One rest day worked for Chong Wei

World number one badminton player Lee Chong Wei said the easy win he recorded over Hu Yun at the quarter final competition of the 2013 Malaysian Open Super Series Badminton Championship was due to the advantage of a one day rest he had.

The 30-year-old player easily beat Hun Yun 21-12 and 21-9 in 24 minutes.

"Everyone knows I did not play yesterday after my opponent, Boonsak Ponsana withdrew as he was not healthy. Hu Yun also gave less competition today," he told reporters after the match at Stadium Putra, Bukit Jalil, here, today.

Commenting on the semi-final match against Jan O Jorgensen of Denmark tomorrow, Chong Wei who was hunting his ninth title at the championship, said he must be alert as the player had a strong fighting spirit.

Jan O Jorgensen advanced after beating another national player Liew Daren 19-21, 21-13 and 21-17 in 62 minutes.

Chong Wei held a 5-1 record on Jan O Jorgensen in their five previous meetings.
