I’ve been excitedly waiting to share these charts. They're the culmination of a season’s worth of work on understanding pitcher arsenals, how they fit together, and how they impact batters’ pitch recognition. Allow me to introduce you to Baseball Prospectus’s new Arsenal Metrics.

if there’s a specific topic you’d like for me or @lambo.drivelinebaseball.com to explain more effectively, happy to do so here.

good a reason as any for me to jump in on bluesky.
