Zack Greinke Isn’t Out of the Woods
Since people take us for experts for some reason, we’re commonly asked what we consider important in the season’s very early going. What’s most important — and this should be abundantly clear — is that there’s active baseball in the first place. At the very least, there’s spring-training baseball, and as of just yesterday, there’s meaningful baseball. That’s it! That’s the whole point. Everything else is a detail.
But since we all get worked up over the details, we’re asked which details are most important early on. Statistically, the answer is, not much. A high or low batting average isn’t too suggestive. A high or low ERA isn’t too suggestive. A win or loss here or there are but ones of dozens. The more important things are the measurements that take less time than others to stabilize. Changes in, say, power. Changes in contact. Or changes in velocity. There are few things that stabilize in less time than how fast a pitcher throws. This is why so many of our March and April stories and tweets are about unusually fast or slow fastballs. This all brings us to Zack Greinke, the Diamondbacks’ opening-day starter.
