Mark Williams through to last 16 in Sheffield

Mark Williams produced the highest break of the tournament so far as he eased into the second round of the Betfred World Championship in Sheffield.

Williams, twice a winner of the event at The Crucible, compiled a total clearance of 140 on his way to a 10-5 win over Jimmy Robertson.

The 43-year-old Welshman held a 7-2 lead after the first session, but saw Robertson threaten to stage a comeback by winning a scrappy opening frame and then stealing the next with a 55 clearance after Williams had been first in with a break of 54.

However, Robertson then paid the price for missing a tough opening red along the cushion in frame 12 and Williams took full advantage with a total clearance, before moving within a frame of victory with a break of 100 in the next.

Robertson kept his hopes alive by winning the 14th frame but Williams was not to be denied and secured the victory to set up a last-16 clash with either Neil Robertson or Robert Milkins.

Milkins takes a 6-3 lead over former world champion Robertson into their decisive second session on Wednesday afternoon.
