As almost everyone is aware, the current MLB schedule is unbalanced. In 2015 every team played 19 games against each division opponent for a total of 76 games (except for one cancellation between Cleveland and Detroit), either 6 or 7 games against each team in the other two divisions of its league for a total of 66 games and either 3,4 or 6 games against teams from the other league for a total of 20 games. There has been some criticism of the unbalanced schedule. An unbalanced schedule means that teams competing for wild card berths in the postseason can have quite different strengths of schedule. Some feel that a lower number of intradivision games and the resulting increase in the number of games against opponents outside the division would increase fan interest. On the other hand, some feel that a higher number of intradivision games increases fan interest by promoting stronger rivalries. So how could MLB institute a completely balanced schedule? Involving all 30 teams would probably mean each team playing every other team six times for a total of 174 games, leaving time for only one postseason series. Either the top team in each league would advance to the World Series or the two teams with the best records would advance. (Instituting this schedule would probably force MLB either to adopt the DH for every game or to eliminate it.) Keeping the leagues separate would not be possible with two 15-team leagues. Barring expansion or contraction that means returning to one 14-team league and one 16-team league. In the 14-team league it would probably mean each team playing every other team 12 times for a total of 156 games, and in a 16-team league it would probably mean each team playing every other team 10 times for a total of 150 games. Taking this even further, keeping the current divisions separate would probably mean each team playing every other team 40 times for a total of 160 games. Nostalgia for the pre-1969 era notwithstanding, I think most people would agree that none of these options is satisfactory. So we’re left with the conclusion that an unbalanced schedule is inevitable. The issue, then, is how the games should be apportioned. There are many possible permutations. Working from the premise that there would be no realignment I played with the numbers a little bit to come up with one alternative to the current schedule that reduces the number of intradivision games. In this plan every team plays 14 games against each team in its division for a total of 56 games, 9 games against each team in the other two divisions of its league for a total of 90 games and 16 interleague games. For the interleague games each division would be matched against one division in the other league. There would be 3 games against each of four of the teams in that division and 4 games against one team in that division. For most teams, switching to this schedule means increasing the amount of travel across two or three time zones. (Texas and Houston are exceptions to this.) Not only is this more fatiguing for teams but TV and radio ratings drop for games aired earlier or later than during prime time. The fatigue issue is a bigger factor for teams located in the Eastern and Pacific time zones. Creative scheduling could make this more fair by requiring teams from the Central and Mountain time zones to have some road trips that incorporate traveling across three time zones. I wondered how a change in schedule would have affected the 2015 standings. To get an idea of that I took the percentage of games each team won against each other team this year and applied that to this alternative plan. 29 of the 30 teams would have finished with a different record but there would have been only two shifts in the standings. In one case Boston would have finished fourth in the AL East and Tampa Bay fifth instead of the other way around. In the other case, a more significant one, Pittsburgh would have finished first in the NL Central and St. Louis second instead of the other way around. (This is primarily because Pittsburgh was .447 vs the NL Central and .744 in the rest of its games.) The same 10 teams would have advanced to the postseason, but obviously Pittsburgh would have been the NL Central winner and St. Louis would have been the first-seeded wild card team. My interpretation of this analysis is that changing the current schedule would probably not be considered to be a significant enough improvement to warrant the making the change. The increase in cross-time-zone travel and the elimination of the so-called rivalry series in interleague play that MLB seems to love make it unlikely that MLB would consider such a change. It appears we will continue to see our current division rivals 19 times a year for the foreseeable future.
