The inevitable was only momentarily delayed as the rocket capitalised on his 8-1 overnight lead to confirm his place in the last 16.

Ding pulled a frame back in the 10th but the Rocket responded with an 87 break in the 11th before wrapping up his victory with a 72.

O'Sullivan now faces either Ryan Day or Neil Robertson in round two.

The scoreline was more emphatic than their last meeting, the SAGA Insurance Masters final where O'Sullivan triumphed 10-3, this time he shaved a frame off with a 10-2 demolition.

The victor revealed he did not feel sorry for friend Ding following the first-round trouncing.

"There is no place for feeling sorry for anyone, but I am a big fan of Ding, he is a friend of mine," the two-time world champion told BBC.

"I just hope that match stands him in good stead for next year."

"I was up for it from the beginning. I got off to a good start, " he added.

Despite the defeat Ding said the experience he gained on his first appearance at the Crucible was invaluable.

"I tried 100 per cent but Ronnie played very well. The match I lost at Wembley did not affect me," the 20-year-old said.

"The Crucible is the best arena I have ever played in. I'm still very young and I hope I will have a lot more chances to win here."

Teenage Judd Trump was the other rising star falling on Monday after a 10-6 defeat to 2005 world champion Shaun Murphy. But the 17-year-old made Murphy work hard to book his place in the second round.

Murphy led 5-4 going into the second session but Trump bounced back, clinching the 10th and making an 85 break to take the lead. But experience paid off for the 24-year-old from Rotherham as he won the last five frames to seal the victory and set up a clash with John Parrott.

Qualifier Fergal O'Brien also clinched a berth in the second round with a tense 10-9 win over world number 12 Barry Hawkins.

While Mark Allen proved he will be no pushover on his Crucible debut after taking a 6-3 lead in his first-round match against 1997 world champion Ken Doherty, 2004 UK champion Stephen Maguire enjoyed a comfortable 7-2 lead over Joe Perry going to their second session
