Where does Maddison Inglis go from here? I don't know.

I have noticed that the Sinner serve has been dropping a bit shorter than we're used to; I don't know if the legs are hurting, but it's more short than we're used to.

It's something to keep an eye on.

Iga Swiatek isn't worried about her first serve because her second serve is doing the trick right now.
