Two Indonesian badminton players, Jonathan Christie and Anthony Ginting, secured their semifinals tickets in the men’s singles after beating their opponents in straight games on Sunday at the Istora Senayan, Jakarta.

Christie dominated the match against Hong Kong shuttler Wong Wing Ki, winning 21-11, 21-18.

Wong, who struggled to catch up with his opponent's leads - backed by an almost full-house Istora - lost mostly due to unforced errors.

Christie said his loyal supporters helped him win the game.

"Our supporters made Wong nervous. He couldn't shoot right at the beginning of the game, much to my benefit," he said after the game.

He will meet the winner between Japan’s Kenta Nishimoto and South Korea’s Son Wan-ho on Monday.

Meanwhile, after defeating world number-four Kento Momota of Japan on Saturday, Ginting seemed to get stronger, beating Chen Long in a straight 21-19, 21-11.

Ginting, who suffered cramps and was forced to retire during the finals of the men's team competition, controlled the whole game with his strong smashes and defense.

Thanks to several unforced errors by Chen, Ginting convincingly secured the game.

Ginting said his strategy to aggressively and confidently attack his opponents had helped him.

He is set to play against Chinese Taipei's Cou Tienchen on Monday.

"I don't want to think too much about tomorrow's game. I want to focus on maintaining my concentration, mental and physical condition," he said. (yan)
