Public address announcer Bob Sheppard, known as the “Voice of Yankee Stadium,” died Sunday at his home in Baldwin, New York at age 99. Sheppard announced his first game at the Yankee’s home opened on April 17, 1951, and worked until his retirement in 2007, according to a statement released by the Yankees. His career spanned 4,500 baseball games, including 121 playoff contests and 52 World Series games. During his 56 years at the microphone, Sheppard witnessed a number of career highlights, like Roger Maris’ 61st home run in 1961 and Reggie Jackson’s three-homer game at the World Series in 1977. In addition to the Yankees, Sheppard was the announcer for the NFL’s Giants for 50 seasons, as well as for other sports teams in New York at all levels.
