Last Friday night in Kyoto was the final evening of the Japan Women's Baseball League's "Victoria Series Spring League", which is basically a nine game tournament between the three primary teams of the league (Aichi Dione, Kyoto Flora and Saitama Astraia). Friday night's game between Saitama and Kyoto (which was a home game for Saitama despite the game being played in Kyoto) went into extra innings tied at one. In the bottom of the eighth (JWBL games only go seven innings), Saitama's Mari Yamazaki came up to bat with one out and Haruna Tadano at first and proceeded to do something that had never been done before in the 10+ year history of the JWBL:
Yamazaki hit the first ever Sayonara home run in the history of the league to win the game for Saitama 3-1.
