The Miami Marlins are a baseball team.
The Miami Marlins are an American professional baseball team based in Miami , Florida . The Marlins have the distinction of winning a World Series championship in both seasons they qualified for the postseason , doing so in 1997 and 2003 -- both times as the National League wild card team . They defeated the American League ( AL ) champion Cleveland Indians in the 1997 World Series , which was notable for shortstop Édgar Rentería driving in second baseman Craig Counsell for the series-clinching run in the 11th inning of the seventh and deciding game .
