ANDY Roddick's previous visits to the Shanghai Rolex Masters - two defeats and one win, all three matches ending in retirements - reflect how frail players' bodies are at this stage of the season.

Roddick, who now faces Bulgaria's Grigor Dimitrov, plans to change his training methods. "Running myself into a wall with work and everything else, I don't know I can do that without getting hurt," he said. "I might have to work smarter from now on."
