JD was a moment in time that might not be replicated. He was one of the first, almost ten years ago now, to seek out a data-driven personal hitting coach during the offseason to help him either augment or overcome what the Astros were teaching him. In the parlance of sabermetrics, JD exploited a market inefficiency before his opponents, i.e. other hitters, caught on. And we were the lucky beneficiaries of that, although too late to help us during our division-winning run. He was easing into his best stretch run of his career, and fucking Al Avila couldn’t get rid of him for a bag of used batting practice baseballs fast enough.
