Hi there. I’m back from hibernation with my first interactive visual. Click on the image below and try it out! As always, comments / suggestions are appreciated. (For those of you who may not be familiar with Rankometer and how it works, I’ve added a brief description further down in this post).
Rankometer is a tool that helps you get a quick visual snapshot of a team (in this case the pitching staff) by ranking each of its 5 starting pitchers and 2 best relievers. Rankometer is based on the philosophy of comparing players relative to their peer group and ranking them accordingly. For the starting rotation, we look at each team’s best starting pitcher (described in the first column as #1 STARTER) and rank them based on a chosen stat (in this case we are using an advanced metric called xFIP which is an adjusted earned run average stat). We do the same for each team’s second best starter, third best starter, and so on. The same is done for the team’s best 2 relievers (using a stat called Win Probability Added). With this basic ranking structure in place, we can select any team and see a visualization of how that team’s pitching staff ranks relative to other staffs in the league. Rankometer does this by shading a column below each pitcher on the chosen team, creating a graphic equalizer effect that indicates how good a pitching staff is (tall bars indicate high rankings, low bars indicate low rankings). One additional note: I’ve been updating the stats manually (I haven’t figured out yet how to do that automatically) so the data is a few weeks old. In the future I’d like to have the data updated on a daily basis).
