Raducanu will face Greek 17th seed Sakkari in the early hours of Friday morning UK time, bidding to become the first British woman to reach a grand slam final since Virginia Wade won Wimbledon in 1977.
Sakkari is currently ranked 132 places above Raducanu, although that will change following the 18-year-old’s stunning run to the last four which will lift her to the cusp of the top 50.
At 26, Sakkari is an experienced campaigner but, like Raducanu, she will be looking for a place in her first grand slam final
“She’s a new player on tour so I don’t know much about her,” Sakkari said following her 6-4 6-4 quarter-final win over Karolina Pliskova.
“Obviously she’s having the tournament of her life. She deserves to be here. She has won all these matches.
“But I wouldn’t call myself the favourite. I think we all have equal chances of winning the semi-finals and then winning the title. I would give 25 per cent to each starting tomorrow, then 50 to the two finalists.
“We are all here for a reason. We’re all playing well. It was not like we had five walkovers. I’m excited to play a second semi-final this year.”
Raducanu continued her remarkable maiden overseas grand slam campaign with a 6-3 6-4 win over 11th seed Belinda Bencic.
In what has become the tournament of the teenagers, Canada’s Leylah Fernandez, who turned 19 on Monday, faces second seed Aryna Sabalenka – herself only 23 – in the first semi-final.
However, Sakkari said: “For sure I’m not old. I think I’m the best age of my career. I’m more mature than before.
“As I said many times, I think every single player has a different timing of breaking through. Now it’s probably my time at the age of 26.
“I came in late in the tour. I was not a good junior. I was not a star when I was 18 or 19 years old. I had to work and sacrifice a lot from my life.
“But it’s now paying off and I’m very happy that at the age of 26 I can actually achieve these results.”
