I wasn't sure where to put this as we don't have historic threads as, well, Brits don't usually qualify!
As folks know, the WTA Finals in Saudi got transferred to Indian Wells this year as a one off venue, next month.
From 2027 onwards, Charlotte will be the venue for three years, indoor at the Spectrum, where Charlotte plays NBA. Due to the basketball, the event will shrink to a 5 day event. The WTA are consulting with players on the format from next year as the current round robin would make it 4 singles and 4 doubles each of 5 days with players playing everyday. Clearly that won't work.
Whether it will slim down to a smaller field (6 singles?) or maybe they will go for a straight knockout? maybe a singles field of 12 in a knockout over 5 days and reduce doubles to say a 6 pair field?
anyway, the format will stay as it has been for this season in IW but change almost certainly from next.
