Wozniacki will have another formidable task in the semifinals on Saturday against Petra Kvitova, who had an easier day in the office on Friday thanks to Julia Goerges retiring with a hip injury at 6-4, 2-1 for the Czech.
Oh, and if Wozniacki reaches the final, she'll be facing a very refreshed Garbine Muguruza (she got a walkover from Simona Halep in the semifinals).
"It must feel nice for her to be in the finals already. I wish I had a day off," Wozniacki said. "But it is what it is. Sometimes it happens. But I'm just going to go out there and fight and that's really it. I'm with the mindset that everything happens for a reason and you just go out there and try and do your best."
