Britain's Jack Draper had his bid for a maiden Grand Slam quarter-final ended by Russian eighth seed Andrey Rublev in the US Open fourth round.
Draper, 21, pushed Rublev hard in a physical encounter in a humid New York, but faded to lose 6-3 3-6 6-3 6-4.
Nevertheless, Draper will look back with pride on the way he was able to put recent injury issues behind him.
Draper, who was a doubt for the event with a shoulder injury, was the last Briton remaining in the singles.
Reaching the last 16 was the best run of Draper's fledging career at a major tournament and provides further encouragement going into next season.
Rublev, 25, goes on to face either compatriot Daniil Medvedev, who is seeded third, or Australian 13th seed Alex de Minaur.
