Andy Murray has been knocked out of the Winston-Salem Open but British number one Dan Evans is through to the third round in North Carolina.
Murray, 34, was beaten 7-6 (7-4) 6-3 by American Frances Tiafoe, while 31-year-old Evans overcame Frenchman Lucas Pouille 3-6 6-4 6-1.
Evans, who missed the Tokyo Olympics after a positive Covid-19 test, faces Richard Gasquet in the last 16.
The players are preparing for the US Open which begins on 30 August.
Evans ended a run of four successive defeats since his third-round exit at Wimbledon with victory over Pouille.
