Precious advice from Roger Federer is unlikely to be forgotten in a hurry, and Swiss prodigy Leandro Riedi is using his pre-tournament audience with the 20-time Grand Slam champion to fuel his Australian Open ambition.

Riedi, who is seeded No. 6 at Melbourne Park, cruised into the third round of a Junior Grand Slam for the first time following a commanding 6-3 6-2 victory over Belgium’s Alexander Hoogmartens.

It was the perfect way for Riedi to celebrate his 18th birthday, and while his debut showing at the Australian Open is proving an education, what preceded his adventure Down Under was mind-blowing.

Along with fellow Swiss players Jerome Kym and Dominic Stricker, Riedi was invited to stop off in Dubai prior to arriving in Australia for a training camp with Federer – an opportunity he seized with both hands.

“It was a once in a lifetime opportunity,” Riedi told itftennis.com. “It was unbelievable. We went to Dubai and trained with the best player of all time. I was so grateful and so happy.

“I learned a lot from Roger and practice was really fun. He gave me some great advice about how to look after my body and about the mental side of the game.

“I asked him about playing and winning in the fifth set, how hard it is and his mindset in that moment. We talked, talked and talked. It was so enjoyable.

“Building on that, being here at the Australian Open, it’s really fascinating to see all the professional players and their coaches and observe how they work in the gym, for instance, and how they eat. It’s so special.”

While Jeffrey von der Schulenburg, another Swiss player and the No. 4 seed in the boys’ draw, has already exited the competition, Riedi, who will play Latvian No. 12 seed Karlis Ozolins for a place in the quarter-finals, and Stricker remain.

All three players are ranked within the top 11 of the ITF World Tennis Tour Junior Rankings presented by IMG Academy. Factor in Kym also – a member of the victorious Switzerland team at the 2017 ITF World Junior Tennis Finals in Prostejov – and Swiss tennis would appear to have a bright future.

“From the rankings it is looking really good,” said Riedi. “Jeffrey and Dominic are really good people and they are playing really good tennis. They have a big future ahead of them.

“I love practicing with them. I practice more so with Dominic as Jeffrey trains elsewhere in Switzerland, but it is great to have such competition in Switzerland and hopefully we can push each other to the top.”

As Riedi advanced to the third round, four more seeded players bowed out of the boys’ draw. Japan’s Shunsuke Mitsui, Kwololwam Montsi of South Africa, China’s Hanwen Li and Frenchman Terence Atmane also slipped to defeat on Monday, losing to Czech Republic’s Martin Krumich, France’s Timo Legout, Arthur Fery of Great Britain and Russian Egor Agafonov respectively.

Top-ranked girls were not immune from suffering a similar fate as top seed Elsa Jacquemot of France can testify. Jacquemot, who spoke on Saturday of relishing the pressure of her No. 1 seeding, crashed out following a 7-5 4-6 6-3 defeat to Germany’s Alexandra Vecic.

Jacquemot was not alone as No. 6 seed Maria Bondarenko succumbed 6-3 5-7 7-6(8) to Czech Republic’s Darja Vidmanova and Canada’s Melodie Collard, the No. 10 seed, bowed out after losing 4-6 7-6(5) 6-3 to France’s Aubane Droguet.

Junior world No. 31 Droguet is 12 places below Collard in the world rankings but made a mockery of those statistics to reach the third round at a Junior Grand Slam for the first time.

Droguet is following in the footsteps of her brother Titouan who competed here in 2018, and despite not being completely satisfied with her performance, a showdown with No. 8 seed Polina Kudermetova awaits for a place in the quarter-finals.

“I am really happy because I have only ever passed the first round at a Junior Grand Slam before,” Droguet told itftennis.com, who cites Canada’s Bianca Andreescu as the figure she most aspires to be. “I wasn’t happy with my performance, however, because I was really tense.

“But I dealt with those feelings and had my tactics. I didn’t play my own game and that’s disappointing but I play to win and that’s the main thing.”

Kudermetova advanced to round three after overcoming wild card Erika Matsuda, while fellow seeded players Ane Mintegi del Olmo of Spain, China’s Zhuoxuan Bai and Indonesia’s Priska Madelyn Nugroho also progressed.
