The 1969 Cubs: a team that will forever be mentioned among pro sports' most epic collapses. The team spent a grand total of 155 days in first place and seemed destined to make a playoff run.
After Ken Holtzman threw a no-hitter on Aug. 19, the Cubs took their biggest division lead of the season, up 8.5 games on the Cardinals and 9.5 on the Mets. With all the momentum in the world on their side, they seemed well on their way to October.
However, they went on to lose 17 of their last 25 games in what was one of the largest collapses in sports history, as they finished a full eight games behind the "Miracle Mets," who won 38 of their last 49 games.
Many things have been blamed for the plunge: the fact that manager Leo Durocher ran the same lineup out day in and day out during the slide, the gaping hole in center field, the incredible lack of depth.
In the end, it was a combination of those things—and some bad luck—that made this team arguably the most talked about second-place team in baseball history.
