On this day in 2008, Yankees starting pitcher Mike Mussina, a 20-game winner the previous season, announces his retirement, ending an 18-year career with the Orioles and the Yankees. 'Moose', who compiled a 270-153 record with a 3.68 ERA, left Baltimore after the 2000 season, signing an $88.5 million, six-year free-agent deal to play in the Bronx. #BronxFaithful #ThisDayInYankeesHistory
