We continue our look at the eight boys and eight girls competing in the inaugural ITF Junior Masters on 3-5 April. Today it's the turn of Czech Republic's Marketa Vondrousova and Korea Republic's Duck Hee Lee.

Duck Hee Lee (KOR)

With a staggering 17 Juniors titles and two Futures titles to his name, it is hard to believe that Korea Republic's Duck Hee Lee is still only 16 years old.

The youngest boy competing in the ITF Junior Masters field, Lee is one of two Koreans alongside Yunseong Chung and his international fame is not purely down to his tennis prowess.

Lee was born deaf and his disability has stirred the interest of the world's media, not least because it has not hindered his ability to play tennis to the highest level. 

With a career-high Juniors ranking of No. 3, Lee's highlights include being part of the Korean team that finished runner-up in the 2012 World Junior Tennis Finals.

He also won the doubles title at the 2013 Grade A Osaka Mayor’s Cup (partnering Denmark's Simon Friis Soendergaard) and finished runner-up in doubles at the 2014 Asian Closed Champs (alongside China's Zheng Weiqiang). 

He picked up Futures singles titles at Hong Kong (d. Wishaya Trongcharoenchaikul) and Cambodia (d. Dekel Bar) last year and has reached a further two singles semifinals in Sri Lanka and Japan this year.

Lee's Nanjing Youth Olympic Games was ended by cramping in the quarterfinals at one-set-all against eventual gold medallist Kamil Majchrzak (POL) so he will be keen to perform better at another major ITF event on Chinese soil.
