"Always staying in the hunt and never letting it slide away. That certainly doesn"t guarantee results, doesn"t guarantee success. It guarantees you give yourself the best chance to do what you do and to figure it out and to find your way." Barty will face Paula Badosa in the semifinals. The Spaniard upended No. 8 seed Belinda Bencic 6-4, 7-5 in one hour, 49 minutes. Bencic committed 29 unforced errors in losing to Badosa for the second consecutive time.

"Because sometimes these matches are a little bit tricky when you played her two, three weeks ago and you think in your head that you have that opportunity to make a semifinals. I was quite nervous, but I"m quite happy that I could control all the nerves and I could play my game quite good."
