Mel wins. Well done Katie for keeping pace; in some ways, this is the worst result - if Mel can't beat Katie convincingly on her best surface, we can't hold out too much hope against Zheng. If Katie had landed some of her 13 DFs she would surely have won too...
A good win for Naomi earlier today and she needs to make the most of the grass court season and pick up plenty of points.
Probably for the best that Mel beat Katie given that she's defending a lot of points and probably has a better chance of getting through the next round, but that didn't sound like a pretty match and it seems they tried to out-choke each other.
