After less than a year together, Dayana Yastremska has decided to end her coaching partnership with Sascha Bajin. One of the highest profile hires in this past offseason, the Ukrainian reached just one final under his watch and lost in the second round of the U.S. Open to Madison Brengle.

Bajin had worked with Kristina Mladenovic before joining forces with Yastremska and he also coached Naomi Osaka to two major titles at the 2018 US Open and 2019 Australian Open. He rose to prominence as the hitting partner of Serena Williams.

In a statement released on her social media, the 20-year old said "I would like to announce that after the US Open, I decided to stop my cooperation with Sascha Bajin. I want to thank him for everything and wish him a good luck. It was a good experience for me".

Hours later, Bajin took to Instagram to give his own thoughts on the split: "I want to believe we both wanted the same thing just our paths of getting there are different. I sure learned a lot from you too and want to thank the whole family for trusting me in the first place.

"I'm also sure that not seeing each other and practicing for six months was feeding more into separating rather than bringing us all closer as a team. I want to thank Marino [Basic, Yastremska's trainer] who I hope will have some more players with me to train in the future... Things happen for a reason and I wish nothing but the best to Dayana and her new team."
