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. The 29-year-old American rates this year the toughest of his career, dogged by illness and injury, but he is still world No 15 and showed plenty of spirit in beating Yen-Hsun Lu 6-2, 3-6, 6-2 in his opening match yesterday.
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."
Rafael Nadal and Andy Murray have first-round byes.
