There are problems with baseball, including performance-enhancing drugs and exorbitant salaries, and it is unlikely baseball will surpass football in popularity in the near future. But it is still America’s second-favorite sport, with 14 percent of respondents to a January Harris poll calling baseball their favorite. More importantly, though, it is America’s pastime. It needs to be cleaned up and sped up, but it should not be redesigned to attract a wider fanbase at the expense of those who like it the way it is. Baseball can be improved, but it does not need drastic reforms that would dilute its traditional undergirding.
