In Asia, Nam is now ranked fifth behind Chan Seong Hong, Hee Duck Lee, and Yunseong Chun of South Korea and Japan's Akira Santillan.
This is the highest ITF Junior ranking a young Vietnamese player has ever achieved, and is commensurate with Nam's efforts, as well as the investments he has made in the right direction as one of Vietnam's most promising young tennis talents.
"The new ranking will help me immensely during upcoming events, especially in the junior Grand Slam tournaments," said Nam.
If Nam maintains his rank among the top 15 young players in the world, he will certainly be seeded at the Junior French Championships held at Roland Garros in late May and could avoid strong opponents in the early rounds.
Nam, who is training in the southern province of Binh Duong, will leave for Bangkok, Thailand soon to take part in the Men's Future from April 27 to May 3.
During the Sarawak Chief Minister's Cup in Malaysia last month, the 18-year-old had won both the men's singles and doubles event trophies.
