In the National League, the Atlanta Braves made their eighth straight postseason appearance, the Houston Astros made their third straight appearance, the New York Mets made their first appearance since 1988, and the Arizona Diamondbacks made their postseason debut two years into their existence.
The postseason began on October 5, 1999, and ended on October 27, 1999, with the Yankees sweeping the Braves in the 1999 World Series. It was the Yankees' 25th title, which made the Yankees the team with the most championship wins in North American sports, surpassing the Montreal Canadiens who won 24.[2]
