MLB RESEARCH
NRFI / YRFI Research
First-inning research using model probability, team form, starting-pitcher history and scoreless-first offense.
Research note: NRFI/YRFI is one MLB research module alongside Game Research, Hit Rate, H+R+RBI and Strikeouts. Probabilities are model estimates supported by team, starter and offense history.
