The year 2015 was a major breakthrough for Anna. She won two WTA tournaments. In Katowice, she defeated Alize Cornet and Camila Giorgi. In Bucharest, she won with Sara Errani in a rematch. Sara defeated Anna in the previous tournament in Rio. Schmiedlova was awarded the “WTA Rising Star Of The Month” title. In October, the same year, she triumphed over US Open runner-up Roberta Vinci at the Huajin Securities WTA Elite Trophy Zhuhai. She reached a career-high ranking of world number 26.
2016 was a polar opposite. She opened the year with a loss at the Brisbane International where she failed to win with Varvara Lepchenko. At Apia International Sydney she was beaten in the second round by Mónica Puig. Daria Kasatkina upset Anna at the Australia Open in the first round. At the World Group II Cup, she eliminated Arina Rodionova and subsequently was defeated by Samantha Stosur. Later she suffered a series of 16 losses in tournament matches, mostly in straight sets. As a result, she dropped in singles ranking from position 26to to 227. Anna attributed the weak performance to high pressure. She had high expectations and the inability to satisfy her goals contributed to uneasy and nervous games. She admitted that if she could turn the time back, she would slow down and play more calmly. Despite these setbacks, she tries to see positive things. She had few good matches, against Murguruza in Roland Garros and Vinci in Rio de Janeiro.
After underwhelming 2016 she decided to take a vacation and replenish her energy. Together with her friend, Jana Cepelova, she visited Dubai. Jaroslaw Levinsky is no longer her coach. He was replaced by Michal Mertinak. Anna changed also her strength and conditioning coach. She decided to work with Tomas Mihalik, who is collaborating with Karolina Pliskova. Anna looks into 2017 with optimism.
