2008 Korea Open - MS Final - Lin Dan vs Lee Hyun-il - 1/8
Lin had a good start to 2004, earning the BWF's number one world ranking for the first time in February. He helped China win the qualifying round of Thomas Cup and then captured the Swiss Open. He won his first ever All England Open title by beating Peter Gade in the final. He reached the semifinal of the Japan Open before going off to Jakarta, Indonesia in May for the Thomas Cup campaign.
In Thomas Cup, Lin won every match he played except his semifinal clash with Lee Chong Wei, and helped China to a third successive title in the tournament. After easy victories over Nigeria and Canada in the group stage, China defeated Thailand in the quarterfinals. Despite Lin's loss to Lee Chong Wei in the semifinals, China still managed to qualify for the final over Malaysia 3–2 and retained the title after beating South Korea 3–1.
