Emma Raducanu says it is a "weird feeling" to have reached the US Open semi-finals and be one of the last few remaining players in the locker room.
The 18-year-old Briton continues her dream run when she meets Greek 17th seed Maria Sakkari on Thursday.
The pair play on Arthur Ashe Stadium in New York at about 21:00 local time (02:00 BST, Friday).
"I didn't think I'd be here. But now I am, I'm so excited to get out there," said Raducanu.
Raducanu has exceeded expectations in her first overseas Grand Slam - and only her fourth tour-level event - by becoming the first qualifier to reach the US Open last four.
