Welcome Back, Offense
Do you remember last offseason? Last offseason, it seemed like Major League Baseball had two primary goals. One, it wanted to make the game move faster. And two, it wanted to do something about the ongoing drop in run-scoring. They didn’t really have a plan in mind, but they said it was a thing they were going to monitor. Last September, runs scored per nine innings dropped below 4 for the first time this millennium. And last year, also for the first time this millennium, there was a month with a league-wide OPS below .700. Actually, there were three of those months, in just a four-month span. Offense was going down; everyone was aware. Baseball needs a certain minimum level of offense to survive.
There’s your setup. This year, to some extent, baseball has succeeded in trimming unnecessary delays. The game does go faster, even if it’ll never go fast. And then there’s the matter of run-scoring. Here’s one plot, of year-to-year R/9 averages:
Hey, look, a little rebound. Relative to last year, this year is up 0.21 runs per nine, getting back closer to 2012 levels. That’s interesting on its own. But this gets more interesting the closer you look.
