In 1999, the Yankees and Red Sox faced each other for the first time in the ALCS. The Yankees were the defending World Series champions, while Boston had not appeared in the ALCS since 1990. The Yankees won Game 1 on a 10th-inning walk-off home run by Bernie Williams off Boston reliever Rod Beck. Intensity built up due to this historic, first-ever postseason meeting between the two longtime rivals. The Yankees would win the first two games at home with 7th-inning comebacks.
