MLB NRFI picks, explained

No Run First Inning (NRFI) is a bet that neither team scores in the first inning of an MLB game. Historically, roughly 55–60% of games finish with a scoreless first inning, which makes NRFI a slight favorite on average based on first-inning scoring splits from the MLB Stats API.

This dashboard ranks every game on today's slate by each probable starter's first-inning ERA and WHIP, the opposing lineup's first-inning scoring rate, active NRFI and YRFI streaks, ballpark run factors, weather, and umpire tendencies. Probable starters and matchups refresh daily before first pitch.

What does NRFI mean in baseball betting?

NRFI stands for No Run First Inning. It is a popular baseball prop bet where you wager that neither team will score a run in the first inning of a game. The opposite bet, YRFI (Yes Run First Inning), means you predict at least one run will be scored in the first inning.

What makes a good NRFI bet?

A good NRFI bet typically involves starting pitchers with low first-inning ERAs, teams with low first-inning scoring rates, long active NRFI streaks, and pitcher-friendly ballparks. The best NRFI matchups feature two dominant starters facing lineups that struggle to score early.

How are NRFI probabilities calculated?

NRFI probabilities are calculated by combining multiple factors: each starting pitcher's first-inning ERA and WHIP, the opposing lineup's first-inning scoring rate, active NRFI/YRFI streaks for each team, and ballpark factors that affect run scoring.

How often do NRFI bets win?

Approximately 55-60% of MLB games result in no runs scored in the first inning, making NRFI a slightly favorable outcome on average. However, the actual win rate varies significantly based on the specific pitcher matchup, teams involved, and ballpark.
