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 28 starts this season, Yamamoto has held the first inning scoreless 20 times (71.4% NRFI rate). He's averaging 0.39 runs, 0.82 hits, 0.82 Ks, and 0.36 walks per first inning this season.

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