The Top 100 Pitchers of 2021

The day in between games 162 and the first Wild Card Game is one of my favorites of the year. It’s on that day that season stats are finalized, and I can really start measuring everything. To that end, welcome to my official 2021 pitcher power rankings.

Before diving into the list, I’ll clarify a few things. Pitchers are ranked by Score, which has a maximum value of 100. Score is the result of a formula that centers on Innings Pitched and Runs Allowed, both actual and estimates, but does have some more under-the-hood components. I report Score to one decimal place, but all ties on the list are ranked correctly by going out to more decimals. Starters and relievers are ranked alongside each other on this list, and the positions are considered one in the same. Every pitcher to take the mound in 2021 has been ranked.

Please keep in mind, these rankings are not predictive; they are simply a measurement of who was the best in 2021, not who will be the best in 2022. They also differ from the formula I use to guide my Cy Young rankings, as that one is more focused on results than process. Power rankings use both in tandem.

Below, as the title states, I will rank the top 100 pitchers by Score for 2021, including their name, 2021 team, Score, and power rank from the 2020 season. This is going to be a huge table. Get comfortable.
