History
2015: Top 100 debut, suspension due to doping
On 6 April 2015, she made her top 100 debut in the singles rankings.
On 27 May 2015, the International Tennis Federation announced that Kozlova has been found to have committed an anti-doping rule violation. She was found positive to a doping substance after taking a stimulant, dimethylbutylamine. Kozlova's suspension was reduced to six months starting from 15 February to 15 August 2015.
2018: First top-5 win
At the French Open, Kozlova became the second player to defeat a defending champion in the first round of the French Open, after a straight sets victory over 2017 champion Jeļena Ostapenko. Ostapenko was the first Roland Garros defending champion to lose in the first round since 2004 winner Anastasia Myskina dropped her opening match to María Sánchez Lorenzo in 2005.
2022: Back to top 125
At the Poland Open, she reached the semifinals as a qualifier where she lost to Ana Bogdan. As a result, she moved 56 positions up in the rankings to world No. 134, on 1 August 2022. She reached world No. 124 on 26 September 2022, the highest ranking for the season. At the Emilia-Romagna Open in Parma, she qualified into the main draw where she was defeated by world No. 7 and top seed, Maria Sakkari.
2023: Australian Open third round
She defeated Kamilla Rakhimova and Caty McNally to reach the third round of a Grand Slam tournament for the first time in her career.
