Shenzhen, Guangdong, China, 5 December 2015 | tennis.com.au

China’s Wang Yafan, the top seed in the women’s draw at theat the Australian Open Asia-Pacific Wildcard Play-off, progressed to the semifinals with a 6-4 6-4 victory over Japanese Shuko Aoyama.

The straight-sets victory sets up a semifinal against No.5 seed Lu Jing Jing of China.

“We played doubles together once before, so I had an idea about her play style,” Wang said of Aoyama.

“But still she fought really hard in the second set, so I had to stay focused for every point until last one.

“Right now I’m feeling a little bit tired, because I’ve been playing a lot since the US Open, but it’s something that young players have to deal growing up in their early careers, so I will push myself and try to win two more matches.”

In the other semifinal, second seed Han Xinyun will take on Thailand’s Varatchaya Wongteanchai, the fourth seed.

In the men’s draw, top seed Yoshihito Nishioka as come through his quarterfinal in straight sets while defending champion Zhang Ze was sent packing.

California-born Taiwanese player Jason Jung was responsible for the upset of the second seed, winning 2-6 7-5 6-3 to advance to the semifinals.

In a tense second set during which players were tough to separate, Jung ended up breaking serve in the 12th game – thanks to a Zhang backhand error into net – to send the match into a third.

Jung seized the opportunity to break the frustrated Zhang again at the beginning of the deciding set, and maintained his advantage to eventually serve out the win.

“I thought Zhang played really well, he served very strong. I knew I had to hold my own serve to stay in the match, so I just tried to give myself a chance, eventually he missed some first serves, and I was able to get some free points and turn the match,” said Jung, who will next face compatriot Yang Tsung-Hua.

“It definitely gives me some confidence beating Zhang, I’m looking forward to tomorrow’s semifinal.”

Meanwhile, Nishioka didn’t face any challenge in the first set of his match against Sun Fajing, winning it 6-2 after three service breaks.

Sun tried to step in the court to play more aggressively in the second set and held three break points in the fourth game, but Nishioka played excellent defence to save all three.

And with the momentum now back in his favour, Nishioka broke Sun again in the seventh game and eventually served out the match 6-2 6-4 with a love game.

He’ll face Li Zhe of China in the last four.
