Ashleigh Barty, Aryna Sabalenka, Barbora Krejcikova and Karolina Pliskova have already qualified for the main event.
But Barty may not compete as she’s currently out injured, while Naomi Osaka – currently ranked eighth – may also miss out.
Ons Jabeur is set for a huge jump in the rankings after reaching the quarter-finals at Indian Wells.
Raducanu may miss out this year, but could be in contention next year when the WTA Finals return to China if she continues her meteoric rise.
