Shenzhen, Guangdong, China, 27 November 2014 | Tennis Australia

The start of the main draw at the Australian Open 2015 Asia-Pacific Wildcard Play-off (AWP) was highlighted by the defeat of both top seeds in the singles event.

Lin Zhu (CHN) was the first top seed to be eliminated by Thai veteran and former Grand Slam quarterfinalist, Tamarine Tanasugarn.

Tanasugarn was clinical in the 6-4 6-0 demolition which lasted just over an hour, and will next face Nao Hibino (JPN) on Friday. Hibino defeated Yan Wang (CHN) 6-3 6-1.

Zhu was joined in defeat by men’s top seed Hiroki Moriya (JPN); he was shocked by Indian qualifier Purav Raja.

Breaks went back and forth in the opening set before Raja emphatically clinched the tiebreak. He secured an early break in the second set before closing out a 7-6(3) 6-4 victory.

Raja will now take on Chinese second ranked male Di Wu, who defeated fellow Chinese player and good friend Mao-Xin Gong in a tough three set battle 3-6 6-4 6-3.

Wu trailed a set and a break before rallying to win the match, and has now won nine consecutive singles matches at the AWP event since 2012.

Top ranked Chinese male Ze Zhang opened his campaign with a comfortable 6-2 6-3 victory over Chuhan Wang (CHN). Zhang will be looking to go one better in 2013 after being defeated in the 2013 AWP final. Zhang ultimately qualified for the Australian Open after battling through qualifying in January.

Zhang will face Yuki Bhambri (IND) in Fridays quarterfinal, after the Indian defeated former Wimbledon junior winner Wesley Whitehouse (NZL) 7-6 (3) 6-3 in a tough encounter.

Bhambri knows the importance of the AWP event after winning the doubles title in 2013, and will be looking to add the singles title here to a growing list of tennis achievements which includes taking out the junior boys singles at the Australian Open in 2009.

In other women’s results, fourth seed Miharu Imanishi (JPN) opened her campaign with a 6-4 6-3 victory over 2012 AWP champion Yuxuan Zhang (CHN), and will take on rising Chinese star Shilin Xu.

Xu, who won the Youth Olympic Games gold medal earlier this year in Nanjing and is currently the world No.1 junior, defeated experienced Chinese Taipei player Chin-Wei Chan 6-1 6-4.

Xu and Imanishi will play in the quarterfinals on Friday.
