Jonathan Lucroy and the New Decline
Here’s a graph posted at Baseball Prospectus a week ago:
You see, for each of the last six years, an estimate of Jonathan Lucroy’s pitch-framing value. Now, there are freely available pitch-framing numbers you can browse through at StatCorner. Those will give you a good sense, but the numbers at Baseball Prospectus are the gold standard, with countless variables and adjustments, and what we observe when we look at Lucroy on Baseball Prospectus is that, statistically, it seems like his pitch-receiving has dropped almost all the way to league average. It was only a few years ago he ranked as one of the best, if not the best, so this is fairly astonishing. And Lucroy is said to be on the market, so this is also relevant. What are we supposed to believe as far as Lucroy and pitch-receiving go?
