Mark Selby staged a remarkable comeback to beat Stuart Bingham and reach the quarter-finals of the Masters.

The world number one looked to be heading out after losing five frames in a row to trail 5-1 at Alexandra Palace.

But he battled back to force a decider and, after Bingham missed a crucial blue, Selby wrapped up a 6-5 win.

Selby will meet Mark Williams, who earlier had completed a similar recovery, from 4-1 down, to beat fellow Welshman Matthew Stevens 6-4.

The world number seven, a two-time winner of the title, trailed Stevens 3-0 and 4-1 in an error-strewn contest.
