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 15 starts this season, Imai has held the first inning scoreless 10 times (66.7% NRFI rate). He's averaging 0.87 runs, 1.20 hits, 1.27 Ks, and 1.27 walks per first inning this season.

Opening Line Analytics combines Imai's historical stats with real-time lineup data and 10,000-iteration Monte Carlo simulation to generate a combined NRFI probability before every start.
