There's got to be something they've done to the ball itself. The year-to-year comparison of batted balls shows that the likelihood of a ball hit 95+ mph off the bat is only slightly down this year, but then chances of such a ball leaving the yard are WAY down from last year. It should go up slightly as the weather warms up, but jeez, not that much.

Last year there were about 10.2 baseballs hit 95+ mph off the bat per game. Those events became hits 48.8% of the time (i.e. hitters have a .488 BA when they hit the ball 95+ mph), and were homers 11.96% of the time.

This year, so far, there are slightly fewer such events, only 9.93 per game, a decrease of about 2.6%. The batting average on those is only .451, a 7.6% decrease from last year. Maybe the humidors, maybe the increased shifting, etc. could account for that, but probably not.

But the real kicker is that the chances of those batted balls becoming a homer have dropped to just 8.91%, a decrease of 25.5% from 2021!

Given that hits are coming off the bat at high speeds at a rate almost the same as last year, this can clearly not be blamed on humidors. That would change the exit velocity, I would think.

Which means it has to be the drag coefficient on the ball. Maybe the leather is slightly rougher. Maybe the seams are slightly higher. I don't know. But I bet MLB knows EXACTLY what it did, and it just isn't telling. Joe made a comment once a couple of years ago about how the PGA knows exactly what the golf ball does in every way imaginable, and was incredulous that MLB said they really didn't know. I would posit that MLB does in fact know, but they pretend ignorance so they can screw around with things when they perceive a need to do so and then plead innocence when things backfire on them.

Something that is masking the decline of offense a bit this season. We have a universal DH.
