LIUZHOU, South China - Chinese badminton star Lin Dan has called for the use of Hawk-Eye replay technology in the game to reduce disputed line calls.

Lin's petition came after last week's South Korea Golden Grand Prix were overshadowed by a series of disputed line calls.

Chinese top seed Chen Jin, who was stopped by South Korean Lee Hyun-II in the men's singles semifinals, blamed his defeat on unfair ruling by South Korean umpires. Chinese head coach Li Yongbo echoed Chen's words, saying some line calls were obviously wrong.

"We should look over the videos of all matches, or call on the BWF to adopt the Hawk-Eye technology. Disputed line calls will not exist if Hawk-Eye is used in all competitions," Lin said after his 21-15, 19-21, 21-17 victory against teammate Chen Long in the BWF Superseries Finals which is ongoing in Liuzhou, a city in south China's Guangxi Zhuang Autonomous Region.

Over the past few years, there had been calls for introducing Hawk-Eye to badminton, but the BWF, badminton's world governing body, didn't give the green light.

"We must ensure badminton a truly fair game, so we need to remedy this defect," added Lin.

The Hawk-Eye technology is now used in tennis and cricket.
