There were impressive reminders across Roland Garros on Wednesday as to why Austrian Lilli Tagger is considered an emerging talent worth keeping a close eye on in the future.

From her stylish backhand, which the 17-year-old strikes one-handed, to her outstanding touch at the net, Tagger has developed a formidable all-court game.

She deployed this with great success to win both of her Roland Garros girls’ singles and doubles matches in Paris when continuing her superb run in the prestigious event.

But the tremendous tennis of Tagger, who defeated Nellie Taraba Wallberg 6-2 6-3 to reach the quarter-finals, was not the sole reason fans were drawn to her matches at Roland Garros.

Those with a keen eye will also be aware Tagger, who has worked with 2010 Roland Garros champion Francesca Schiavone, recently posted a win of growing significance.

In late March the right-hander clinched her first ITF Tour senior title, a W35 tournament in Terrassa, Spain, by beating Lois Boisson 7-6(4) 6-3 in the final.

That Lois Boisson? On the same day the Frenchwoman continued her astonishing run at Roland Garros to reach the women’s semi-finals, Tagger also served notice of her potential.

When asked about Boisson’s performance to upset Mirra Andreeva and her own win over France’s new No. 1 ranked woman, Tagger’s eyes widened as she smiled.

“Of course, it's incredible because I played against her recently and it was a really tough match,” she said.

“She was a really good player and she had an incredible forehand and was playing very good on clay court. And I think it's an inspiration to see her playing already there.

“It means all the players here (in the juniors) can have the level to arrive there. We just (have to) keep working and try to get there.”

Tagger, who later combined with Mia Pohankova to defeat Victoria Luiza Barros and Teodora Kostovic in a thrilling girls’ doubles, will play No. 12 seed Julia Stusek in the quarter-finals after the German defeated Beatrise Zeltina 6-2 4-6 6-3.

While Austrian star Dominic Thiem had a superb one-handed backhand, Tagger said that was not the reason for her decision to switch from a double-hander as a 12-year-old.

Tagger earned a concession from her coach that, should she win a tournament, she wanted to try the shot.

Given the way she used the weapon in both of her victories on Wednesday, it appears to have been a wise choice.

“It was my choice. I already wanted to change when I was 10, but my coach told me … it was too difficult to do it,” she said.

“And then I told him, at 12, if I win this tournament, I will change to a one-handed backhand. And I won the tournament. So I made the decision.

“It was easier for me to play with one hand than with two hands and when I was in practice, sometimes I was there just playing with one hand, so I took the decision.”

Tagger, who enjoys playing golf and also playing card games with her team, is playing in only her third junior Grand Slam tournament and is loving the experience.

“I didn't play too many junior tournaments because I didn't have the ranking to play the good ones,” she said.

“But now we're playing some of them, but not too many, because we want to try to start to play the future tournaments, so we mix them up a little bit. But, of course, playing in a Grand Slam every time is incredible.”

In other girls’ singles results, No. 1 seed Emerson Jones reached the quarter-finals at Roland Garros for the first time in three attempts with a 7-5 6-3 triumph over Charo Esquiva Banuls.

The Australian plays No. 9 seed Julieta Pareja for a place in the semi-finals, with the American progressing with a 6-2 6-2 win against Victoria Luiza Barros.

British talent Hannah Klugman has been in strong form in Paris and started brilliantly against No. 10 seed Alena Kovackova on route to a 6-0 7-5 triumph.

The eighth seed faces German Sarah Melany Fajmonova for a spot in the semi-finals after the qualifier produced a quality 6-1 6-3 triumph over Pohankova.

The remaining quarter-final features Bulgaria’s Rositsa Dencheva and Luna Maria Cinalli.
