Ena Shibahara

The former US Open champion, who opted to miss the French Open to focus on preparing for the grass-court season, overcame the Japanese 6-1 6-4 in her first match since losing to Maria Lourdes Carla at the Madrid Open in April.

It was also Raducanu's first win on surface since the 2022 Wimbledon Championships, having missed last year's grass-court season after undergoing wrist and ankle surgery that, at one point, left her confined to a mobility scooter.

Although, the 21-year-old was left unhappy with several questionable decisions by umpire Carvalho, suggesting some of the calls were deliberately made in order to extend the contest.

It comes just 24 hours after fellow Briton Harriet Dart slammed "pretty appalling" officiating during her defeat to Katie Boulter in Nottingham, where electronic line-calling technology is not in use.

Nevertheless, Raducanu was pleased to eventually prevail and book her place in the second round.

"I feel like I was playing two v one on court, it was insane," said Raducanu. "I would have used probably at least four challenges!

"I think a lot of the time they go both ways. Today, I felt they were all against me, but it just makes me feel better that I managed to beat her and the umpire as well.

"It is difficult when there is no challenge, but it is something everyone has to deal with. You can be fortunate in some ways. Maybe it was just trying to make the match more competitive.

"It's something I had to deal with and overcome. I am very pleased with the attitude I came out with from the get-go and also having to deal with the adversity.

"I haven't played in a match for a while. Playing someone who comes through qualifying and is used to the conditions, I am very pleased to have won that match."

The world number 209 was also thrilled to get a win under her belt on home soil, and set up a last-16 clash with Ukrainian Daria Snigur, who defeated second seed Marta Kostyuk.

"An element of me forgot what it was like to play at home and have that support behind me, and it is amazing," she added. "It's a great feeling.

"I am very lucky to have great support wherever I play, but it's not quite like coming and playing in the UK. It's something that me and all the Brits cherish and look forward to every year."

Swiatek, who won the title in New York in 2022, made just six unforced errors as she triumphed 6-0 6-1 against her Japanese opponent. 

A dominant opening service game set the tone for the encounter, with the world number one racing into a 4-0 lead in double quick time before closing out the first set. 

Shibahara, however, would get her first and only game on the board early in the second, but had to do so by saving three break points to hold her serve. 

From then on, Swiatek took control, dropping just four points in the final three games to comfortably progress to the next round without breaking a sweat.

Swiatek will face the winner of Elisabetta Cocciaretto and Anastasia Pavlyuchenkova's encounter for a place in the quarter-finals of the competition on Saturday.

Data Debrief: Super Swiatek rolls on

Swiatek is the fifth player in the Open Era to reach the round of 32 in 19 consecutive women’s singles grand slam tournaments, after Martina Navratilova, Steffi Graf, Arantxa Sanchez Vicario and Conchita Martinez.

The Pole is also the youngest player to win 20 of her first 22 second round appearances in women’s singles grand slam since Victoria Azarenka in 2012, who won 21 of her first 22 second round appearances.
