The only reliable option to play on grass before Wimby was the next week's Roehampton G1 (and to use this week's SE on some other tournament), that's a tournament with some depth and maybe it would've helped her getting used to the surface. Plus a chance for some more points in that battle for the first place in the rankings. But she's no Bencic
However, I don't get why she's playing doubles in Montpellier. Perhaps she wants to adjust her net game or something.
