HONG KONG - Two-time Olympic champion Viktor Axelsen of Denmark wasted six match points before beating Indonesia's Anthony Sinisuka Ginting to reach the final of the Hong Kong Open badminton championships on Saturday.

Second-seeded Axelsen took only 15 minutes to win the first set 21-9 and pulled ahead 20-13 in the second. However, Ginting stormed back to make it 20-19 and Axelsen, showing his left side of his back to the referee, immediately called an injury timeout.

After receiving some quick treatment, Axelsen returned to the court to kill off the match 21-19. "I'm very happy with 90 percent of the match," he said.

"But not the last 10 percent. I made too many bad decisions in the second set when he had improved a lot.
