Why First Innings?!
Who doesn’t love a quick first inning prop bet?

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.
