The difference between the LaHair argument and this is that Lake's peripherals haven't changed all that much. He just had a crazy BABIP early, which we all knew wasn't sustainable. This is the fun of splitting player's data down arbitrarily. We can make it look like whatever we want. Lake's July - 310/333/466, 3.3% BB, 21.3% K Lake's August - 306/358/452, 6.0% BB, 25.0% K Both of those come with unsustainable BABIPs, but it's not as if he hasn't performed across his entire sample.
