Andrey Rublev had a day to savour - and made up for the trials and tribulations of the day before - to win the boys' singles bronze medal and progress to the final of the boys' doubles at the Youth Olympic Tennis Event in Nanjing.

The world junior No. 1, whose position at the top of the rankings is under threat from Brazil's Orlando Luz, showed no sign of the severe cramp that effectively ended his hopes of a gold medal in the singles and mixed doubles events yesterday with two fine wins in similarly hot conditions on Friday.

The Russian cantered past Japan's Jumpei Yamasaki to seize the boys' singles bronze and go some way to making amends for his cramp-affected defeat to Kamil Majchrzak in Thursday's boys' singles semi-final.

"It feels great because I have a medal in the Olympic Games," said Rublev, but his disappointment of the previous day was still evident.

"Still I can do much better than I did," he added. "Yesterday I had a feeling like I never had before. I cramp all through my body. I didn't know I could even have this. The conditions, they were really tough to play."

Rublev's mood was further boosted by victory in the doubles. The Russian combined with Karen Khachanov to defeat his nemesis of the day before, Majchrzak, and his fellow Pole Jan Zielinski 4-6 6-3 10-8.

The duo will go for gold against Orlando Luz and Marcelo Zormann, who proved a class apart against Japanese duo Yamasaki and Ryotaro Matsumura, dropping just three games in the 55-minute encounter.

Latvia's Jelena Ostapenko combined with Lithuania's Akvile Parazinskaite to win the second bronze medal up for grabs on Friday, defeating USA's Sofia Kenin and Mexico's Renata Zarazua 6-3 7-5.

"It feels great [to win bronze]," said Parazinskaite after their triumph. "We wanted to get to the finals, but unfortunately it wasn't our best match [in the semis]. We're glad that we won today."

The Lithuanian will have another opportunity to take home a medal tomorrow when she takes on Ukraine's Anhelina Kalinina in the girls' singles bronze medal match.

"I'm very positive about it. I just have to go for it. I will do my best," said Parazinskaite of tomorrow's encounter and, asked if she would have said if someone had told her she would have walked away from this week's event with two bronze medals, added:

"I would have said I wanted two gold medals!"

Xu Shilin provided home joy by becoming the third Chinese player to guarantee herself a Youth Olympic medal in the tennis event (after Zheng Saisai and Hao Chen Tang, who clinched three medals between them at Singapore 2010) after booking a spot in Sunday's girls' singles final against Iryna Shymanovich.

"I'm really excited to get into the final," beamed Xu. "It's hot but it's the same for both of us. Before the game I did lots of preparation and the atmosphere here is great, that makes me more and more confident.

"Of course I want the gold medal but first I have to focus on the game. I hope there will be a good result."

Meanwhile, the mixed doubles semi-finals were set, with Hungary's Fanni Stollar and Poland's Kamil Majchrzak up against Jumpei Yamasaki and Qui Yu Ye, and Romania's Ioana Ducu and Argentina's Mattias Zukas set to play Jill Teichmann and Jan Zielinski in Saturday's semi-finals.
