Dan Evans' run at the Miami Open ended in a second-round defeat by Canadian teenager Denis Shapovalov.
Evans dropped just two games in a first-round win over Malek Jaziri having earned a place in a draw as a lucky loser and led 20th seed Shapovalov by a set before going down 4-6 6-1 6-3.
Shapovalov helped Evans in the opening set with a number of errors but improved thereafter and the British number three needed treatment in the second set for a jarred ankle.
It has been a busy and successful start to the season for Evans, who is back in the top 100 less than a year after returning from his one-year ban, and he has looked a little jaded this tournament.
He battled well in the third set but was unable to prevent Shapovalov breaking serve in the third game and missed two chances to get back on level terms before ending the match in unfortunate fashion with a third double fault.
