Wilson looked fresh and focused as he took the opening frame of the day with a break of 73 to reduce the deficit to 10-8.
But O’Sullivan was also up for the challenge, and a series of costly errors from Wilson in the subsequent frames shifted the momentum firmly in favour of the 44-year-old.
Like Reardon. Like Davis...
SIX world titles for @ronnieo147! #ilovesnooker @Betfred pic.twitter.com/QpPjepaUcK— World Snooker Tour (@WeAreWST) August 16, 2020
In the evening session, O'Sullivan needed just one frame to claim his sixth world title, putting him on par with Steve Davis and Ray Reardon.
Both players were cheered into the arena for what promised to be one of the quickest final Crucible sessions on record.
And O’Sullivan threatened to complete the job in a blink of an eye when he got in first before a surprising missed black gave Wilson a chance.
Yet again, the underdog failed to make the most of his opportunity and let in O’Sullivan to sweep up with a break of 96 to wrap up an 18-8 win.
