## Coaches

In August 2019, after Wimbledon Championships, Peterson started a collaboration with Swedish star coach Thomas Högstedt, who previously trained, among others, Maria Sharapova. Together with him, Peterson debuted in the top 50, and also won two WTA singles titles. After six months, in February 2020, they split. She is currently coached by her father (Mart Peterson) and Bosse Eriksson.

## Playing style

Peterson is one of the most aggressive tennis players on tour. Her most significant shot is forehand, that she also stated in interview with Live Tennis Italy: "My best shot is the forehand and I try to play by always varying the shot and looking for new solutions." In another interview, Peterson's former coach Thomas Högstedt talked about his impression of Peterson: "Rebecca knows a lot about how she feels herself, other big players maybe more just see how they beat the opponent – if you win the first set then you put in extra gear and decide. It is easy to feel after you are nervous or tired, but the best do not think so much about how they themselves feel. They only think about how to mentally crack the opponent. It's something she needs to work on. I think that bit is very important." Speaking about her game, Hogstedt says: "She has an incredibly good forehand, plays a bit like a men's player with quite a lot of topspin... Very serious, incredibly well trained." Her dad, Mart Peterson, who has also been her coach for most of her career, says: "Hogstedt has helped my daughter a lot and made her tougher. It has been a lot of help. She has become tougher against herself and tougher against her opponents."
