Ronnie O'Sullivan into semi-finals after beating Stuart Bingham at Crucible

Defending champion Ronnie O'Sullivan has beaten Stuart Bingham 13-4 to move into the semi-finals of the World Snooker Championship.

O'Sullivan, 7-1 ahead overnight, won the opening five frames of the second session and looked on course to claim the biggest Crucible quarter-final win.

After Bingham forced a final session, O'Sullivan took the first frame of the evening to win.

O'Sullivan will meet Judd Trump after his 13-12 victory over Shaun Murphy.

Meanwhile, Barry Hawkins beat Ding Junhui 13-7 in another quarter-final to reach the last four for the first time.

O'Sullivan misses out on record

If O'Sullivan had won 13-1 it would have been the biggest ever quarter-final win at the Crucible.

There have been two quarter-final matches that ended in 13-2 wins: Kirk Stevens's win against Ray Reardon in 1984 and Stephen Maguire's thrashing of Stephen Hendry last year.

The biggest ever winning margin came in the 1989 final when Steve Davis beat John Parrott 18-3.

Four-time world champion O'Sullivan, playing in his first major tournament after taking time away from the sport following last year's world title victory, had a chance to make some Crucible history.

No player had won a quarter-final by a 13-1 margin and O'Sullivan was on course to do so until Bingham claimed the sixth frame of the session.

O'Sullivan also had an opportunity to seal the victory without the need of a third session, but missed a frame-winning black when 39 points clear before Bingham made a clearance to win the last frame on the final ball.

But O'Sullivan quickly sealed the victory, winning the first frame of the evening's session.

World number eight Bingham had performed badly earlier in the session with his mistakes being punished.

O'Sullivan made only one break of more than 50 in the first four frames of the day before he compiled a score of 104 to move one away from victory.

However, Premier League champion Bingham rallied to ensure a third and final session.
