Ever since Major League Baseball was founded in 1869, franchises have been relocated, renamed, players have come and gone and legends have been born and enshrined in history.
In the 143 years since baseball has been deemed a profession in America, 30 franchises have stood the test of time, each of them with their own incredible histories and traditions.
As a personal vice and out of curiosity, I compiled a spreadsheet calculating the all-time winning percentage of every franchise, including how often they appear in the postseason, win pennants and world championships, as well as how many of their playoff trips result in World Series berths and titles, relative to how long each team has been in existence.
The placement of some teams will be obvious, but others were a shock to me and may be to you as well.
Here are my rankings of the 30 current MLB franchises based on all-time records.
