Vietnam's teenage star Nguyen Hoang Thien won the boys' singles' and doubles' championships at the Under-18 International Tennis Federation (ITF) Grade 4 competition in Hong Kong on Saturday.
In the boys' singles event, the 16-year-old Thien, ranked 145th in the ITF junior rankings, beat 188th-ranked Thai rival Krittin Koaykul in straight sets.
Hoang Thien proved his higher ranking by winning the first set 6-4; but the Thai competitor was not easy to defeat. His renewed efforts in the second set made it more difficult for the Vietnamese teenager.
It was a seesaw display between the two players until it was 5-5 and the Vietnamese contestant took off to take the set 7-5.
Later in the day, Thien paired with Kelvin Lam of Hong Kong and beat Wong Chun Hun/ Pak Yeung Long of Hong Kong 2-1 to win another championship.
Thien's father Nguyen Ngoc Minh said Thien is in good form now. His second place at the Under-18 ITF Grade 2 at China Junior 15-Xiamai 2011 late last month and his two titles at the contest in Hong Kong this week were great, but he aims to reach higher goals in Grade 1.
Therefore, Thien won't return to compete at the Vietnam International Junior Championships Prudential Cup - Bac Lieu (U18 ITF Grade 5 contest) from October 10-16 in the eponymous Mekong Delta town. He is the reigning champ at that competition.
Instead, Thien will fly to Osaka, Japan to compete at the Osaka Mayor's Cup - World Super Junior Tennis Championships (U18 ITF Grade 1 event) from October 17-23.
The event in Japan will see several leading junior players, including the world's number one junior, Czech player Jiri Vesely, and the world' number three junior, Australian Luke Saville.
Ranked 145th in the world's junior rankings, Thien is expected to face certain difficulty at the tournament in Osaka.
