FG on Fox: MLB’s Runs Per Hour Problem

New commissioner Rob Manfred is clearly not afraid of change. In his first 24 hours on the job, he postulated about a future of the sport that included pitch clocks but excluded defensive shifts, among other tweaks. Unlike the former commissioner — who famously hated computers — Manfred is a proponent of technology and wants to make sure baseball keeps itself relevant in a changing landscape of how fans consume sports and entertainment. In this day and age of screens everywhere, shorter is often better, and the commissioner seems serious about addressing the pace of play issue in Major League Baseball.

However, his comments about the shift came in the context of a stated desire to breathe some offense back into a sport that has shifted heavily towards the pitching side of the equation in recent years. With offense trending downwards, the league clearly feels there is a point at which rules may have to be adjusted to restore the balance between offense and defense, just as the league took action in 1969 (by lowering the mound) and again in 1973 (by introducing the Designated Hitter). While I’m among those who do not believe that restricting the shift would have much of an effect on increasing offense, the willingness to consider it as a remedy suggests that Manfred believes that current offensive levels are a potential problem for the sport.

So on the one hand, the league would like to speed up the games; on the other hand, the league would like the games to include more run scoring. This seems to be a bit of a paradox, given that the act of scoring runs inherently means that more time is spent doing things besides ticking off some of the 54 outs — or 51 outs, if the home team protects a ninth inning lead — allotted for each contest. More offense means more at-bats and often can mean more pitching changes, and those two things generally mean longer games.

But how closely does run scoring track with length of game? Is it such a clear relationship that any increase in offense would be immediately met with a corresponding uptick in the number of minutes in a contest? I wasn’t actually sure, so with the help of some data from our friends at Baseball Prospectus and Baseball-Reference, I lined up the average length of game with average team runs per game for each season since 1950. The results are displayed in the chart below.
