One of my last comments before we turned the page...

Whichever league he pitched in, whichever ballpark he called home, perhaps Mike Leake just had a lot of very unfortunate baseballs tossed to him by the home plate ump?

Robert Arthur writing in BP about findings of the panel of scientists trying to figure out if the baseball was different this year:

Year To Year Variation Has Been Large, But Ball To Ball Variation Is Massive

In explaining the results of the study, MLB took a tack of noting that changes in drag from one year to the next are small compared to the difference between any pair of baseballs. That’s true, but it’s nothing we didn’t know before, and it makes the findings the committee observed sound minor when they aren’t. After all, if year to year variation is smaller than something else, maybe it isn’t such a big deal after all?

This defense is empty because it’s usually the case that when you compare a pair of samples of multiple measurements, variation is smaller than for any individual data point in the sample. In this case, individual balls vary in their flight by up to 30 feet, whereas annual averages differ by a mere 5-10 feet.

But both represent major issues for MLB. The former, ball to ball variation means that a pitcher could grab one baseball that would become a certain home run, while the ball next to it would be an easy flyout. Any given postseason game or pitcher start could be made or broken by the particular baseball they happen to get in that moment.
