2016 – Rookies Tyler Austin and Aaron Judge hit back-to-back homers in their respective first major league at-bats in the 2nd inning to lead the Yankees to an 8 – 4 win over the Rays. No teammates had ever homered in their first at-bat in the same game, let alone back-to-back. The Yankees hit three more homers later in the day, by Starlin Castro, Aaron Hicks and Didi Gregorius, to put the game away; in a sign that the team’s youth movement is going well, not one of these players is over 25.
