CHANGZHOU, Jiangsu Province - Four-time world champion Lin Dan of China suffered his third loss in this season as he was stopped by teammate Chen Jin in the semi-finals at the China Masters on Saturday.

Earlier, the only non-Chinese top four in men's singles Peter Hoeg Gade of Denmark was ousted by Chinese Chen Long. Therefore, Chinese shuttlers had secured one-two in men's singles no matter what the result of Lin-Chen clash is.

Lin, who blast past Japan's Sho Sasaki 21-15, 21-6 on Friday, was obviously not in the form as he squandered three game points in the first game before losing it 23-25. In the second game, Lin still didn't find back his rhythm, losing quickly 15-21.

"Grand Slam" winner Lin only had two losses before the match against Chen this year, one was the final at the All-England Open to World No 1 Lee Chong Wei, the other was the second round at the Indonesia Open to Sasaki.

"Yesterday's match is against foreign player, but this match is within our team, it is different. The gold has already belonged to China," said the 28-year-old Lin.

While Chen Jin said "Lin's physical condition was not in the best, and after taking the gold at the world championships, maybe Lin's desire to win is not so strong in this tournament."

Chen Jin will play with Chen Long in Sunday's final.
