Emma Raducanu impressively fought back at the Transylvania Open to earn her first win since becoming the US Open champion.

The 18-year-old British player was beaten in the second round at Indian Wells following that historic victory at Flushing Meadows last month.

But the world number 23, seeded three in Romania, had the perfect response against 30-year-old Slovenian, Polona Hercog.

Playing in her father Ian's homeland for the first time, Raducanu won 4-6 7-5 6-1 to move into the second round of the competition.

Despite being a Grand Slam champion, this was her first WTA tour win and although no fans were allowed in Cluj-Napoca due to Covid-19 restrictions, her 88-year-old grandmother Niculina, who resides in Bucharest, was present for the hard-fought victory.

Raducanu, still looking for a new coach after parting with Andrew Richardson following her US Open triumph, asked for patience before the WTA 250 event.

Yet, playing a far more experienced opponent in a match lasting two hours and 29 minutes, she managed to prevail and eventually win the grueling encounter to set up a match with Romania's world number 106, 28-year-old, Ana Bogdan.
