The 22-year-old has been battling more injury issues having withdrawn from the ASB Classic in Auckland due to a back problem.
But she has declared herself fit to play and will take on No26 seed Alexandrova.
“I’ve been feeling good,” Raducanu said ahead of her first-round match. “I think the last 10 days I’ve had a positive block of training.
“Coming back on the court, adapting to the conditions here, has been good for me. Now I feel good and I feel ready to give it my best here.
“It’s a tricky draw, of course. Being unseeded, you can play any top opponent. She’s a player with a lot of experience. I guess I’m coming in with the underdog mentality. She’s been in this situation many more times than I have.”
