I picked Monica Puig at (-190) and she demolished Tatjana Maria 6-1 6-1. I have been doing well on these early round matches looking for the top players who are on a run paired against weaker opponents who are on a losing streak when the odds are < -200.
As we get further into the clay season things are stabilizing as the top players are getting their footing on clay and thus the upsets are decreasing.
