ODENSE, Denmark - World champion Lin Dan of China eased to a 21-15 21-12 win in the final of the Denmark Super Series against compatriot Bao Chunlai on Sunday.

"We know each other's game well and it was physically harder for Bao, which gave me an advantage," Lin told Reuters.

Lin made the final without any matches against seeded players, but Bao had to battle past Olympic champion Taufik Hidayat of Indonesia and second-seed Lee Chong Wei of Malaysia.

Bao, aware Lin is almost always at the top of his game, said: "I prepared well for this match, but I could not keep up physically and therefore could not compete with Lin's game."

Lin's victory leaves him well clear in the overall Super Series standings.

Denmark was round nine of the 12-tournament series which moves to Paris on Tuesday before events in China and Hong Kong next month and the finals in December at a venue to be decided.
