When Ayami Sato takes the mound as the starting pitcher for the Los Angeles Queens on Saturday, it will be the culmination of a professional career that has spanned 16 years and three countries. The right-handed hurler is largely considered the best pitcher in the history of women’s baseball. She has the awards and experience to prove it, and now she’s taking on America when she makes her debut in the Women’s Professional Baseball League, the first pro women’s baseball league in the United States since the 1950s.
Even though most Americans tuning into the WPBL may not have heard of her, Sato’s resume speaks for itself. Sato’s fastball has been clocked at nearly 80mph and her curveball has a devastating spin rate that is higher than many Major League Baseball pitchers. As a member of the Japan National Team since 2010, Sato has won six gold medals. She is the only player in Women’s Baseball World Cup history to win three consecutive MVP awards. As a member of the now-defunct Japan’s Women’s Baseball League, Sato led the league in strikeouts in three of the last four seasons. And most recently, in 2024 she became the first woman to play pro baseball in Canada as a member of the Toronto Maple Leafs of the Intercounty Baseball League.
