In the women's 2 semifinals we have 2 big favorites based on Barty's and Halep's odds.
Barty's 1.28 against Cain you mean it's not worth it. Barty may be at # 1 and playing in her home country, but Kenin isn't that bad. She has made headway at # 11 and will be at # 8 if she wins even over Osaka, Quitova. Most important, though, is that the points have not won their fireworks in big tournaments but with constant stability. I will loose a 3,55 double though I give Barty a win because the performance is excellent and certainly much better based on Kenyan's chances of winning.
In the other semifinal I won't bet anything. Halep's 1,57 is probably a fair performance as the Romanian has been the most consistent high-level player in the last 2-3 years. But Mugurutha has the experience and looks to get back to the high she was two years ago when she reached # 2. I haven't seen her play this year though so I have a clearer picture so I can trust her at 1. However if I found Halep 2.35+ I would have bet it well
