Coming into the clay-court season with few tournaments played from the first quarter of the season, Bacsinszky struggled to go deep in different events including a loss to CiCi Bellis at Rabat as the defending champion; a second round loss at Madrid to Kiki Bertens, and a loss to Karolína Plíšková in the third round of Rome. The Swiss however did upset the reigning French Open champion Garbiñe Muguruza in first round of Madrid, her first top-10 win of the season and first win against the Spaniard.
