Halep 6-3 6-2 Pliskova
Simona Halep, speaking to Sam Smith after her victory: "It's nice to be in the semis. I was in the semis in the juniors in 2008. It's nice to play on this amazing court in front of everyone. It wasn't my best start but I knew I had to restart and move better which I did in the end. It will be a different challenge against Angelique Kerber. I have to be ready, be calm and try to dominate the match and finish the points. I'm not thinking about the result. I just want to play my best."
