In Billy Joel's song "We Didn't Start the Fire", what sport gets implied twice?

In Billy Joel's song "We Didn't Start the Fire" (1989), the sport that gets implied twice is baseball. Billy Joel told news media that his concept for “We Didn't Start the Fire” was to review major events that had happened during his own lifetime, from his birth in 1949 through the release of the song in 1989. This song is a dizzying kaleidoscope of many headlines over a span of 40 years, summing up some very key events of the late Twentieth Century.

First, in verse two, baseball is perceptively noted. The lyrics point out that Brooklyn's got a winning team (Brooklyn Dodgers, Major League Baseball team). Second, baseball is mentioned again in verse three; the words 'California baseball' are shrewdly used.

It is clear that with this song Joel placed the priorities and needs of his listening audience before his own. He has cleverly tried to point to items that have some social relevance and will highlight their societal effects on the world's existing adult and pop culture.
