British number one Katie Boulter faced a tough second round at the US Open on September 5, 2026, suffering a swift defeat against Czech seventh seed Karolina Muchova. Boulter managed to win just one game in a 58-minute match, ending with a score of 6-1, 6-0.

Originally set for one of the outer courts, the match was moved to the Louis Armstrong Stadium due to heavy rain, leaving fans disappointed as they witnessed Boulter’s struggle. Reflecting on her performance, Boulter described it as a "bad day at the office" and noted, "I struggled with the conditions. I let things distract me."

Key match statistics include:

• Double faults: 8
• Aces: 0
• First serve points won: 33%
• Unforced errors: 22 compared to 4 winners

In contrast, Muchova showcased her prowess with 14 winners and only 9 unforced errors, demonstrating effective drop shots and powerful groundstrokes.

Fellow Briton Jacob Fearnley also exited the tournament, losing to Argentina's Tomas Martin Etcheverry with a scoreline of 6-3, 6-3, 3-6, 6-3. However, Francesca Jones advanced after winning her first-round match against Magda Linette.

Former world number five Daniela Hantuchova emphasized the need for Boulter to reassess her game, particularly her serve. Despite her tennis struggles this season, Boulter has experienced personal joy after marrying Alex de Minaur, the world number seven, in July. With only two wins in four Grand Slam tournaments this year, Boulter's performance raises concerns as she looks to regain her form.
