Yankees manager Aaron Boone watched the hits begin to pile up on the massive, crown-shaped scoreboard beyond the centerfield wall at Kauffman Stadium, and he knew that his team was doing something impressive against the Kansas City Royals.

He didn't know until afterward that it was something historic.

Yes, there were six home runs, including two from Amed Rosario. And the Yankees put up 24 hits in the 15-1 romp, their most since a game against Baltimore in July 2011. But what set the performance apart from all others Tuesday night -- including all those games played by Lou Gehrig and Babe Ruth, Joe DiMaggio and Mickey Mantle -- was this simple fact: For the first time in their storied history, the Yankees got at least two hits from every single player in their starting lineup.
