Some visualization scripts and baseball-related writing.
Diamond Notes. A very sporadically-updated blog. For a few years I wrote articles at sonsofsamhorn.com, which is now defunct; I'm very gradually moving some of my old columns from there to here.
Pitcher by season. A pitcher's pitch mix, velocity, and movement over a season (just 2018 so far)
Pitcher by game. A pitcher's velocity, pitch usages, and outcomes for a particular game
At-bat viewer. Show location and kind of pitches for pitcher/batter matchup
Pitch comparison animator. Compare two pitches by animating their paths in side and top view. I kind of got bored with this one so you can pick the pitcher and pitch type, and then it chooses a random pitch from that set.
