Japan's Kei Nishikori claims AAMI Classic title after beating Czech Tomas Berdych MELBOURNE, AUSTRALIA - JANUARY 11: Kei Nishikori of Japan poses with the Kooyong Classic trophy after winning his match against Tomas Berdych of the Czech Republic in the final during day four of the AAMI Classic at Kooyong on January 11, 2014 in Melbourne, Australia. JAPAN'S Kei Nishikori took advantage of a tennis second chance to grab the AAMI Classic title today. Nishikori tuned up for the Australian Open with a 6-4 7-5 win against Czech Tomas Berdych at Kooyong. It was a staggering form turnaround after Nishikori, the Open's 16th seed, who scrounged only five games off a redhot Berdych in their semi-final on Thursday. But Nishikori was called up for the final after Frenchman Richard Gasquet withdrew with soreness. So the nimble Japanese baseliner had a shot at the title instead of being condemned to the warm-up match for third and fourth place. To win a Kooyong held even more significance for Nishikori as his coach Michael Chang was in the crowd. Chang, a past French Open champion and Australian and US runner-up, was triumphant three times in a row in the eight-man event in the 90s. Earlier, Luke Saville beat Ben Mitchell 6-3 6-4 in the battle of the Aussie young guns in the curtain-raiser duel before the final.
