The first two semi finalists have been decided at the ASB Tennis Classic in Auckland.
The defending champion and top seed Coco Gauff is through to the final four after a straight sets win over France’s Vavara Gracheva.
Gauff was untroubled in advancing 6-1, 6-1 and is still yet to drop a set at the tournament.
She will play fourth seed and compatriot Emma Navaro for a place in the final.
Navaro also won her quarter final in straight sets, beating Croatia’s Petra Martic 6-4, 6-3.
