Which top guns? She's been beating top guns all year. Sure she's not played Naomi but its not Bianca's fault Naomi is losing early in these last two tournaments. And not her fault Serena has been pulling out with injury.I just watched highlights with her and Kerber.
Prediction: once the tour gets used to her extreme moonballing she will have severe problems with keeping up with the top guns.
Her movement is also quite suspect.
Sloane Stephens won a US Open with less game than Andreescu. The WTA is ripe for the picking these days. If you can junkball and then show power, you can beat a lot of women.
