Simona Halep is in the final against Caroline Wozniacki, knocking out Angelique Kerber.
The No 1 seed raced into a 5-0 lead in just 14 minutes of Thursday’s semi-final.
But the 2016 champion hit back from a break down in the second to level the tie.
Both players spurned opportunities to serve for the match in a helter-skelter final set before the Romanian broke to claim a 9-7 victory.
