So after four results at the Ladbrokes Mobile Masters, four top eight seeds are out.
Ding Junhui potted a great green using the rest to shake off a below par Mark Williams 6-4 and Graeme Dott was very strong in seeing off John Higgins by the same score.
This afternoon Ronnie O’Sullivan enters the Wembley fray. This is a tournament that inspires O’Sullivan. He has won the title four times and been in nine finals.
But Mark Allen beat him at the Crucible two years ago and the feisty Northern Irishman tends to play well against the top players.
Last year Allen sent John Higgins packing in the first round but he knows he will have to make the most of every chance that comes his way to threaten an upset today.
One thing to look out for: O’Sullivan is poised on 49 Masters centuries. In this regard he is ahead of Stephen Hendry, who has made 43 in the tournament.
Tonight it’s Stephen Maguire against Marco Fu, who has actually dropped out of the elite top 16 but was in it when the Masters seedings were done.
Maguire is capable of top drawer performances but that little bit of inconsistency means that you never really know when they are going to come along.
Fu is a difficult player to play against when he’s in form. He plays to a solid rhythm and it’s hard to knock him out of it.
The decisive factor could be whether Maguire can keep a lid on any frustrations and just concentrate on the job in hand.
We’ve had a few shocks at Wembley Arena this week but I think this is in part because of recent changes in the game.
The top players now play each other so often that some of the fear factor has gone. More players are in form and more fancy their chances.
All of which makes it interesting, but hard to predict.
