Emma Raducanu survives late wobble to see off Moyuka Uchijima at Korea Open

• Raducanu wins in straight sets despite first serve struggles

• Briton will face Yanina Wickmayer in second round

Emma Raducanu advanced into the second round of the Korea Open as she saw off Japan's Moyuka Uchijima in straight sets.

The British number one, currently at 77 in the world rankings, beat 126th-ranked Uchijima 6-2 6-4 in an hour and 18 minutes in Seoul, dominating for much of the contest before surviving a fightback by her opponent.

Raducanu will next face Belgium's Yanina Wickmayer, who had earlier defeated Czech Linda Fruhvirtova 6-1 6-4.

The 19-year-old will be eager to extend her run after making a second-round exit at last week's Slovenia Open, her first tournament since the defence of her US Open title ended in round one.

After Uchijima held serve in the opening game of the match, Raducanu won the next five in a row en route to claiming the first set.

She subsequently broke Uchijima in the opener of the second and twice more again as she surged into a 5-0 lead.

Having looked entirely comfortable, the sixth seed was then broken when serving for the match, and Uchijima's response continued with three more games to take the score to 5-4.

Uchijima then had break point at 40-30 up in the 10th, only for Raducanu to produce a couple of aces before wrapping up the victory.

The moment the win was secured

Raducanu gets over the line 6-2, 6-4

Raducanu wins the crucial first point of the game on serve, which should settle her down and allay any internal doubts. Uchijima responds though, with a forehand down the line spooned up for a smashed winner. 15-15.

An unforced error from Uchijima makes it 30-15 to Raducanu, though. Raducanu's errant first serves starting to come back to bite her, and Uchijima gets it back to 30-30 on her second serve.

Raducanu then serves an untimely double fault, her FIFTH of the match, and Uchijima has break point!

Just when she needed it though, Raducanu serves up an Ace to send the game to deuce. And then another Ace! Raducanu has her third match point.

Uchijima can't control the return and that is Raducanu over the line. Three accurate first serves when required. A collapse from 6-2, 5-0 would have been unthinkable.

Raducanu* 6-2, 5-0 Uchijima (*denotes next server)

Uchijima really struggling to keep pace now, and Raducanu has two points for a 5-0 lead in this second set. Raducanu's power is proving overwhelming, and a forehand that is too hot to handle puts the Briton within one game of winning the match in straight sets.

08:39 AM

Raducanu 6-2, 4-0 Uchijima* (*denotes next server)

Raducanu's cruise through the second set continues, as she holds serve against a rather dispirited Uchijima now. That first serve percentage is also slowly creeping up.

08:01 AM

Raducanu 3-1 Uchijima* (*denotes next server)

Raducanu's second serve proving sufficient again, but she will want to land a higher percentage of first serves against stronger opponents.

07:43 AM

Raducanu's long climb to the top

Emma Raducanu continues her bid to climb back up the rankings with today's first-round clash against Moyuka Uchijima at the Korea Open.

The world No 77, who is coming off a second-round exit at the Slovenia Open last week, opens her campaign in Seoul as sixth seed against a player 49 places below her in the WTA Rankings.

In Slovenia, Raducanu suffered another injury scare during her disappointing loss to Germany's Anna-Lena Friedsam in Portoroz.

Raducanu took a wild card into the low-key event and was the top seed but fell to a 7-5, 0-6, 6-3 defeat.

The British No 1 began well and opened up a 5-3 lead in the first set over qualifier Friedsam, who is ranked down at 213, although she has been a top-50 player.

Raducanu then lost four games in a row and began to look uncomfortable in her movement.

She took a medical timeout at the end of the first set and had her left thigh heavily strapped but breezed through the second set only to come up short in the decider.

The winner of today's clash with Uchijima will face either newly-crowned Chennai Open winner Linda Fruhvirtova or Yanina Wickmayer in the second round with Magda Linette a projected quarter-final opponent.
