As Dan points out, the Marlins haven't been a legit playoff team for 20 years. "The "last in the National League" Nationals, on the other hand, won four division titles between 2012 and 2018 and then won the World Series in 2019. That's as many World Series, by the way, as the Braves won despite winning 14 division titles from 1991 to 2005. Washington is in a rebuilt that its fans hope will mirror the Astros from 2012-14 before becoming dominant again.
