Andy Murray was knocked out of the Zhuhai Championships after suffering a three-set defeat against Australia's Alex De Minaur in the last 16.
Despite taking the opening set, Murray eventually fell 4-6, 6-2, 6-4 in a match that lasted over two hours and 42 minutes.
"Physically, I was struggling," he said. "My level dropped off a little bit and he capitalised on that."
Murray had earlier secured a three-set win over Tennys Sandgren in the first round of the Zhuhai Championships, making it his first singles victory on the ATP Tour since January.
