British number two Dan Evans produced a brave display but slipped to a straight sets defeat to John Isner in the second round of the China Open.
The 29-year-old, ranked 48th in the world, had beaten Chinese player Zhe Li earlier in the week, but
despite showing plenty of endeavour in both sets, he was beaten 7-6 (3) 7-5 by the American in just under two hours.
Evans had forced two break-point chances in the ninth game, before world number 19 Isner recovered and then clinched the set in the tie-break.
The second set continued to prove a tight affair, but Isner took a crucial break chance to lead 6-5 before closing out a hard-earned victory.
British number one Kyle Edmund had gone out in the first round following a loss to Chinese wildcard Zhizhen Zhang.
Andy Murray, though, continued his return from hip surgery to battle past fellow Briton Cameron Norrie and book his place in the quarter-finals, where he will face top seed Dominic Thiem on Friday.
