Cork teenager Aaron Hill is coming to terms with his giant-killing feat against world champion Ronnie O'Sullivan in snooker's European Masters.
18-year-old Hill defeated the Rocket by 5 frames to 4 in the second round of the tournament in Milton Keynes.
Hill revealed he was motivated by O'Sullivan's comments at the recent World Championship.
O'Sullivan, en route to his sixth world title, branded young players as 'not that good'.
Hill told World Snooker he remembered the remarks before playing O'Sullivan.
"That comment was in the back of my head, a small bit. I just said to myself when he said it - 'one day I am going to show him what I can do' - I think today was the day."
From Cork City, Hill opened up a 3 frames to 1 lead, before falling 4-3 in arrears. He then levelled the match before going on to win it with a break of 78 in the deciding frame.
It's another feel-good story for Irish sport and Hill is on cloud nine.
"My childhood hero. To play him so early on, just to play him. I didn't just go out there to be happy to be there. I still wanted to win the match and if I lost the match after being 3-1 up, I would have been disappointed. I am just so, so pleased with that victory. Everyone back home, my family, friends, everyone must be buzzing. I had a quick look at my phone there and I think it's going to take me until Christmas to reply to everyone. I can't wait for the next round."
Hill added that nerves were not an issue ahead of the biggest match of his young career.
"I just said to myself before in my room, 'just go out and enjoy it' - I've got absolutely nothing to lose. "
Hill will now face former World Championship runner-up Matthew Stevens in the next round.
