Roig

Raducanu won 28 matches this year and reached the semi-finals in Washington, but her most impressive week was at the Miami Open in March.

The British number one reached the quarter-finals of the WTA 1000 event, beating eighth seed Emma Navarro on the way before losing in three sets to fourth-ranked Pegula.

She was coached by Mark Petchey from Miami until Wimbledon, with Roig taking over in time for the US Open.

The initial agreement with Rafael Nadal’s former coach was until the end of the season but the partnership will continue, with a training block pencilled in for the end of the year.

Raducanu told BBC Sport her three-day trial with Roig after Wimbledon was like a “black ops mission” as they tried to keep the meeting secret.

She came very close to beating world number one Aryna Sabalenka at their first tournament together in Cincinnati in August.

Roig was also with Raducanu in New York, where she reached the third round before being beaten by 2022 Wimbledon champion Elena Rybakina.

Emma Raducanu says she is “excited” to be working with Rafael Nadal’s former coach Francis Roig as she prepares for this year’s US Open.

The 22-year-old had been working with British coach Mark Petchey on an informal basis since March and has now added Spaniard Roig to her team full-time.

Roig, 57, worked alongside Nadal’s uncle Toni from 2005 to 2022 and was part of all 22 of the Spaniard’s Grand Slam victories.

“He’s obviously got a bank of experience and I’m very excited to continue working with him and to have him on my side,” Raducanu told Sky Sports.

The British number one is playing in the Cincinnati Open for the first time since 2022 this week and will face either fellow Briton Katie Boulter or Serb Olga Danilovic in her opening match after receiving a first-round bye.

Roig has joined Raducanu for the WTA 1,000 event in Ohio, which is the last tournament before the final Grand Slam of the season begins in New York on 24 August.

“It’s going really well,” Raducanu said. “It’s my second day with [Roig] here, but I did a few days in London before I came out here.”
