Forty-eight days after Emma Raducanu’s last victory on the tour, she finally has another – and both wins happened to come against the same opponent: 22-year-old American college graduate Peyton Stearns.

On Tuesday, these two young players fought out a sweaty, tense and unpredictable match in the opening round of the WTA 500 event in Seoul.

Despite some excellent points here and there, it wasn’t the cleanest of contests, with the combined total of unforced errors running to a hefty 110 in just two sets.

But Raducanu showed no little grit to edge through in a pair of tie-breaks: 7-6, 7-6. On a physical level, she must have been desperate to avoid a deciding set, because those first two had already occupied a draining two hours and 43 minutes.

“I don’t think either of us were playing particularly great tennis,”  said Raducanu, who will now face China’s Yue Yuan in the second round on Thursday. “It was more of a dogfight. The conditions were very humid so it was a tough two sets. If it had gone to three it would have been very interesting. Peyton has had a lot more tennis under her belt than me in the last couple of months so I am just proud of finding a way.”

In her on-court interview, Raducanu also explained that “the balls were bouncing around all over the place”, which might seem like a prerequisite for this sport. What she meant was that the courts were lively, setting up a lot of high rallies that favoured Stearns’s heavy top-spin.

“It jumps a lot off the court and gets very high,” Raducanu clarified in the interview room after the match “It felt like playing at altitude a little bit. I lost my rhythm on serve, and everything followed from that. It just became ‘Who’s gonna tough it out and win the mental battle?’ None of us were particularly happy with the way we were playing but some matches are like that.

“At 5-6 down [in set two], I was struggling to get the ball in the court. I was just like ‘If I’m gonna lose the set, I’m gonna hit the ball, because this is kind of miserable the way I’m playing right now, so just go for it.’ I think I won seven points in a row. I was just aiming to dictate the first shot so that she wasn’t able to hit so spinny and so high. In the tie-break I think I was just caring less to be honest and it paid off.”

The world No 48, Stearns has plenty of upside to her game, including one of the biggest forehands on the tour. But she also shows a tendency to become tight and tentative, especially when serving.

Throughout this match, there was zero advantage in being the server. Both women finished with no better than a 50 per cent success rate in their own games, as well as matching tallies of eight double-faults apiece.

As neither player looked comfortable as a front-runner, there were regular swings in momentum. Raducanu won four of the first five games against a misfiring opponent, but was then caught unawares by a Stearns resurgence, losing the next four games on the bounce.

In another up-and-down sequence, Raducanu also served for victory in the second set at 5-3, only to slip back to 5-6 amid that “miserable” sequence of misses that she mentioned earlier. The result thus came down to the two tie-breaks, and it was Raducanu who had the cooler head in those moments.

Her reward will be a decent boost on the rankings ladder, whatever happens against Yue on Thursday. Her area of the table is so crowded that the 60 points she earned by reaching the last 16 will carry her up something like ten places, to around No60 in the world.

Raducanu had only played two other matches over the seven weeks since her last meeting with Stearns, which delivered a 7-6, 6-2 win in Washington. She was eliminated in the next round of that tournament by eventual champion Paula Badosa, and then opted out of playing qualifying in either Toronto or Cincinnati. For context, Stearns has played 11 matches in that time, winning seven of them.

After going to New York for the US Open, Raducanu was beaten in straight sets by former Australian Open champion Sofia Kenin. In a tearful post-match press conference, she acknowledged that she had gone into the tournament with a shortage of matches, and said “I think I can learn from it and manage my schedule slightly differently.”

With Beijing to play next, and then Hong Kong, there’s an opportunity for Raducanu to gather some significant court-time before the British women travel to Malaga in November for the Billie Jean King Cup finals.

How has Raducanu performed this year?

The Briton has had broadly positive results since returning from a lengthy injury lay-off last year. She helped steer Great Britain to a spot in the Billie Jean King Cup as they beat France and carried on that form in Stuttgart in April.

She eventually lost to Iga Swiatek in the quarter-finals but did beat three-time major winner Angelique Kerber in the opening round.

However, it has not been all plain sailing for Raducanu since her return to the WTA tour. She has failed to win any back-to-back matches until reaching the third round of Indian Wells.

On grass, the Briton was impressive this summer by reaching the semi-finals in the Nottingham Open where she was beaten by fellow British player Katie Boulter. She made the round of 16 at Wimbledon following wins over Elise Mertens and Maria Sakkari before being defeated by qualifier Lulu Sun.

At the Citi Open in Washington DC, she narrowly missed out on a semi-final spot after losing to Paula Badosa in a three-set match having dispatched eighth seed Mertens earlier in the tournament.

Raducanu aiming to bounce back after US Open exit

Good morning, welcome to our live blog of Korea Open action. Britain’s very own Emma Raducanu plays this morning.She will be on once Sloane Stephens and Hayley Baptiste have finished. After a dismal first-round exit at the US Open, Raducanu is looking to make amends in Seoul.

The world number 70 did not even make the original Korea Open main-draw list, but thanks to Iga Swiatek, Jessica Pegula, Elena Rybakina, Karolina Pliskova and Emma Navarro withdrawing, Raducanu earned a golden ticket to her first competition since Flushing Meadows.

The Briton has fond memories of Seoul – the Korean Open was the site of her first semi-final appearances on the WTA tour, winning three matches in a row before coming unstuck against Jelena Ostapenko in 2021.

Raducanu faces Peyton Stearns, who has had a moderate year. Currently ranked world number 48, she has made progress by claiming the Morocco Open this season but has yet to secure another title.

Her grand slam performances have been less impressive, with early-round exits in all four majors. The American will be eager to get back to winning ways against the Briton.

Raducanu and Stearns will be squaring off for the second time in a matter of weeks after never previously crossing paths on the WTA tour before this year.

Instead, the duo faced each other at the end of July in the last 16 of the Citi Open, where Raducanu was victorious in straight sets.

The Briton saved five of the six break points that Stearns managed to fashion, and that two-set victory actually represents Raducanu’s most recent win on the WTA tour – the Briton subsequently lost a three-set thriller to Paula Badosa in the quarter-finals.

Who do you think will come out on top? Stay with us for all the action.
