Tennis: Nishikori upsets Berdych to win Kooyong Classic

Japan's Kei Nishikori emulated the feat of coach Michael Chang as he defeated Tomas Berdych 6-4, 7-5 on Saturday to win the Kooyong Classic.

Chang, newly-appointed coach of the Japanese number one, was in the stands for his protege's success. He won the pre-Australian Open trophy himself three times in the late 1990s.

Nishikori, ranked 17th, needed all of his resources to stage his giant-killing act over the world number seven from the Czech Republic.

Berdych came to the final of the eight-man event with an undefeated record after actually beating Nishikori in a group match 48 hours earlier.

But due to the late withdrawal of France's Richard Gasquet from the final due to fatigue, Nishikori was re-inserted into the field, getting the chance to vie for the title as the start of the Australian Open looms on Monday.
