What matters for NRFI
- Starting pitchers’ first innings
- A pitcher’s full-game ERA hides how he starts. Look at his first-inning ERA and how often he keeps the first scoreless.
- The top of each lineup
- The first inning is the only one where you know who bats: the top three or four. Batter-vs-pitcher history helps a little; confirmed lineups help more.
- Umpire, park and weather
- A tight strike zone, a hitter’s park or wind blowing out all push toward a run.
- Price
- NRFI is often priced near -120 or worse. A 55% NRFI rate is not enough at that price.

It is the MLB off-season, so most NRFI boards are empty until Opening Day 2027.
We make The Betting Insider, so we are not neutral. We included it where it fits and said plainly where another tool does a job better.
