This season was the breakthrough year for Dayana Yastremska. A career-high ranking and two title wins set the 19-year-old up for success next year. And now, she has a new coach to guide her.
Sascha Bajin, who fans may know as the coach of Naomi Osaka who propelled the Japanese player into two Grand Slams and world No. 1 status, is now the force behind Yastremska. Her previous coach was Olivier Jeunehomme, who is affiliated with the Justine Henin Tennis Academy where Yastremska trains.
