He was widely seen as a potential successor to then-manager Joe Torre, but when Torre stepped down in 2007, Mattingly was passed over for the job in favor of Joe Girardi.Mattingly left the Yankees to become the hitting coach for the Los Angeles Dodgers before being promoted to manager in 2011.Don Mattingly already having an influence on the Blue Jays benchThe Toronto Blue Jays have had a decent start to their 2023 MLB campaign and currently sit in second place in the American League East table. New bench coach Don Mattingly has no doubt had a huge impact on the team and is one of the reasons for their consistent performances.In the end, Mattingly will always be a beloved figure in the Yankees community, regardless of where his coaching career takes him. While his absence may be felt by many, it's important for fans to continue to support the team and have faith in the coaching staff currently in place.
