World No.1 Osaka in shock split with coach Bajin
World number one Naomi Osaka has split from her coach Sascha Bajin just weeks after winning the Australian Open to complete back-to-back grand slam victories. Osaka had worked with the German for just over a year. No reason was given for the decision to part ways. She linked up with Bajin in late 2017 and enjoyed a breakthrough year, climbing from 72 in the world to the top of the women’s rankings.
