The quarter-final line-ups for the Junior Davis Cup and Junior Billie Jean King Cup by BNP Paribas Finals are now known after all outstanding qualification issues were resolved on another compelling day of action in Antalya.

There were far more issues to settle in Junior Billie Jean King Cup today and top seeds Czech Republic had to contend with an injury scare to their No. 1 player, Nikola Bartunkova, before rallying in their doubles showdown against Argentina.

Bartunkova’s enforced retirement from her match with Luciana Moyano meant Brenda Fruhvirtova and Sara Bejlek had to defeat Lourdes Ayala and Moyano to maintain the Czech’s 100 per cent record.

This they did, which had a knock-on effect for Peru, who made it through to the quarter-finals following their nail-biting showdown against Egypt, which also went the distance.

Ultimately, Lucciana Perez and Daniela Rubio prevailed in the doubles to send the South Americans into the last eight where they will meet Japan, while Czech Republic face Mexico.

Japan are another team to have reached the quarter-finals with a 100 per cent record following their 3-0 victory over history-making Morocco, while Mexico’s passage to the knockout stage was confirmed by their 2-1 win against Hong Kong.

This was another tie decided by doubles as Karen Verduzco and Isabella Lechuga secured the win, while No. 8 seeds Thailand, who were also in contention for a quarter-final place, lost convincingly to Russia.

Russia were the runaway winners of Group D and boast a perfect record heading into the quarters where they will face Canada, who held their nerve in the doubles to post a comeback victory against Hungary.

It was Victoria Mboko and Martyna Ostrzgalo who hauled Canada over the line after Hungary surged into the lead following a singles victory for Vanesa Dalma Danko over Naomi Jianuo Xu. This win, coupled with Turkey’s defeat to Germany, saw Canada through.

Winners of Group B were Germany, who head into tomorrow’s quarter-final showdown with Morocco with three wins from three following their 2-1 triumph over Turkey. This was another full-blooded tie determined by doubles as Marie Vogt and Ella Seidel prevailed.

In Junior Davis Cup, the main qualification conundrum centred on Group B, with Mexico and Russia ultimately progressing. Mexico advanced despite losing their first match of the week to Bulgaria, while Russia overcame Tunisia to book their last-eight spot.

Russia have grown accustomed to playing a card game known in their homeland as Stupid prior to their matches, but there was no lack of on-court intelligence as they triumphed 3-0.

Russia, according to Danil Panarin, who joined forces with Maxim Zhukov to great effect in the doubles, have effectively been playing knockout tennis for the last two days after losing their opening tie to Mexico.

“I am very happy for myself and for my team because this is a prestigious competition and it is the first time that I represent my nation,” Panarin told itftennis.com. “I am enjoying this place and I like that I have the chance to represent Russia.

“We were very upset after the first tie because we had a lot of chances to beat Mexico, but we had it in our mind that we can still get through.

“Our coach told us before this tournament that every game and every set counts, and if you lose the first tie you can still get out of the group. We just had to push it and now we still have a chance.”

Russia will face Canada, who suffered a 3-0 defeat to France, in the quarter-finals, while Mexico take on Germany, whose stock continues to rise under the stewardship of two-time Grand Slam doubles champion Philipp Petzschner. They defeated Argentina 2-1.

The remaining quarter-final clashes see the other teams with three wins from as many ties, top seeds Czech Republic and No. 2 seeds France, take on Argentina and Japan respectively.
