Emma Raducanu showed patience and determination to claim her first ever WTA tour level victory, and first from a set down.

The British world number 23 faced the world number 124 in the opening round of the Transylvania Open.

Raducanu did pass up a 4-1 lead in the opening set to lose it 6-4. However, the teenage talent fought back from there. She won seven consecutive games across sets two and three before claiming victory 4-6, 7-5, 6-1.

Incredibly, Raducanu had never previously won a match on the WTA tour. She of course had wins at Wimbledon and the US Open, as well as at the Chicago 125 event in August.

But on the WTA tour, encompassing 250 to 1000 level events, Raducanu had not yet won a match before today.

The 18-year-old only made her WTA tour debut back in June at the Viking Open in Nottingham.

In addition, Raducanu has since claimed all of her Slam victories in straight sets, and lost after losing the first set in her three other WTA event appearances.

So this victory is simultaneously her first on the WTA tour and first from a set down on the WTA tour.

Raducanu is the third seed at the inaugural Transylvania Open. She is seeded behind newly crowned Kremlin Cup champion Anett Kontaveit and world number 18 Simona Halep.
