Caroline Wozniacki says Sascha Bajin will be a hitting partner and assistant coach.
Bajin, who was Serena Williams' longtime hitting partner and most recently worked with Victoria Azarenka, attended his first event with Wozniacki a week ago in Doha, where she reached the final.
Wozniacki said he would help her father and coach, Piotr, in addition to practicing with her.
"He looks at the matches, too,” she told the WTA website. “He scouts, and they talk a lot [about] what they feel I can improve on, and things like that. He comes with inputs and practices. He's definitely a hitter—plus. Assistant coach, I guess.”
