I am so pleased for Ons- I think starting a family was the thing that was holding her back for a long time. Yes, she wanted to win big titles,and came so close, but it was coming at the expense of other things.
Players like Elena Svitolina and Belinda Bencic have shown that it's possible to come back after having a baby, and get back to a hgh level- if that's what she wants. She might not - her priorities may change.
I think today is the day the men's bit of Madrid starts properly (the women's draw already has) - but who knows 
I know both Berrettini and RBA are in action. Also, NuRafa, and Marin Cilic.
