October 8-9, 2019, the Jewish holy day of Yom Kippur, marked a unique moment in the history of baseball and American Judaism. Three Major League post-season games began between sundown Tuesday and sundown Wednesday. One team in each game featured a Jewish player as a star or significant contributor. Each Jewish player appeared in the game. Each team lost. One journalist labeled this result the "Koufax Curse" -- the curse of the Jewish player who plays on Yom Kippur, rather than following in the footsteps of Hall-of-Fame pitcher Sandy Koufax, who did not pitch Game One of the 1965 World Series when it fell on the holy day.
This paper empirically tests the Koufax Curse. Looking at 18 Jewish Major Leaguers since 1966 (the year after Koufax's career-defining game), the paper charts how the players and their teams performed in games played during any part of Yom Kippur. It also examines statistics for Rod Carew, the Hall-of-Famer who is not Jewish but enjoys a unique familial and cultural connection to Judaism. From this, we can measure whether players or teams are haunted by the Koufax Curse. And whether Yom Kippur 5780 was an anomaly or reflects a broader trend.
