On this week's episode of Beyond the Baseline, host Jon Wertheim talks with Sascha Bajin, current coach of Kristina Mladenovic and former coach of Naomi Osaka. After splitting from two-time Grand Slam champion Osaka in April, Bajin signed on with Mladenovic and he discusses the details of his coaching relationship with both players and the approach he takes in his role with different players.

Wertheim and Bajin also discuss whether he would consider coaching a men's player; how he handles information when switching between different players; what he has learned from some of his former clients, such as Serena Williams and more. Bajin also talks about his forthcoming book, Strengthen Your Mind, which will be published in Japanese in July and details how he transformed Osaka's mindset and gives insight into his years working with Serena.
