Osaka announced she will no longer be working with Sascha Bajin on Monday. Bajin confirmed the news, thanking Osaka for the opportunity.

The move came as a surprise. Osaka wasn’t just coming off a win, she had also just become the WTA World No. 1.

Oddly, this has become a common trend within tennis. The three women to win the most recent grand slam events are no longer working with their coaches.

Osaka won both the US Open and Australian Open and has now parted ways with Bajin. Angelique Kerber, who won at Wimbledon in 2018, parted ways with her coach, Wim Fissette. And reigning French Open winner Simona Halep is no longer working with coach Darren Cahill, who helped her reach No. 1 status before Osaka. Cahill said he split with Halep to spend more time with his family.

It’s not just those three, though. Sloane Stephens and Venus Williams also changed coaches in 2018, according to the New York Times.

Neither Bajin nor Osaka has revealed the reason for the split. Osaka has yet to name a new coach.
