Emma Raducanu sealed a fine first-round win at the Australian Open by defeating Thailand's world No 195 Mananchaya Sawangkaew on opening Sunday.

Raducanu, who one only arrived in Melbourne on Friday after reaching the quarter-finals of the Hobart International, was forced to scramble to get ready for the tournament.

But after a slow start she rattled off 10 of the next 11 games to storm to a 6-4 6-1 victory on Margaret Court Arena.

"I feel very happy to have gotten through that match," said Raducanu, speaking on court after her win.

"From the beginning, she was playing incredibly well - all of her returns and shots seemed to be dropping on the baseline.

"It made life very difficult and so I'm really proud of how I fought back in the first set.

"She played some incredible tennis, way higher than her ranking is currently and I'm sure she's going to do good things this year."

The 23-year-old has once again battled physical issues during pre-season, with a foot injury severely limiting her time on court, and she looked short of match sharpness in a clash with Maria Sakkari at the United Cup last week, while she beat Camila Osorio in the opening round in Hobart but then lost to world No 204 Taylah Preston.

Sawangkaew, making her Grand Slam debut, already has a lower-level title to her name this season and she made a lightning-quick start and was two break points away from a 4-1 lead in the opening set.

But Raducanu found her rhythm and surges through the next seven games before Sawangkaew stopped the rot.

The British No 1 has achieved her goal of being seeded at a Grand Slam again and she bossed her opponent to complete the win and make it a flawless 5-0 in first-round matches at the Australian Open.

Raducanu will take on world No 55 Anastasia Potapova in the second round with a potential third-round clash against world No 1 Aryna Sabalenka.

Potapova came through against Netherlands' Suzan Lamens 3-6 7-5 6-2.
