That's a career best win by ranking for Isabelle Does anyone know if she used to represent Switzerland at some point (there are some indications that she did but it's not entirely clear), and if so, when she switched?
It'll be interesting to see how long they persist with interleaving the W15 and the W75, but maybe all they'll do is play R1 so that at least the players there get a chance to pick up a ranking point.
