Nishikori adds Michael Chang to coaching team
Japan’s top player has already been working with Chang in Southern California the past two weeks and is scheduled to work with him for 17-20 weeks—and possibly more—in 2014. Dante Bottini, who has coached Nishikori for the past three years, will remain the world No. 17's full-time coach.
Former world No. 2 Chang has coached before, briefly working with China's Peng Shuai.
Nishikori will begin his season in Brisbane and then play the Kooyong exhibition, where Chang will join him and remain through the Australian Open. After Melbourne, Nishikori is scheduled to play Davis Cup, Delray Beach, and Acapulco.
