Dudley was the Indians' lead announcer from 1948 until his firing by the club in January 1968. In 1969, Dudley broadcast for the expansion Seattle Pilots; when the club moved to Milwaukee and became the Brewers the following year, he did not join them. Dudley broadcast for a number of minor league teams in the 1970s before retiring. As an announcer, Dudley was known for his friendly, homespun style and his signature catchphrases: "Hello, baseball fans everywhere" (to start a broadcast), "The string is out" (describing a full count on a hitter), "A swing and a miss!-he struck him out", "That ball is going...going...gone!" (to describe a home run) and "So long and lots of good luck, you hear?" (signing off at the game's end). Dudley called the 1954 World Series and All-Star Game for the Mutual network, and 1961's first All-Star Game for NBC Radio.
