We have a MTO, no guesses for who that might be. Laura was stretching out various parts of her body during her doubles match last night, so it looks highly probable after losing 8 points in a row I think, it's going to be her.
In my perusal yesterday of Univeral Tennis Ratings which I mentioned re the men I noticed that Katy and Laura were level on 11.60, not actually brilliant for either as made them GB =11. But I'd say tieing in with not much between them.
Their previous matches this week and evident heat again today may be the telling factor in Katy's favour today.
