US Open champion Emma Raducanu recorded her first WTA Tour match win in gutsy fashion against Slovenia's Polona Hercog in the opening round of the Transylvania Open in Cluj on Tuesday.
Raducanu showed glimpses of the kind of form which made her a global star in New York with a fine 4-6 7-5 6-1 comeback victory against world No 124 Hercog.
She led the opening set 4-1 but capitulated before battling back to win the next two sets and claim her first win at this level.
Speaking during her press conference, the 18-year-old said: "I feel really happy to have won that match. It was very difficult and I wasn't playing my best tennis but Polona is a great opponent, she's really experienced, so I really had to fight hard to pull that one through.
"I thought by the end of the third set I was playing some better tennis and the most important thing was I earned another opportunity to play better in the next round."

The Briton, who was knocked out in the second round at Indian Wells when she returned to action this month, was contesting just her second tournament since she stunned the sporting world when she won the Flushing Meadows title as a qualifier.
Playing in Romania - the country where her father was born and grandmother still lives - Raducanu made a storming start behind closed doors at the BT Arena due to Covid-19 restrictions.
She won the first three games and appeared to be in control of the set at 4-1 up, but the experienced Hercog rallied for a break of her own before levelling at 4-4.
The third seed lost the aggression which dominated the early part of the set, instead resorting to a defensive sliced forehand, which Hercog picked off at ease.
The Slovenian won her fourth game in a row to take the lead for the first time and then closed out the set on serve.
Raducanu stopped the run of games against her with a solid hold of serve in the opening game of the second set, but the 18-year-old struggled to break down the Slovenian, who reached a career-high of 35 in 2011.
World No 23 Raducanu saved a couple of break points to hold on to her service game in the ninth game and again two games later, but she stayed positive to square things up on her third set point.
The 18-year-old from Bromley in Kent maintained her level of intensity into the deciding set as her game began to flow nicely.
Her pace and power eventually broke down Hercog to race away with the match, winning eight out of the last nine games, to set up a meeting with Romanian Ana Bogdan in the next round.
"I know Ana a little bit. We spoke off court and she was really nice and friendly," added Raducanu. "I've never played against her and she's obviously a great opponent but I've not seen much of her."
Jaqueline Cristian went full 'Dracula' as she came from a set down to defeat Kaja Juvan in a thrilling contest, 3-6 7-6 (10-8) 7-6 (7-3).
