I should start with the usual caveats and disclaimers. I use the word aggregate because it is the numerical average of all of the numbers. It doesn’t represent differences in who actually gets the plate appearances. It also doesn’t represent the actual roster employed last season. In particular, Nick Allen is much more patient than Mauricio Dubon, so we included Allen because coaches have to be graded based on what they do with what they have and not based on what they have.

Dans Brown’s job is to give Joe Espada the very best roster he can. Espada’s job is to employ that roster to maximum effect. From there, the hitting and pitching coaches are charged with getting as many of their charges to hit or pitch their very best. Given all of those caveats we can begin to digest these numbers to figure out what they might mean long-term.

We will start on the right hand side of the ledger. The zone percentage represents the percentage of pitches that hitters see in the zone. Clearly, teams are not challenging Astros hitters very much. Of course, there are multiple reasons for that. On the one hand, it could be a bigger trend based on past performance. If I were coaching against the Astros, I would probably tell me pitchers to test the Astros hitters and their strike zone judgment. In particular, Diaz, Altuve, and Pena have been free swingers. Why give them a lot to hit?

On the other hand, they have gone up against three teams so far. Even if we include the Rockies, we would see four teams expected to be near the bottom of the standings. The Red Sox might be the notable exception to that rule, but no one has high hopes for the Athletics, Angels, or Rockies pitchers. So, maybe they are just incapable of getting it in the zone consistently.

Either way, the Astros have responded by swinging less often and chasing less often. I’m certain that the actual 2025 numbers would be worse than what we see above. So, the difference is that much more stark. It clearly reflects the messaging going to hitters. Of course, only those inside the clubhouse would know whether the message has changed considerably. Often the key to good coaching is not the message itself, but in how it is communicated. Clearly, the message is the right one and so far it is being communicated in a way most of the hitters can digest. From here, Joe Espada will need to manipulate the lineups to take fuller advantage of those performing and Brown will need to shape the roster by possibly moving some of these guys not performing. That is the way this whole thing works. Of course, the rubber will meet the road when the Astros finally see a good pitching staff in Seattle.
