British number one Katie Boulter suffered a swift defeat in the second round of the US Open, losing 6-1, 6-0 to Czech seventh seed Karolina Muchova in just 58 minutes. The match was moved from an outer court to the larger Louis Armstrong Stadium in New York due to heavy rain. Boulter struggled throughout, winning only one game and committing eight double faults while failing to hit a single ace. She managed to win just 33% of the points on her first serve and failed to convert any of the seven break points she faced, making 22 unforced errors compared to Muchova's nine. Muchova, who reached the Wimbledon final earlier this year, used a mix of smart drop shots and powerful groundstrokes to dominate the match, recording 14 winners in the process. In contrast, Francesca Jones had more success after her first-round match against Poland’s Magda Linette was interrupted by rain on Tuesday. Jones had taken the first set 6-4 before the rain forced a delay. When the match resumed on Wednesday, Linette took control of the second set, winning it 6-0 in just 28 minutes. However, Jones fought back in the third set, breaking Linette’s serve at 2-1 and ultimately securing the win. This victory marked Jones' second Grand Slam match win and sets up a second-round clash against either American 14th seed Iva Jovic or Poland’s Magdalena Frech. Former world number five Daniela Hantuchova offered advice to Boulter on BBC Radio 5 Live, suggesting that if she were in Boulter’s position, she would review her game plan with her team, focusing particularly on her serve and physical conditioning. Boulter has had a challenging season, managing only two wins across the four Grand Slam tournaments and securing just two victories in the six matches she has played since her first-round exit at Wimbledon. She recently married Australian tennis player Alex de Minaur in July. Britain’s Jan Choinski also failed to advance past the first round, losing 6-3, 6-1, 7-6 (7-5) to Dutch player Botic van de Zandschulp. His match was also postponed to Wednesday due to rain, adding to the logistical challenges faced by players and organizers during the tournament.
