Dr. Anthony Fauci is warning of the potential dangers of letting the Major League Baseball season go too far into the fall.

The director of the National Institute of Allergy and Infectious Diseases was interviewed by the Los Angeles Times.

"If the question is time, I would try to keep it in the core summer months and end it not with the way we play the World Series, until the end of October when it's cold," Fauci said. "I would avoid that."

The end of the season has been a significant point of contention between MLB and the players' union.

The league has been consistent in its insistence that the regular season end Sept. 27. The union's most recent proposal of 89 games would have had the regular season end in mid-October.
