The New York Yankees on Wednesday officially announced their new manager.

Former infielder Aaron Boone was named the 33rd manager in franchise history, signing a three-year contract with a club option for 2021.

"Obviously the expectations here with the New York Yankees is to win championships and certainly that's always the goal when we set out each and every year, but what I'm most looking forward to is the chance to have an impact on young men, on young ball players, and be a part of them taking the next step to become championship-level players," Boone said at his introductory news conference.

The ex-Yankee and ESPN commentator has never managed or coached a major league or minor league team before.

But he did help the Bronx Bombers clinch the American League pennant with his walk-off home run in the bottom of the 11th inning in Game 7 of the 2003 World Series.

He replaces Joe Girardi, who had been the team's manager since 2008, but was not offered a new contract after the season ended.

Boone is the 18th Yankee manager to have also played for the team.
