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 14 starts this season, McDonald has held the first inning scoreless 9 times (64.3% NRFI rate). He's averaging 0.50 runs, 0.71 hits, 0.93 Ks, and 0.50 walks per first inning this season.
Opening Line Analytics combines McDonald's historical stats with real-time lineup data and 10,000-iteration Monte Carlo simulation to generate a combined NRFI probability before every start.
