Watson says [against Halep] she will not abandon her new attacking strategy to accommodate the rise in class. “Definitely not,” she said. “If anything, I’ll try and be more aggressive against a player like that, so solid, so high up in the rankings, doing so well. You’re not going to get free points. I’m not going to hope for her to miss, because she’s not going to miss.” Source
So, either expect Heather to make tons of errors or make tons of winning shots! I'm confident Simona will come through just fine, something like 6-4 6-3.
