How long has aaron boone been the manager of the yankees

As of October 8, 2026, Aaron Boone has served as the manager of the New York Yankees for nearly nine full seasons. Boone was officially hired for the position on December 4, 2017, succeeding long-time manager Joe Girardi. Throughout his tenure, which began with the 2018 MLB season, Boone has navigated the complexities of leading one of the most high-profile franchises in professional sports. His leadership has been characterized by consistent regular-season success and multiple postseason appearances, though the team has faced significant scrutiny regarding its inability to secure a World Series title during his time at the helm. Despite periodic speculation regarding his job security due to the intense pressure of the New York market, the organization has maintained its commitment to his leadership style and analytical approach. As the 2026 season concludes, Boone remains the primary figure in the Yankees' dugout, having overseen hundreds of games and managed a roster that has undergone significant transitions over the past nine years. His current standing reflects a long-term, albeit challenging, tenure in Major League Baseball.
