The Ukrainian has tremendous potential and Bajin has big-time experience. Dayana Yastremska has hired Sascha Bajin as her coach for 2020.

The 19-year-old World No.22 is coming off a banner season that saw her win two titles and claim 35 wins. The Ukrainian possesses jaw-dropping power and athleticism and has the potential to get much higher in the rankings with proper guidance. She was coached by Belgium’s Olivier Jeunehomme and worked at the Justine Henin Tennis Academy previously.

Yastremska and Jeunehomme announced their split after a productive season in late September.

Bajin has previously worked with Serena Williams as a hitting partner and coached Naomi Osaka to both of her Grand Slam titles. He finished this season as the coach of Kristina Mladenovic.

“I am extremely happy, and I am very excited to start our collaboration,” Yastremska wrote on Facebook. “I am confident that he can help me in achieving my ambitions. Super excited for the beginning of our preseason preparation and I am confident that everything works out!”
