The Yankees and Astros first met in the postseason in the 2015 American League Wild Card game. The Bronx Bombers lost that game 3-0. Since then, the two have matched up twice more, once in the 2017 AL Championship Series, where the Yankees lost in seven games, and the Astros went on to win the World Series. The next was in the 2019 AL Championship Series again, and again, the Yankees lost, but this time in six games.
When the Astros cheating scandal was uncovered, the bad blood between these teams was taken to a new level.
