Aaron Boone is officially the Yankees manager.

The team made the announcement on Monday, with Boone signing a three-year deal that includes a team option for 2021. He will be introduced at a press conference at Yankee Stadium on Wednesday.

Boone replaces Joe Girardi, whose contract was not renewed following last season, despite the Yankees having exceeded expectations by reaching the ALCS and falling one win short of the World Series.

General manager Brian Cashman praised Boone’s open-mindedness in a statement.

“When we had the opportunity to speak with Aaron and share concepts and ideas, he was able to showcase a variety of traits that we believe will strongly benefit this franchise as we move forward, including an astute mind for the game and a progressive approach to evolving strategies,” Cashman said of Boone, who has never coached or managed at any level.

Despite Boone’s lack of experience, Cashman also pointed to Boone’s ability to connect with players, as well as an ability to “collaborate” with the front office, both of which were issues that helped lead to Girardi not being retained.
