Widely considered the top female pitcher in baseball, the 35-year-old from Japan signed with the Maple Leafs in December to become the IBL’s first female player.
Sato helped Japan win five of its seven consecutive Women’s Baseball World Cup titles (2010, 2012, 2014, 2016, 2018), earning MVP honours in 2014, ’16 and ’18.
She pitched in the Japan Women’s Baseball League from 2013 until it suspended operations in 2021, leading the league in strikeouts in three of its last four seasons.
Toronto finished seventh in the IBL last season with a 17-25 record.
