John Higgins blamed the suffocating Crucible pressure for his poor performance despite battling his way into the second round of the World Snooker Championship with a 10-7 win over China's Tian Pengfei.

The four-time champion hit back from 7-4 behind to win six frames on the spin, belatedly finding his form in a match that twice went over its allotted schedule time by completing his victory with two consecutive centuries.

It may be the 45-year-old's 27th appearance at the Crucible but, despite his colossal experience, Higgins admitted the venue's weight of history was still impossible to ignore.

Higgins said: "It's this place that does it - I think I stopped breathing a few times out there. That's what it does to you - the pressure can be that intense.

"It was a poor game by me and I've dodged a bullet there big time because Tian had enough chances to beat me. I've brought him down to my level and it's a big relief."

McGill now faces the defending champion in round two

Higgins' compatriot Anthony McGill proved he had no Crucible hangover from his agonising semi-final defeat eight months ago as he cruised into the second round with a 10-5 win over Ricky Walden.

McGill's previous appearance at the famous venue culminated in one of the most remarkable passages of play in snooker history as he lost his last-four decider to Kyren Wilson in a frame with a total combined score of 186.

The 30-year-old Scot declined an invitation by Eurosport to appear in a special programme about the frame in the build-up to this year's tournament but insisted: "It didn't hit me hard at all, and I was over it five minutes afterwards.

"I was asked (to appear in the programme) but I didn't want to. I was over it, but that frame still cost me one hundred grand so I don't really want to sit down and talk about it fondly."

Resuming with a slender 5-4 advantage over his fellow former semi-finalist, McGill extended his lead with back-to-back breaks of 83 and 130 before a 98 from Walden reduced the deficit.

But McGill responded to close out the match with three frames in a row, including two more half-centuries, to set up a date with Ronnie O'Sullivan.

"I'll just try to play my own game," said McGill. "I don't think there's anyone in the game who's got the aura that Ronnie's got - he's the best ever and I'm really looking forward to it.

"I won't approach the match any differently. I can only play as well as I can play, and if the other guy is too good then that's fine."

Ding Junhui built a 5-4 overnight advantage over former champion Stuart Bingham, despite breaks of 131 and 129 helping Bingham establish a 3-1 lead.

Ding, the world number nine and runner-up at the Crucible to Mark Selby in 2016, produced clearances of 105 and 86 levelled the match, and nicked the ninth frame on a fluked final black.

Fourteenth seed Jack Lisowski fought back from 3-1 down to fashion a 5-4 overnight advantage over former finalist Ali Carter.
