The 19-year-old British number one has seen little action since losing in the semi-finals of the Pacific Life Open in Indian Wells last week to Serbia's Novak Djokovic. He twisted his ankle in his quarter-final victory over Germany's Tommy Haas, but he was still able to overcome Goldstein 6-2 7-6 (7-4) despite his injury problems and relatively lengthy break to book a thirdround clash with American Robert Kendrick.

"I was pretty out of breath, to be honest, " he said. "I was pretty tired. You know, I only hit about two and a half hours over the last six days, and the conditions here are completely different to Indian Wells."
