Spanish world number one Rafael Nadal has reached the China Open quarter-finals with victory over Russian Karen Khachanov.
Nadal, who won his third US Open title last month, triumphed 6-3 6-3 in Beijing.
The 31-year-old broke Khachanov, ranked 42 in the world, in the fourth game and looked in total control thereafter.
He will face big-serving American John Isner next, who beat Argentina’s Leonardo Mayer 6-0 6-3.
