Defending women's champion Nour El Sherbini shattered home American dreams at the Professional Squash Association World Championships, as today's four semi-finals were all won by Egyptian players.
The top seed, who is aiming for a fifth world title in a sixth editions, defeated home player Amanda Sobhy 11-3, 11-5, 11-5 at the University of Chicago's Cathedral Hall.
Sobhy had become the first American player to reach the last four of the World Championships but was beaten in 25 minutes.
"I took a bit of an advantage of the crowd supporting her, so it put pressure on her more than me," said El Sherbini, who is now the first woman to make six World Championship finals in a row.
"I knew that everyone would be behind her, I wanted to be relaxed and calm and focus on my game plan.
"Thankfully, I had my dad here, he is the main support for me today and all the crowd I needed today, he's the main reason for my win."
El Sherbini is yet to drop a game in Chicago and will meet compatriot and second seed Nouran Gohar in the final.
She enjoyed a similarly comfortable last four clash, beating France's third seed Camille Serme 11-8, 11-4, 11-3.
In the men's tournament, the final will also be between the top two seeds as Ali Farag and Mohamed ElShorbagy made it through.
Second seed ElShorbagy is now guaranteed to take the world number one spot away from Farag, regardless of the outcome of the final.
The 2017 world champion defeated the runner-up in the last final, New Zealand's fourth seed Paul Coll, 11-5, 11-3, 4-11, 11-8.
Top seed Farag, who won the world title in Chicago in 2018-2019, won a titanic battle against Egypt's third seed and reigning champion Tarek Momen, 10-12, 11-5, 12-10, 5-11, 11-8.
"It very rarely happens to me against any other player, but against Tarek when you get into his pace, you lose it," said Farag, who had to be treated for a knee problem midway through the match.
"Maybe I'm not very proud with the way I threw it away and then the knee thing happened and I was all over the place.
"I don't know how I won that fifth, I don't know what happened.
"I just said 'Ali, find a way.'"
Both finals are tomorrow.
