Aaron Hill defeated the idol of childhood, Ronnie O’Sullivan, at the European Masters tonight.

The 18-year-old Tour Rookie from Cork defeated the six-time world champion 5-4 in a thriller at the Marshall Arena in Milton Keynes.

As a professional and in the biggest competition of his life, Hill led 3-1.

The 44-year-old O’Sullivan, who looked all out to sea in the early frames, had a mid-session break just in time.

In the first match since winning the World Championship last month, World No. 2 won three consecutive frames after the break.

But Hill listened to his nerves and abilities as he stood calmly, lined up to seal a grand victory.

Earlier in the evening, Mark Allen created a record-breaking performance to whitewash Ken Doherty.

The 34-year-old from Northern Ireland was in brilliant form in Milton Keynes. They won 5-0 at four consecutive centuries.

The 51-year-old former world champion Allen conceded just 12 points in the match. He waved at 134, 101, 141, and 145 attempts.

Only five players – John Higgins, Sean Murphy, Neil Robertson, Gary Wilson and Stephen Maguire – have previously achieved this feat.

At one point it looks like Alan will make history with a fifth ton – but it was unfortunate that he went into the pack at 46.

He wants to make money in the form of scoring seven centuries from two matches at the Marshall Arena after failing to win a title last time out.

Allen, who reached one final and six other semi-finals last season, said: “If I play like that, I’m going to have to stop a little bit this week – but we know snooker is not that straight.

“I was sure no one had done it five times in a row before the last frame, I went to the pack and finished poorly, then picked up a plant that I would not have done if it was 2-2.

“I know pink is the big shot in the frame to split the last few reds, but I had to go to the difficult plant with the promise of history.

“I hope all this is not down here! I’m very happy with the way I played, but I have to be prepared to face it when everything is not going well.

“Of course it would be nice to get some good forms and get a title, but other players want to get on board as early as this season.” Doherty said: “I was lucky – I thought he would score that fifth century in the final frame before the 46th.

“It was a very remarkable thing from Mark, I tell you. The ball does not seem to hit very sweetly.

“I have nothing to do but sit in my chair and he made it so easy – very noticeable and sharp. At least the chair was comfortable.

“I know Mark was disappointed not to win a trophy last season, but he has all the attributes and you’ll hope to see him on the winner’s list this season.”
