Britain's Dan Evans succumbed in three sets after pushing defending champion Roger Federer hard in an entertaining Australian Open second-round match.
Evans, ranked 189th in the world, lost 7-6 (7-5) 7-6 (7-3) 6-3 against the 20-time Grand Slam champion.
But he never looked out of his depth, impressing the Rod Laver Arena with his shot-making.
Federer will play either France's 30th seed Gael Monfils or American Taylor Fritz in the third round.
"I couldn't pull away early in the match - it helps when you can sneak in a quick break," said third seed Federer, who at 37 is aiming to become the first man to win seven Australian Open titles.
