Ronnie O’Sullivan let slip a 3-0 lead as he lost 4-3 to Mark Davis in the second round of the Coral Welsh Open in Cardiff.
On a day of shocks at the Motorpoint Arena, O’Sullivan joined Neil Robertson, Shaun Murphy and Marco Fu as casualties in the last 64 of the world ranking event.
O’Sullivan had been seeking to win his fifth Welsh Open title and defend the crown he captured last year. But he lost focus after winning the first three frames, allowing world number 31 Davis to take advantage and set up a third round meeting with Fergal O’Brien.
Five -time World Champion O’Sullivan looked in full control when he knocked in breaks of 97 and 74 to go 2-0 ahead, then dominated the third frame. But Davis launched his fight back with a run of 65 then got the better of a scrappy fifth frame, O’Sullivan crucially missing the final green to a centre pocket. Davis kept his momentum going and fired breaks of 81 and 64 to take the last two frames.
