What's interesting me is that if Jo is playing sparingly to the end of the year then she is points heavy from spring - Wimbledon with lots to defend. I guess she can mitigate some of this by doing better in the earlier on in the year tournaments but the points banked from the latter part of this year would've been helpful.
I was thinking along these lines. Obviously Jo has to decide her own schedule but to not enter tournaments where she could tot up some points will add the pressure on her shoulders next season. She had some very good luck as well as playing well in the clay court season and it is hard to see her replicating those results next year.
I'm not confident for her chances in the US Open but she's had decent season so fingers crossed will do better than I expect her to.
Kuznetsova beat Barty so Osaka remains WR 1, and US Open #1 seed, ahead of Barty, Pliskova and Halep in that order.
Keys beat Kenin so Jo will certainly be WR 16.
16th seed at the US Open, while bracketing her with a 17 to 24 seed for the L32, would bracket her with a 1 to 4 seed for the L16. I'd very happily though take L16 now for Jo and whoever that might bring ( a fair chance not one of these top 4 seeds ).
