Mark Williams's 145 is the highest break so far and, obviously, a very good marker for the £1,000 prize for the best effort of the non-televised phase.
He leads Tom Ford 7-2 and now looks very good to qualify.
So too do Judd Trump and Liang Wenbo who hold 6-3 leads over Stephen Lee and Dave Harold respectively.
The other two matches are much tighter, though. Fergal O'Brien can't quite shake off Jamie Burnett while Anthony Hamilton is making things very tough for Ricky Walden.
Can't see either of these matches finishing early somehow.
