John Higgins survived a final-frame decider against Jack Lisowski to book his place in the World Championship semi-finals and seal an historic achievement for the fabled ‘Class of 92′.

After earlier wins for Ronnie O’Sullivan and Mark Williams, Higgins’ 13-12 success marks the first time the trio – who all turned professional 30 years ago – have reached the last four at the Crucible since 1999.
