Ballpark Figures is a passion project that attempts to make baseball statistics and sabermetrics more accessible to fans through thoughtful and interactive data visualization and instruction.

As a lifelong New York Mets fan, I have been indebted to fangraphs.com for helping me understand the construction of teams, player performance, and the day's games. My goal here is to extend the functionality of their immense work, and not to compete with them (love you guys), to make complex statistics a more visually interpretable and intuitive experience.

This project started from a Mets-specific place: attempting to quantify how frustrating the 2026 Mets have been and what our general manager David Stearns should be seeing in his decision-making, but very quickly, I realized this work brings together my favorite things: baseball, neat plots, data science, and interactive journalism.

I also would like to shout out to the developers and analysts at Baseball Savant, Statcast, PitchFX, Baseball Reference, Fangraphs, and the publicly available baseball data tools that have made this effort possible.

I hope you enjoy the work and website.
