The Best & Worst of Pitcher Strike Zones, With Dallas Keuchel
A couple weeks ago, I examined, on the team level, who has and hasn’t been drawing a benefit from the called strike zone. That post is here, and it talks about the zone while pitching, and about the zone while hitting. Earlier this very week, I looked at some individual hitter strike zones through the season’s first half, and that post is here. It makes sense to look at individual pitchers. If we have the team data, and if we have some individual hitter data, why not close the loop? I don’t want to leave you wanting more. I want to leave you never wanting to hear about this stuff again, or at least not for a while.
When a hitter’s had a particularly big or small strike zone, that seems to be luck, for the most part. Some of it’s the competition, but there doesn’t seem to be much of a signal. With pitchers, there’s more of a signal, because they’re the ones in control. And they’re also linked to their catchers, who might be good or bad pitch-framers. If a hitter’s been, say, lucky with strikes, that hardly means anything going forward. But if a pitcher’s racked up extra strikes, that bodes well for what’s to come. That’s something to keep in mind when you read all the rest.
We’ll be looking at pitchers with more or fewer strikes than expected. As you peruse the tables, you’ll be seeing evidence of skill, but skill that leaves many frustrated. Pitchers with good command tend to get more favorable zones than pitchers with bad command. And pitchers with good receivers will get more favorable zones than pitchers with bad receivers. Command is a developed skill, and receiving is a developed skill, but to a lot of people, the strike zone is the strike zone, and it shouldn’t shift around. To a lot of people, it should be called the same for everybody. It’s not! Maybe one day. For now, we’re still in our day.
