Dmitry Tursunov coached Anett Kontaveit to the world No. 2 ranking.
The 26-year-old Estonian will move forward without Tursunov as her coach because of travel-restrictions her Russian coach faces.

Kontaveit announced the split on social media, writing: "we have mutually agreed to go our separate ways."
"I’d like to thank Dimitry Tursunov on a very successful time together," Kontaveit posted. "Along the way we enjoyed a number of big wins. Moving forward, we have mutually agreed to go our separate ways. I wish him nothing but the best!"
In an interview with Estonian website ERR, Kontaveit said the split was due to Tursunov's travel limitations.
"The reason we made this decision is that he has a Russian passport and therefore it is very difficult for us to get visas to travel," Kontaveit told ERR. "Even if we wanted to, he wouldn't be able to accompany me to many tournaments and, for now, I think I still need someone by my side who doesn't pose me with these kinds of practical problems."
Kontaveit produced a breakout 2021 season winning four titles: Cleveland, Ostrava, Moscow, Cluj-Napoca.
Last February, a spirited Kontaveit survived a seven-game slide and roared back from a 2-5 deficit in the decider streaking through the final five games in a wild 5-7, 7-6(4), 7-5 comeback triumph over Maria Sakkari in the St. Petersburg Ladies Trophy final.
Solidifying her status as tennis’ true indoor queen, Kontaveit scored her 20th consecutive victory indoors.
Kontaveit, who is at her best on hard courts, struggled recently on clay. The aggressive baseliner suffered successive opening-round losses in Rome and Roland Garros.
