British number one Katie Boulter was dumped out of the US Open in the second round as she won just one game in a 58-minute demolition by Karolina Muchova.

The match, originally scheduled to be played on one of the outer courts, was moved to the 14,000-capacity Louis Armstrong Stadium after heavy rain in New York.

But fans who had counted themselves lucky to have gained a third match on their day session ticket may have been left feeling short-changed, as Boulter fell to a swift 6-1 6-0 defeat by the Czech seventh seed.

Francesca Jones had better fortune as she returned to win her first-round match against Poland’s Magda Linette after it was interrupted by rain on Tuesday.

Boulter’s serve let her down as she hit eight double faults and no aces, while she won just 33% of points behind her first serve.

Unable to fend off any of the seven break points she faced, the 30-year-old was not helped by an unforced error count of 22 compared to just four winners.

In comparison, Wimbledon runner-up Muchova landed 14 winners and just nine unforced errors as she impressed with smart drop shots and piercing groundstrokes.

“I would be really humbled [if I was Boulter], I would sit down with my team and say ‘OK, we need to change something big time’,” former world number five Daniela Hantuchova told BBC Radio 5 Live.

“First of all, it was very obvious today that it was the serve. I feel like it needs to be cleared up because she was losing the rhythm and not using her legs. That’s the number one thing.

“If I am Boulter, I would be on the practice court tomorrow. If she still wants to invest everything into her tennis then she needs to be on the court.”

Boulter has had plenty to celebrate in her personal life this summer after marrying Australia’s Alex de Minaur, the world number seven, in July.

However, it has been a disappointing tennis season for the world number 62, with just two wins across the four Grand Slam tournaments.

Since suffering a first-round exit at Wimbledon, Boulter has won just two of the six matches she has played.

Jones had won the first set 6-4 against Linette, ranked 82nd, when the rain put a halt to proceedings on Tuesday night.

When the pair returned on Wednesday, it was Linette who appeared fresher as she raced to a 5-0 lead and wrapped up the second set in 28 minutes.

But Jones rallied back in the decider, claiming the decisive break at 2-1 before completing the victory – just her second at Grand Slam level.

She will play either American 14th seed Iva Jovic or Poland’s Magdalena Frech in the second round on Thursday.

Britain’s Jan Choinski, meanwhile, failed to reach round two as he fell to a 6-3 6-1 7-6 (7-5) defeat by Dutchman Botic van de Zandschulp in a first-round match that had also been pushed back to Wednesday because of the rain at Flushing Meadows.
