Bullpen Briefing
A live MLB companion that explains in plain English what each starting pitcher is doing tonight — arsenal shape, velocity bands, recent swing-and-miss patterns — and what to watch for in big at-bats.
Casual MLB fans who watch the game but don't read Pitching Ninja threads
- Pre-game pitcher card with a one-paragraph 'what makes him scary' summary
- Live arsenal dashboard tracking velocity, whiff rate, and pitch-mix shifts as the game unfolds
- Push notification when your favorite team's ace is on the mound with their recent form
- Post-game 'why he won/lost' recap citing the underlying pitch data
A 99 mph rookie ace dominating for a sub-.500 team is exactly the kind of story casual fans want to follow — but most broadcasts reduce it to 'he's got good stuff' instead of unpacking the slider.
MLB Statcast/tools pull meaningful traffic (Baseball Savant, FanGraphs, SoxSavant all major destinations), but attempts to verify 'Chase Burns' trend returned empty; casual-fan demand for plain-English pitching mechanics is plausible but unconfirmed by searches.Baseball Savant: Statcast, Trending MLB Players and Visualizations ↗FanGraphs Baseball | Baseball Statistics and Analysis ↗
Live in-game pitching narrative companion is genuinely underserved — Baseball Savant/FanGraphs/PitchQuery are post-game or look-up tools aimed at statheads, and Stockyard/SoxSavant emphasize leaderboards rather than narrative at-bat storytelling.Home | Stockyard Baseball ↗SoxSavant - Pitching Apps ↗
Direct competitors on Statcast pitching analytics (Baseball Savant, FanGraphs, PitchQuery) are all free, and sports-app subscription fatigue is real; ARPU likely low unless paired with ads, premium tiers, or team partnerships — none are obvious here.MLB Pitch Data & Statcast Analytics ↗Baseball Savant - Statcast Game Feed & Advanced Metrics ↗
MLB runs 162-game seasons with stable, durable interest; Statcast is now a decade-old data layer backed by MLB/Google Cloud and is unlikely to disappear, giving a multi-season runway.MLB case study | Google Cloud ↗
Public Statcast feeds plus an LLM can trivially translate Stuff+/whiff%/arsenal into plain English; main build cost is real-time pipeline + distribution to casual fans, not the model layer itself.Baseball Savant: Statcast, Trending MLB Players and Visualizations ↗
