This Day in New York Yankees History 11/20: Mussina Retires

On this day in 2008  Mike Mussina officially announced his retirement following his first 20 game winning season. Moose spent 10 years with the Baltimore Orioles before spending his last eight seasons with New York. Moose finished with a 270-153 record with a 3.68 ERA combined in his soon to be Hall of Fame career.

Also on this day in 2008 the 35 year run of George Steinbrenner being the owner of the New York Yankees officially ended as the MLB owners unanimously approved of his sons, Hank and Hal Steinbrenner, taking over the Yankees. George, with his failing health, appointed his sons as the chairmen of the team in 2007 before this was made official.
