The worst MLB teams of the modern era

The modern era of Major League Baseball began in 1900, and while we've seen a slew of great teams in the century-plus since, we've also witnessed some historically dreadful campaigns.

Here we chronicle the 24 worst teams in MLB in the modern era based on the lowest winning percentage. Perhaps we should call it losing percentage?
