Andy Murray earned his first singles victory at Tour level since January with a three-set win over Tennys Sandgren in the first round of the Zhuhai Championships in China.
Murray continued his comeback from hip resurfacing surgery by winning 6-3 6-7 (6-8) 6-1.
Defeating the world number 69 showed progress from Murray having lost to the same man in North Carolina in August.
He will play Australian world number 31 Alex de Minaur in the second round.
Murray, 32, said at the Australian Open that the ongoing problem with his hip could have forced him into retirement.
