About NRFI Stats

Through 25 starts this season, Janson Junk has held the first inning scoreless 21 times (84.0% NRFI rate). He's averaging 0.32 runs, 0.76 hits, 0.48 Ks, and 0.28 walks per first inning this season.

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