Vietnam's badminton ace Nguyen Tien Minh lost 1-2 to Malaysian
Muhammad Hafiz Hashim in the men's singles quarterfinals of the 2010 Asian Badminton Championships in New Delhi on Thursday.
The world's seventh-ranked Vietnamese was on equal terms with the 23rd-ranked Malaysian for most of the first set before he lost it 19-21.
Minh, the only Vietnamese male badminton player who has entered the world's top 100, improved his defense and won the second set 21-14.
However, the Vietnamese player, who beat Taiwanese Sha Wen Hsu and Chinese Kai Wen in the first and second rounds, played badly in the third set and conceded it 15-21.
Minh had defeated Hashm in straight sets at the semifinals of the 2009 Chinese Taipei Gold Grand Prix,
Without world number one Lee Chong Wei of Malaysia and number two Jin Chen of China, fourth seeded Minh was expected to go far in the tournament.
Other Vietnamese male and female players had bowed out of the tournament in the first or second rounds.
