The top two seeds will contest the final of the GoodLife Open in Canada after Hungarian Mark Krajcsak and Australian Zac Alexander survived lengthy semi-final battles in the PSA World Tour Challenger 10 squash event in its seventh year at Goodlife Fitness in Ottawa.
Favourite Krajcsak ended Peter Creed's brave run, beating the unseeded Welshman 11-7, 11-5, 10-12, 12-10 in 57 minutes.
The win takes the 27-year-old from Budapest into the 13th Tour final of his career - but his first this year.
Alexander prevailed against third seed Andrew Wagih Shoukry "in a much-anticipated match which did not live up to expectation," according to tournament organiser Heather Wallace.
The Brisbane-born 22-year-old recovered from a game down to beat the Egyptian 5-11, 13-11, 13-11, 11-8 in 83 minutes.
The marathon triumph sees Alexander through to his second PSA Tour final of the year - but the 14th of his career.
