SHANGHAI, Nov. 19  -- Lu Lan from China beat her teammate Wang Lin at ease to advance to China Open Badminton quarterfinals here on Thursday.

    World No. 3 Wang Lin seemed affected by injuries, and she lost the match without causing Lu much trouble.

    Wang tried to recover at the beginning of the second set, but Lu copied her performance, refusing to give Wang any chance to lead.

    Wang made too many unforced errors afterwards, and Lu succeeded in securing her victory 21-10.

    "I think I did my best today," Lu said. "I tried to follow my own rhythm and keep active through the match."

    Wang didn't look disappointed after the loss. She said she was satisfied with her performance this season, expecting to keep moving ahead.
