From the Pittsburgh Pirates and Oakland Athletics of the early 1970s to the Houston Astros and Los Angeles Dodgers of today, we've pinpointed the best five-year stretch of every Major League Baseball team in modern history.
We're defining "modern history" as everything that has happened since the pitching mound was lowered after the 1968 season. (In one case, we overlap with pre-1968 seasons, but we'll get there shortly.) That's far enough back to cover a whole bunch of seasons but also recent enough that some fans of every franchise will vividly remember the peak.
Regular-season success is our primary focus.
