Couldn't watch Miki's debut, but how heartening to see her open with a nice win. From the Q-round scorelines, Barthel appears to be playing far above her ranking.
Mostly, it's a wonderful thing that Miki opens a season with a main draw WTA victory. In 2017! Ostapenko is obviously very dangerous (reminds me of Bencic, when Bencic could still play) but she can be overpowered if the points are kept short. Hope Miki can hang in there.
