Ian Anderson’s First-Inning Issues: Fact or Fiction?
Ian Anderson had a rough go of first innings this year. In 24 games, he compiled a 6.38 ERA, and this isn’t some case of a pile of seeing-eye singles doing him in. He allowed 2.3 home runs per nine innings, walked 14.2% of the batters he faced, and generally let the offense do what they wanted. His numbers worked out to a 5.29 FIP, which hardly seems like a fair representation of his skill. In every other inning he pitched this year, he was comparatively excellent: 0.9 home runs per nine, an 8.8% walk rate, and sterling run prevention numbers (2.93 ERA, 3.71 FIP).
I hate to use the word “narrative” because it’s mostly a lazy baseball writer crutch, but it’s unavoidable here: the narrative that Anderson is vulnerable in the first inning and bulletproof afterwards has been omnipresent in his playoff starts. When he gave up a first-inning home run to Corey Seager in Game 2 of the NLCS, it was something obvious to point to. First inning? Must just be Anderson’s unique flaw, a magic spell that makes him terrible until he gets a chance to grab some sweet dugout pine.
If you can’t tell from the way I’ve described it, I’m skeptical. Splits like that feel too hand-wavy, too post hoc ergo propter hoc, if you’re into being pretentious like I am. Every pitcher has to be worst in some inning, by sheer chance alone, even if their true talent never wavers. If I had my druthers, I’d just ignore the whole thing and go back to watching dugout celebrations. But because the first inning is the first, rather than the third or the sixth or any other random number, I thought I’d do an investigation into how much we should believe it.
