The Yankees began the postseason by defeating the Athletics in the 2018 American League Wild Card Game 7-2. They moved on to face the Boston Red Sox in the ALDS. This was the first time since the 2004 American League Championship Series that the two teams faced each other in the postseason. They fell short in 4 games, as Boston defeated the Yankees 3 games to 1. This marks the first time in franchise history that they would lose in the postseason as a Wild Card team in back-to-back seasons.
