Defending champion Ronnie O'Sullivan beat fellow Englishman 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 a record Crucible quarter-final victory.

Bingham won the next three to force a final session, but O'Sullivan sealed victory by winning the first frame.

O'Sullivan will next meet Judd Trump, who beat Shaun Murphy 13-13 in an epic.

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

He will meet England's Ricky Walden, who defeated Wales' Michael White 13-6.
