Harlow lost out in the final at Potters in 2006
Scottish qualifier Stewart Anderson will face former runner-up Greg Harlow in Sunday's final of the World Indoor Bowls Championships in Norfolk.
The 24-year-old Anderson prevented an all-England final by defeating 20th seed Nick Brett 8-2 11-8.
Harlow, seeded five, beat compatriot Rob Paxton, who came through the qualifiers with Anderson, 9-8 8-4.
Anderson said: "I can't believe I am in the final of a world championship. It is unbelievable."
He has already accounted for fellow Scot and five-time champion Alex Marshall, 15th seed Mark McMahon and 18th seed John Price on his way to the final at Potters in Great Yarmouth.
Stewart will be a force to be reckoned with tomorrow
Beaten semi-finalist Nick Brett
And the defeated Brett believes Anderson, the world junior champion from Cumnock, could be a surprise winner of the title.
"I did not settle and he was sensational," said the Englishman. "He will be a force to be reckoned with tomorrow."
Anderson eased through the first set and it looked all over after he moved 7-2 ahead in the second before Brett threatened a fightback.
The second semi-final was a more topsy-turvy affair, with Harlow scoring four at the opening end before falling 8-4 behind then coming back to clinch the first set.
It was the greater experience of the 2006 runner-up from Ely that told in an equally tense second set.
