About NRFI Stats
NRFI (No Runs First Inning) tracks whether a starting pitcher holds the opposing lineup scoreless in the first inning. A high NRFI rate indicates a pitcher who consistently gets through the first without giving up runs — a key signal for first-inning prop bets.
Through 31 starts this season, Imanaga has held the first inning scoreless 22 times (71.0% NRFI rate). He's averaging 0.52 runs, 0.87 hits, 1.29 Ks, and 0.26 walks per first inning this season.
Opening Line Analytics combines Imanaga's historical stats with real-time lineup data and 10,000-iteration Monte Carlo simulation to generate a combined NRFI probability before every start.
