From SABR member Jay Jaffe at FanGraphs on March 18, 2020:
Poor Ernie Lombardi. The heavyset and heavy-hitting Hall of Fame catcher, who owns two of the position’s eight batting titles, was the player hardest-hit by Baseball-Reference’s latest update to their version of Wins Above Replacement. B-Ref rolled out a whole series of adjustments, both to current players and long-retired ones, into one big release earlier this week, which it explained via a Twitter thread on Tuesday morning and expounded upon at the site. Thanks to additional play-by-play baserunning and caught stealing data, Lombardi, whose career spanned from 1931-47, saw his career WAR total drop from 46.8 to 39.5. Well, he didn’t actually see it, as he’s been dead since 1977, but you know what I mean.
B-Ref’s version of WAR is different from that of FanGraphs, of course, though you may have noticed that our site also updated its Defensive Runs Saved totals after Sports Info Solutions made major changes to its flagship stat, in part to account for defensive shifting. I’ll get to that aspect in a separate follow-up post, but for the moment my concern is how the B-Ref changes affect my JAWS system for Hall of Fame evaluations. The overall answer is “not a whole lot,” though individual player WAR and JAWS, and thus the standards at each position, have shifted a bit, creating a ripple effect throughout my system. With no new baseball for the foreseeable future, it’s worth taking an inventory of these changes, in part because they give us a chance to dig into some baseball history and provide a bit of an escape from our current realities.
