Pironkova started the year ranked No. 50 and began the season at the Brisbane International where she lost her first-round match to seventh seed Carla Suárez Navarro. Then she returned to Sydney to play the Aipa International as the defending champion and once again had to go through qualifying, as she was not given a wildcard entry. At the time, Pironkova was ranked No. 67 and lost the points from her title. She beat eighth seed Flavia Pennetta in the first round in straight sets, then overcoming unseeded Madison Keys and Záhlavová-Strýcová both in straight sets, but then lost in the semifinals to second seed and eventual champion Petra Kvitová in a repeat of the 2014 semifinals. With this defeat, she ended her 14-match winning streak at the tournament.
