Three Anglo-Welsh battles are to be staged on Sunday at the Crucible with the highlight seeing former champion Ronnie O'Sullivan and Mark Williams resuming their titanic battle.
Four players who pulled off superb results in their opening matches now go in search of coveted Quarter-Final places in snooker's flagship event.
Neil Robertson, Stephen Maguire, Stephen Hendry and Ryan have all booked their place in the last eight but which four other players will join them?
Sunday's morning session sees two rising stars collide as Welsh wonderkid Jamie Jones takes on Cheshire's Andrew Higginson in a potential classic.
Jones defeated 2005 champion Shaun Murphy with a fine display of potting in the first round while Higginson dumped out this season's form player - Stephen Lee.
For both players, the opportunity to reach a maiden Crucible Quarter-Final present the biggest match of their careers to date and both will give their all over three nerve racking sessions.
Another Welshman Matthew Stevens is up against in-form Shootout winner Barry Hawkins as the duo also contest the opening two sessions.
Stevens breezed past Marco Fu in his opener, while Hawkins ended the hopes of world number one Mark Selby. Both will be full of confidence going into this one and are capable of regular high breaks.
Four of the world's most skillful cueists are in action in the afternoon in a potentially explosive second session of snooker.
Ronnie O'Sullivan showcased a determined attitude during Saturday's thrilling opening session against outspoken Welshman Mark Williams and will be hoping to extend his advantage going into the third and final day.
Williams led 3-2, but the Rocket produced a mixture of fine break-building (including a run of 95) as well as effective tactical play to forge a 5-3 lead.
Pre-tournament favourite Judd Trump looks to overturn a two-frame deficit against the resurgent Ali Carter who came out on top in the epic opening exchanges on Saturday night.
Former finalist Carter has seemingly found a second wind and held his nerve superbly in leading the young sensation 5-3 following a series of dramatic safety battles and outrageous shot selections.
The action gets underway at 10am GMT, with all matches being streamed live over the best of 25 frames over three seperate sessions from the Crucible Theatre, Sheffield.
