Major League Baseball has traditionally had the smallest postseason field of the four major North American sports leagues. However, in recent years MLB has started following in the footsteps of its competitors. 2022 marked the first season of a revised postseason format, in which six teams made the postseason for both the National and American Leagues - up from five in previous years and four from 1994-2011. These six teams are comprised of three division winners (receiving the top three seeds) and three wild card teams. The top two division winners receive a bye to the best-of-five League Division Series, while the the other four teams play in a best-of-three Wild Card Series.

I thought it would be an interesting exercise to explore what an expanded postseason format would have looked like historically in MLB. Specifically, I wanted to look at the era from 1969 to 1993, during which both the AL and NL had two divisions. In that period, the winners of the two divisions played in a League Championship Series, initially best-of-five, then best-of-seven from 1985 onward.
Under my hypothetical six-team format, the two division winners would have advanced automatically to a best-of-five League Division Series, while four wild card teams would have played each other in a best-of-three Wild Card Series. This marks a key departure from today's format in two respects: no division winner has to play a Wild Card Series, and it is guaranteed that the team with the second-best record in a league would not have to play the team with the best record prior to the LCS, regardless of if they are a wild card team or division winner.
Before I share what this would have looked like for each season, I want to make a few observations. First, one key advantage of this format would have been that it ensures that the team with the second-best record would have had an opportunity to reach the World Series via the postseason. In many seasons from 1969-1993, a team with the second-best record lost their own division race, while a team with an inferior record won the opposite division. Notably, twice a team won 100+ regular season games but failed to make the postseason - the Baltimore Orioles in 1980 and the San Francisco Giants in 1993.
Another observation is that while there may be concerns about the quality of teams reaching the postseason in an expanded format, the reality is that upwards of 97% of teams that hypothetically would have made the postseason would have had a .500 or better win percentage. Only 7 out of 300 teams would have made it in with a losing record. Considering that both leagues had at least 12 teams throughout it stands to reason that a format sending the top-half of the league to the postseason would generally result in teams with winning records making it in. Indeed the expansion of the American League to 14 teams in 1977 would have all but guaranteed this, with only one losing team potentially making the postseason in 17 seasons. Conversly, there still exists the possibility that teams with winning records would still miss the postseason, more so in the American League after the 1977 expansion. Those teams are also noted below.
Lastly, a note that this exercise cannot account for every change that this format would have potentially induced - particularly personnel decisions or managerial strategies for teams that would have now found themselves in playoff races they were not in otherwise. I do try to account for obvious changes that can be easily accounted for. Most notably, the absence of playoffs to decide division winners or wild cards in the new format is reflected through the use of tiebreaker criteria. This results, for instance, in the Los Angeles Dodgers winning the NL West over the Houston Astros in 1980 via a head-to-head record tiebreaker as opposed to a one-game playoff.
