Chau Nguyen

School: Estancia High

Sport: Badminton

Position: Boys’ singles, mixed doubles

Class: Senior

Nguyen avenged his only loss of the season by defeating Sang Kim of Garden Grove in the singles semifinals of the Estancia tournament Saturday. Kim had defeated Nguyen in the semifinals of the Garden Grove tournament, but Nguyen returned the favor in consecutive games this time. He then defeated teammate Linh Doan, 16-18, 15-9, 15-7, in the final to extend his record to 15-1 this season. “He’s learned to play with poise,” Estancia Coach Lillian Brabander said. “He used to explode when he made a bad shot and the rest of the game was history. Now he can maintain his poise for a whole match.” Nguyen has joined Doan Nguyen (no relation) to form a mixed doubles team that hasn’t been beaten this season. Estancia, the defending Southern Section team champion, is the favorite to win another title.
