Great Britain's Dan Evans reached the third round of the Nottingham Open with a battling win over teenage compatriot Henry Searle.
Second seed Evans was well matched by the 18-year-old and after his 7-6 (7-4) 7-6 (7-5) win said the reigning Wimbledon junior champion will be "a hell of a player".
Searle, the current world number 630, is yet to make his debut at ATP Tour level, but underlined his potential in a tight contest.
"He's obviously very good," said Evans.
"I'm just happy to come through to be honest - it's not the draw I wanted to see when I saw I was next to his name.
