If players are continually withdrawing from Premier Mandatory events less than 2 weeks before a slam, perhaps the calendar needs reshuffling so that these events finish 2 weeks before? Of course some of these players need to get a grip and actually have a thirst to win these events before a slam too.
I get the impression the Osaka camp are being extremely cautious as they probably imagine she has a good shot at another slam or two this year, but also she could do with playing in form players like Bertens on clay before the French begins, surely?
For me, it seems too many players are playing light schedules as if they're legend level like SW, VW etc - they don't have the experience advantage of these kinds of players when encountering an in form player who has been playing a fair amount more than they have.
