Here's empirical proof that “Fastball Freddy” may be a thing of the past, but “Frequent Freddy Four-Seamer” is still plenty alive.

Here’s a thread.

it’s time  

I love this idea and can’t wait to poke around. Is an open source repo (kinda like pybaseball) where people can vote on requested features and/or make PRs to add these features?

Whispers it honestly

Good start to the Mets season

I’m taking a stand with Stearns and his decision to not resign Pete the Polar Bear by only using Polars in my code going forward

What a show

Great article. It’s very intuitive. For the last two charts, does a similar correlation exist between Run Value & Stuff+?

Statcast Breakdown: Why Pitch Sequencing Matters - Metsmerized Online After 150 years of baseball, a simple question still remains: what pitch should come next? It’s a really difficult question to answer. Simply put, a pitch is not defined by a singular characteristic. ...

This is just the tip of the iceberg. There’s loads more just to be found - player, team, and platoon analysis are all available.

I’m excited to see what additional analysis materializes.

A recent article on MMO about this was recently published.

Surprisingly, the same pitch followed each other to identical spots pretty often.

My theories:

- When Diaz was ahead in the count, he threw the pitch in tandem to induce a swing-and-miss
- Regardless of count, his slider performed best low and away
- It generally follows Diaz’s usage patterns

The same sequential pitch so often seems strange but it’s actually very prevalent.

Take Edwin Diaz for example.

Diaz’s profile is interesting. From watching games, I assumed his fastball followed his slider often, but no.

In 2025, the Mets’s most frequent sequences: 

- Holmes: Sinker/ Sinker 365 times
- Manaea: Four-Seam Fastball/Four-Seam Fastball 306 times
- Diaz: Four-Seam Fastball/Four-Seam Fastball 282 times
- Stanek: Four-Seam Fastball/Four-Seam Fastball 281 times
- Diaz: Slider/Slider 241 times

I’ve spent the last few months thinking about Pitch Sequencing.

To look further into it, I made a living, breathing website to track the most frequent sequences from the 2025 MLB season.

Hell yeah

I’ve been writing about baseball for almost a decade now. Writing (and in general baseball analysis( has granted me so many opportunities. Somehow, I’ve even parlayed it to full-time employment.

There’s absolutely more still in the works and something (very cool imo) right on the horizon
