British number two Dan Evans won for the first time in his career at the Paris Masters as he aims to finish his ATP season on a high.
Evans, 32, won 6-3 3-6 6-4 against 21-year-old American Brandon Nakashima to reach the second round of the final regular event in the men's season.
The world number 27 will play Greek fifth seed Stefanos Tsitsipas next.
Jack Draper also plays on Tuesday as he aims to join fellow Britons Evans and Cameron Norrie in the last 32.
Fast-rising 20-year-old Draper, who has moved into the world's top 50 this year, plays France's Arthur Rinderknech.
