Best NRFI Bets Today: Winning Strategy for First Inning Betting
An NRFI bet wins if neither team scores in the first inning. It’s often listed as “Under 0.5 Runs – 1st Inning” at major sportsbooks. While it might seem like a coin flip, there are real edges to be found with the right data.
How to Identify the Best NRFI Today
The best NRFI bets today rely on four critical inputs:
Starting Pitcher First-Inning Performance
Before anything else, check how each starting pitcher performs in the first inning. A low 1st-inning ERA, WHIP, and strikeout rate are green flags for NRFI. Be wary of pitchers with high walk rates or trouble facing top-of-the-order bats early.
Pro Tip: Use FanGraphs and Baseball Savant to find 1st-inning splits for each starter.
Top-of-the-Order Matchups
Focus on the first 3–4 hitters from each lineup. Weak contact hitters, high strikeout rates, or missing stars boost NRFI value. Conversely, if a team’s leadoff trio includes elite bats (think Ohtani-Betts–Freeman), it’s probably a YRFI spot instead.
Pro Tip: Wait for confirmed lineups to make sure key bats aren’t unexpectedly rested.
Ballpark & Weather Factors
Wind blowing in? Cold night game? Pitcher’s park? These all favor NRFI. Ballparks like Miami and San Francisco consistently rank among the lowest for early scoring.
Team First-Inning Trends
Some teams just don’t start hot. Historical NRFI records, 1st-inning runs per game, and combined NRFI percentages all offer clues. Matchups featuring two low-scoring teams are goldmines for the best NRFI today.

Don’t Overpay: Line Shopping Matters
NRFI odds vary widely across sportsbooks. At -130, the implied win rate is 56.5%. If your data suggests the true probability is 60%, that’s value. But if the line moves to -160, the edge disappears.
