Vietnam's top tennis player, Ly Hoang Nam, 17, has officially withdrawn from the upcoming Australia Open 2014 juniors contest, citing unpreparedness.
It would have been the biggest international event in the career of Nam, who is currently ranked 95th by the International Tennis Federation.
However, his coach, Tran Duc Quynh explained: "Hoang Nam needs more training to gain more experience at many other international events before competing at an event of that magnitude."
Vuong Bich Thang, Director General of the General Department of Physical Training and Sports, said, "Hoang Nam is a great hope for Vietnam. He became the first Vietnamese to win the tennis title at the Asian Youth Games in Nanjing, China [last August].
"He would gain more confidence if he participated in a Grand Slam event because it is a professional tournament which has an environment of fierce competition, which would create a lot of motivation for him to improve."
However, Thang added, "I'm an official and I can't interfere with Nam's choice of events."
As planned, Nam will compete at the 50th Coffee Bowl contest in Costa Rica from January 6-11 before playing at Copa Gatorade event in Venezuela from January 13-19.
