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 6 starts this season, Mayza has held the first inning scoreless 4 times (66.7% NRFI rate). He's averaging 0.67 runs, 1.33 hits, 0.83 Ks, and 0.33 walks per first inning this season.

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