Radwańska made it three three-set victories in a row over Mona Barthel to make a winning start to her Qatar Open campaign. She ultimately needed 10 match points, but avoided the tiebreak and finally closed out the match after two hours and 26 minutes. "I’d rather not talk about those ten match points!" Radwańska joked. "The important thing is I won the tenth one". In the second round, Radwańska lost to the eventual champion Petra Kvitová in three sets. At Dubai, Radwańska lost to eventual finalist Daria Kasatkina in the opening round. Her next tournament was the Indian Wells Open where she received a bye into the second round. There, she lost to the eventual champion Naomi Osaka, who defeated unseeded Maria Sharapova in her opening match.
