Video - Century blasts past Ebdon
World number one Ronnie O'Sullivan moved through to the semi-finals of the Masters at Wembley after a 6-3 victory against his old adversary Peter Ebdon.
O'Sullivan recorded a clearance of 92 in the opening frame and stormed into a 4-0 lead at the interval.
Despite a fight back by Ebdon, who took three of the next four frames, a 106 break sealed the win for O'Sullivan.
The Englishman will meet Welshman Mark Williams in the semi-finals after he defeated Shaun Murphy 6-4.
Murphy won the first frame but the 2005 world champion was soon pegged back, with a break of 76 enabling Williams to level the match.
Williams went 2-1 up and then won three of the next four frames to assert his control.
The long game I've got at the moment is just laughable
However, Murphy reduced the deficit to two frames at 5-3 with an excellent break of 57, and then took the ninth frame with a break of 97.
Williams opened the tenth with a break of 63 before stalling, and he then missed a difficult red which kept Murphy in the match.
Murphy cut the gap to 31 before missing a red, but Williams could only take limited advantage as he snookered himself on the yellow.
The players traded safeties until Williams made the decisive breakthrough to advance.
Williams will face an O'Sullivan in mixed form.
Breaks of 92, 53 and 74 in the opening three frames helped O'Sullivan seize control of the match, but after the Essex man secured a 4-0 lead, Ebdon clawed his way into the match in fortuitous circumstances.
The 2002 world champion fluked a red when the ball rattled the jaws of the yellow pocket, travelled the length of the table and then rebounded back again before dropping into its intended target.
That helped him take the fifth frame and he reduced the deficit to two by edging a tight sixth, despite a 54 break from his opponent.
O'Sullivan moved into a 5-2 lead only to be pegged back again, but his century assured victory although he remained
After a mixed display O'Sullivan was far from happy with his performance.
"Peter could have won the game quite easily," he told BBC Sport.
"I would rather be 3-0 down and hit a bit of momentum than be 3-0 up and feel like I'm stalling when I come to the table.
"Most of the time I'm missing a lot of shots and it was difficult to find confidence out there.
"The long game I've got at the moment is just laughable."
