Top seed Martin Lee was philosophical after his shock drubbing by 17-year-old Alex Bogdanovic in the second round of the National Championships in Bolton.
Lee, the British No. 3, lost 7-5 6-0 to a man ranked 951 places lower in the world rankings.
The East Preston-based ace insisted the manner of his defeat would contribute to his major goal of cracking the world's top hundred.
Lee said: "I learnt a very big thing today - something to do with my mind - which I would not have learnt if I'd won.
"I tried my hardest on every point but he didn't give me a sniff. He started off well and just kept playing the same way through the whole match. He certainly surprised me how many winners he hit."
Bogdanovic meets James Nelson in the last eight.
