Why First Innings?!

Who doesn’t love a quick first inning prop bet? We noticed how little data was out there to guide smart wagers, so we compiled 20+ seasons of pitch-by-pitch info from the first innings of Major League Baseball games going back to 2005. Curious about how starting pitchers perform in those crucial first at-bats? Our upcoming dashboard will give you everything you need to analyze NRFI and YRFI bets with confidence—from pitcher profiles to ballpark factors and more.
