The Nastiest Pitches of 2021: Filthy Four

Four pitches remain in the battle of the best

With the calendar officially flipped to 2022, it’s time to take one final look back at 2021 and relive some of the Nastiest Pitches of the year. We’ve hand-picked sixteen of the nastiest, filthiest, most disgusting acts committed by pitchers during the season, and it’s now up to you to vote and determine which pitch will be crowned Pitcher List’s Nastiest Pitch of 2021.

Voting has closed for the first two rounds, but click here if you’d like to look back and see all sixteen pitches in all their glory. For this round, voting will run throughout the day and every vote counts. Each round will run this week and the winner will be announced on Twitter on Saturday.

We’re down to four pitches for the Filthy Four, so let’s not waste any more time.


Shane McClanahan’s Sinker (1)





Kevin Gausman’s Splitter (1)



Kevin Gausman‘s splitter is the only non-sinker in this year’s Filthy Four, which shows that our voters might have a sinker bias. Duly noted. I’m also a sinker guy myself, but nobody can argue that Gausman’s splitter isn’t straight-up filthy. This is also a battle between the Nastiest Pitch of May (Gausman) and the Nastiest Pitch of April (McClanahan), so at this point, we’re also trying to decide which month of the Gregorian Calendar is the best. A tough task no doubt, but I believe in the readers to make the right choice.


Which Pitch Was Nastier?


Diego Castillo’s Sinker (2)





Blake Treinen’s Sinker (2)



In the last round, Diego Castillo took down Logan Webb in the battle of the sinkers. Does his pitch have what it takes to take down the nastiest pitcher in baseball in another battle between filthy sinkers, or will Treinen’s pitch ride and break its way into the championship?
