Mind the WAR Gap

Aaron Judge stands alone. Well, Aaron Judge usually stands alone. This year, he’s got company. Judge leads all players with 8.3 WAR. Shohei Ohtani is right behind him with 7.8 total WAR (6.5 as a hitter and 1.4 as a pitcher), and Cal Raleigh is right behind him with 7.6. With a difference of less than three-quarters of a win, that’s an extremely tight race to be baseball’s WAR leader. It got me wondering how often these races are that tight, so I hit the spreadsheets. I pulled the top three WAR-getters in each season since 1901 and checked to see whether this year’s race is an outlier, and if so, just how out there it is compared to seasons past. The short answer is yes, this race is really tight by pretty much any historical standard.
Before we get into it, I’ve got to make a couple notes on the data and methodology here. First, I used FanGraphs WAR, both because I work here and because I’m a FanGraphs fan. (I’m also a fan of FanGraphs’ graphs, which makes me FanGraphs graphs fan. I could keep going.) Ohtani leads baseball in WARP, Baseball Prospectus’ version of WAR. As Ginny Searle wrote on Wednesday over at BP, Judge leads Raleigh by much more in both Baseball Reference WAR (which doesn’t incorporate pitch framing) and WARP (because DRC+ thinks Raleigh’s deserved offensive performance is slightly below his actual performance). Still, we’re going with fWAR, or as we refer to it here at FanGraphs, WAR.
Second, no matter which version you use, you’re really not supposed to dice WAR up like this. It’s a great stat that captures a lot, but it has error bars like any stat, and there are probably bits of value players produce that we can’t measure. If you’re selecting an MVP or comparing any two players based on fractions of a win, you’re probably doing it wrong. But I double-checked, and it turns out that nobody’s going to fire me for handling WAR slightly irresponsibly. Today, we’ll have some fun doing it wrong. Read the rest of this entry »
