The Almanac
Baseball intelligence, from the deadball era to today's Statcast age.
What it is
The Almanac is an AI-powered baseball analytics assistant. Ask it anything about players, seasons, matchups, or historical moments and it will query across three major datasets to give you an answer grounded in real data — not hallucinated stats.
Data Sources
Lahman Database
Comprehensive baseball statistics from 1871 to 2025. Batting, pitching, fielding, and franchise records spanning 150+ years.
Retrosheet
Play-by-play game logs from 1910 to 2025. Every at-bat, pitch sequence, and in-game event for over a century of baseball.
Statcast
Pitch-level tracking data from 2015 to 2025. Exit velocity, launch angle, spin rate, sprint speed, and expected metrics.
Powered by Claude
The Almanac uses Anthropic's Claude to interpret your questions, write SQL queries against the underlying databases, and synthesize results into clear, conversational answers. Claude brings contextual understanding of baseball — eras, rule changes, park factors — so the analysis goes beyond raw numbers.
