One of the tricky things about having so many stats on the site is that it can sometimes make it difficult to figure out whether a particular player is “good” or “bad” in a given statistical category. The other thing that can further complicate matters is the ever changing league rates. Given that the league strikeout percentage has increased over 8% in the past 30 years, what was once considered a well above average strikeout rate might today be merely average.
That’s why we’re introducing the “+ Stats” section to our leaderboards, where we have season and league adjusted a number of stats for your perusal.
Just like wRC+ and ERA-, all of these stats have a baseline of 100, where the number above or below 100 is the percentage above or below average a player is. For instance, Pedro Martinez’s 1999 K%+ is 239, that means he was 139% above the league average.
We’ll periodically add other stats to this section, so if you have additional “+ Stats” you’d like to see, please let us know in the comments!
