The Astros are the only franchise without a playoff appearance to this point.
The Mariners, Rockies and Angels lead with 15 and, while the M's have converted three of those appearances into OFA Championships, neither of the other two have won it all. The Halos' 1836-1404 (.567) record is the best; the Rays 1481-1760 (.457) the worst.
Some of those annoying "ghost stats" have polluted the leaderboards. So ignore anything you see before 1901.
