Murray's mission intensifies

Briton stepping up singles comeback against heavyweight field in Zhuhai

Andy Murray will be the center of attention at this week's Zhuhai Championships as the former world No 1 steps up his singles comeback against a heavyweight field in Guangdong province.

The tournament, which has relocated from Shenzhen (the new venue for the WTA Finals next month), has attracted an impressive cast to battle for a share of a $1 million prize pool - the biggest of all ATP 250-level events - at the state-of-the-art Hengqin Tennis Center.
