From the official web site:
Henman got level with Chileans as he stopped Nicolas Massu 6-3, 1-6, 7-5, winning on his second match point. Last week at the Masters in Cincinnati, the Briton was hammered by Massu's compatriot, Fernando Gonzalez.
"My attitude last week was not that good. I would get frustrated. Today, I tried to just let things happen. I lost the second set, but moved on," said Henman.
Henman earned a match point late in the third as Massu double-faulted for the ninth time. The South American then saved one match point but netted on the second as Henman advanced in two hours, 18 minutes.
