What a little pitch-tracking app saw in the 2026 World Series.

October baseball is a different sport wearing the same uniforms.

In July, a starter gets six innings and a long leash. In October, he gets a hook the moment the third time through the order looks shaky. Aces pitch on short rest. Relievers who were anonymous in June become household names in a week. Managers who spent the summer saving arms spend the fall burning them, because there is no tomorrow to save them for.

Which makes October the most interesting month of the year to watch pitchers. So this year, I watched them twice: once on the couch, and once through a small app I built early this 2026 season to keep tabs on what starters were throwing.

The Brewers won it in five. What the app saw along the way was not quite the Series I thought I was watching.

The app, briefly

It's a modest thing.…
