Hoang Thien put up a good fight against defending champion Cecil Mamiit in the first round of the men's singles tennis tournament at the South East Asian Games in Indonesia Thursday.
The 16-year-old Vietnamese, ranked 130th in the International Tennis Federation juniors rankings, lost the first set 2-6, but stepped his game in the second set and won it by the same margin.
The 35-year-old Filipino, a four-time SEA Games champion, used all his experience to take the final set 6-3.
Speaking after the game, Mamiit said, "He [Hoang Thien] is only 16 years old but he is very powerful and moved very fast during the match. He will become a SEA Games champion in the future."
