I've heard some all-time franchise stats before, scattered here and there from announcers or talk show hosts. I've wanted to collect or calculate some franchise stats for a long time now. Fortunately the Baseball Reference [dot] com website has some sortable data that is easily accessible.
So, in case you've wondered about all-time rankings for franchises, I can tell you about a great franchise: the Giants. The Giants are the winningest franchise in baseball history, winning more games than any other franchise, ahead by several hundred wins. Of course, the NL is older than the AL, so it stands to reason that the Giants would have more wins than the Yankees. The Giants are surpassed in winning percentage by only the Yankees. The Giants have more hall-of-fame players than any other franchise, by far. Only the Cubs have scored more runs; only the Yankees have hit more home runs; only the Yankees have won more pennants; and by the slimmest of margins, only the Dodgers have a better all-time ERA.
The Yankees, Cardinals and A's are the only teams with more World Series championships, but looking at the Giants history, they should have won more than the A's and Cards. But they didn't. Maybe they will pass these teams in the next decade or so (as they owe it to their starved fans). Go Giants!
