Higgins described his opponent as “lethal” as O’Sullivan treated the Sheffield crowd to a potting masterclass, making five centuries and 12 more breaks over 50 as he recovered an early 3-0 deficit to take 17 of the last 25 frames.
The Rocket is into his eighth Crucible final, having won the title in 2001, 2004, 2008, 2012, 2013 and 2020; his only final defeat was against Mark Selby in 2014.
He will face Trump over a possible 35 frames on Sunday and Monday for the trophy and £500,000 top prize. The champion will also finish the season as world number one.
Victory would see O’Sullivan equal Stephen Hendry’s record of seven world titles which has stood since 1999, and raise his marvellous career to yet another high. O’Sullivan is set to play in his 61st ranking final and is aiming for his 39th ranking title, which would move him further clear of Hendry’s previous record of 36. He is on course for a 21st Triple Crown success as he has already won the Masters and UK Championship seven times apiece.
