Katie Boulter experienced a disheartening defeat at the US Open after her match against Karolina Muchova was moved to the Louis Armstrong Stadium due to heavy rain. The British number one faced a nightmare scenario, suffering a 6-1, 6-0 loss in under an hour, marking her worst defeat at a grand slam.

Boulter initially showed promise, breaking Muchova’s serve in the first game and creating opportunities for another break. However, Muchova, who was the runner-up at this year’s Wimbledon, quickly took control, leaving Boulter unable to win another game. The statistics highlighted her struggles:

• Seven service games lost
• 21 unforced errors
• Only four winners

In contrast, Britain’s Jan Choinski reached day four at the US Open, despite being a first-round casualty. The towering 30-year-old was eliminated by Dutchman Botic van de Zandschulp in straight sets, losing 6-3, 6-1, 7-6 (5). Choinski’s match was delayed due to rain, allowing him to participate in the tournament.

His coach and girlfriend, Sophia, provided vocal support from the players’ box, motivating him throughout the match. Choinski remarked on her influence, saying, "She always tries to help me, tries to keep me positive, for sure." Despite having chances in the first set, he acknowledged the challenge posed by his opponent's aggressive play.
