Roger (Rasheed) and I have agreed to spend some time in the short term to help me in the journey forward in preparation for 2014 and we both are looking forward to this collaboration.
Dimitrov has made some impressive strides in 2013, having reached his first ATP final in Brisbane, where he lost to British No. 1 Andy Murray. The 23-year-old had another breakthrough performance in Madrid when he beat then-World No. 1 Novak Djokovic in the second round.
The World No. 27 is scheduled to meet Kei Nishikori in the opening round of the Shanghai Rolex Masters. He has been on a 3-match losing streak since his last win in Cincinnati and will be looking to break that streak and make a run in the second-to-last Masters tournament of the season.
