NEW YORK — Aaron Boone’s hiring was finalized Monday by the New York Yankees, who gave the ESPN broadcaster a three-year contract to succeed Joe Girardi as manager.

New York, which picked Boone over five other candidates last week, scheduled a news conference for Wednesday at Yankee Stadium. His deal contains a team option for 2021.

“I firmly believe that Aaron possesses the attributes needed to follow in the tradition of great Yankees managers,” owner Hal Steinbrenner said in a statement. “From all accounts, he is a polished communicator who possesses the ability to cultivate and grow relationships. Aaron has also spent a lifetime immersed in baseball, affording him a unique and intimate understanding of what fosters team success.”

Now 44, Boone has never been a manager or even a coach at any level since retiring as a player after the 2009 season. His 11th-inning home run off Boston’s Tim Wakefield won Game 7 of the 2003 ALCS for the Yankees.
