Four-time champion John Higgins overcame a slow start to ease into the second round of the Betfred World Championship with a 10-6 victory over Martin Gould at the Crucible.
Higgins held a commanding 7-2 lead overnight in the best-of-19 clash but lost three of the first four frames as Londoner Gould took the score to 8-5.
But Higgins, the world number six, sent out a warning with the manner of his third-frame success, putting together a 127 break - the third highest of the tournament to date.
Gould averted defeat with an 80 in the 15th frame but could not prevent the inevitable as Higgins sealed his win at the next attempt.
In the morning's other match, world number 48 Stuart Carrington compiled century breaks in three successive frames and ended the session with a 5-4 lead over Liang Wenbo.
After splitting the first four frames in a slow start to proceedings, Carrington made his charge by stringing together 124, 101 and 107 between the fifth and seventh frames for a 5-2 scoreline.
Liang's best contribution had been a brilliant escape shot but he closed the gap to one by taking the last two frames, teeing up a tight finish for the evening's play.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
