The Whirlwind is on a ten-match winning streak in the tournament.
Jimmy White beat Darren Morgan 4-1 to reach the World Seniors Championship semi-finals on Saturday at the Crucible Theatre in Sheffield.
The reigning champion is on course for a third world seniors title on the trot and a fourth overall after overcoming the Welshman in a match that was closer than the scoreline suggests.
After losing the opening frame Morgan equalised with a terrific tournament-high break of 134, and the 2011 world seniors champion looked set to take the lead in the third frame only for White to snatch it by a point on the final black.
The latter subsequently stole a close fourth frame in similar fashion and duly wrapped up the victory in the next – ending the contest with a pot success rate of almost 91%.
White will face Igor Figueiredo in the World Seniors Championship semi-finals after the Brazilian outplayed Stephen Hendry earlier in the day to secure another 4-1 success.
Hendry, whose wait for a maiden title at this level goes on, started brightly with a contribution of 76, but Figueiredo dominated from then on and compiled breaks of 100, 68, and 61 to oust the seven-time world champion.
On the other side of the draw, David Lilley ended the hopes of last year’s runner-up Ken Doherty with a nail-biting 4-3 victory.
Doherty fought back from behind to force a deciding frame, but Lilley held his nerve in the last moments and made a 69 to advance to the last four where he’ll face Patrick Wallace.
The Northern Irishman, the last remaining amateur in the draw who doesn’t still compete on the Main Tour, recorded a 4-2 triumph against Barry Pinches.
The World Seniors Championship semi-finals take place on Sunday afternoon over the best of seven frames, with the nine-frame final scheduled for 7pm at the Crucible Theatre.
