Shaun Murphy missed out on his desired whitewash but still cruised into the second round of the World Championship with a 10-1 win over Marcus Campbell.
The world number six resumed at 9-0 after a crushing opening session and had to fight for two more frames on Sunday after Campbell's stirring 62.
A 61 from Murphy, the 2005 champion, proved enough to see him over the line.
Andrew Pagett's debut was ended with a 10-7 defeat by Jamie Cope, while Ding Junhui leads Jamie Burnett 8-1.
The second day of the championship welcomed back Welshman Pagett, ranked 80, who had to overcome a 5-4 deficit against Stoke's Cope.
Pagett had secured a starting spot in his first major event by winning four qualifying matches and needed a strong start on Sunday to give his legion of Welsh fans hope of a big shock.
Losing the first two frames on Sunday did not help his cause, and despite a nervy Cope doing his best to prolong the encounter, it was the 'Shotgun' who edged through.
In the 18th frame Pagett was 10 points behind on the final red and snookered but though he escaped superbly he left the red over the centre pocket.
Cope potted it but broke down and Pagett looked to have seized his chance, needing just the pink to make it 9-8.
But as he lined up to play the shot, he was distracted by the light from the adjacent table being switched off, and after he regrouped he missed the pot.
Cope prevailed in the subsequent safety exchange and held position for the decisive black.
Meanwhile, Murphy looks in red-hot form and is one of the favourites to claim another world title, six years after his first, and did not disappoint with a convincing display in his opening match.
The damage was done in Saturday's first session when the Sale-based 28-year-old racked up a break of 100 and added three runs in the 90s.
It left Campbell, the 38-year-old from Dumbarton, who made the last eight in this year's PTC Grand Finals, facing the prospect of becoming the second player to be on the wrong end of a 10-0 defeat.
John Parrott recorded a whitewash 19 years ago with a first-round destruction of Eddie Charlton.
Campbell admitted he knew there was "no chance" of a comeback but felt satisfaction of at least making a fight of it.
The Scot knocked in a battling 62 break to secure Sunday's opening frame, helped by a fluked red at the end.
Campbell said: "I had felt good at 4-0 but he put me under so much pressure. The Crucible is a special place but it's made to make you feel uncomfortable."
Murphy, who next plays Ronnie O'Sullivan or Dominic Dale, said: "I put myself under pressure looking for the whitewash. I never had a chance in the opening frame."
And having played a monumental 108 matches on the Tour - the most out of all the players, he added: "I feel as sharp as anybody. I'm in good form and can't wait for the rest of the tournament. I've been practising hard and feel like my game is coming together at the right time."
