How We / Pick

No touts · No tails · Just the model

— 01

Pitching & Matchups

MLB: SP xFIP, SIERA, velocity trends weighted by park & lineup wOBA vs. handedness. NBA: player usage, rest advantage, back-to-back penalties.

— 02

Market Read

We track line movement across 8 books. Reverse line moves and steam trigger alerts that factor into our final confidence score — same for MLB runlines and NBA spreads.

— 03

Pace & Environment

MLB: wind, humidity, park HR/9 baseline for O/U. NBA: pace differential, altitude, and officiating crew pace (top-vs-bottom refs swing totals 4+ pts).

— 04

Fatigue & Availability

MLB: bullpen pitch counts over 3 days, leverage spots. NBA: injury reports scraped 30 min before tip, B2B net rating, minutes load on stars.
