliantly during the opening set. Andreeva’s consistency forced Gauff to attempt lower-percentage shots, while the Russian remained composed during extended exchanges. At one point, Andreeva pinned Gauff into the backhand corner rather than engaging in another forehand-to-forehand rally, drawing an error from the American.

Still, the match began to change in the second set. Gauff’s serves and forehands started landing more regularly, and the long rallies increasingly favored the American. She earned her first break of the match when Andreeva sent a backhand approach long, moving ahead 4-2.

Gauff fights back as Arthur Ashe crowd rallies

The Arthur Ashe Stadium crowd responded to Gauff’s improvement with repeated chants of “Let’s go Coco!” The atmosphere had initially been subdued, with fans offering encouragement as the home favorite struggled through the first set. Her improved movement and more aggressive court positioning gave spectators reason to believe a comeback was possible.

Gauff’s recovery, however, was far from smooth. After breaking Andreeva, she struggled to consolidate the advantage. Several groundstroke errors allowed Andreeva to break back, and the second set soon became a tense exchange of momentum.

Andreeva later faced pressure while serving at 3-5. Two consecutive double faults handed Gauff break points, and a missed volley allowed the American to break back. That swing brought the set to 5-5, although Gauff had earlier missed a chance to take control after spraying six groundstroke errors in one service game.

At another crucial moment, Gauff reached set point but could not convert. Double faults and a forehand into the net gave Andreeva a break point, which the Russian accepted. Andreeva then held to move ahead again, leaving Gauff in a difficult position despite her second-set resurgence.

What comes next for Coco Gauff?

The outcome of the quarterfinal remained unresolved in the latest report, but the match had already highlighted both sides of Gauff’s game. Her speed, defensive ability and fighting spirit kept her competitive, while her serve and forehand errors repeatedly placed her under pressure.

For Andreeva, the performance showed why she is considered one of the rising forces in women’s tennis. Her patience, tactical discipline and ability to redirect rallies helped her control the first set and withstand Gauff’s second-set surge.

The winner will advance to the U.S. Open semifinals. Andreeva is seeking another major breakthrough, while Gauff is attempting to keep her New York campaign alive in front of a fiercely supportive home crowd.
