MLB YRFI Night in America: As Spin Rates Go Down so Does NRFI

Tonight and every Tuesday during the MLB season is NRFI Night in America.

What's an NRFI? It's a baseball betting proposition that stands for "no run first inning," in which you bet there will be zero runs scored in the first frame. (Unless you're betting a YRFI—yes run first inning.)

2021 NRFI record: 110-71 (60.8 percent)

2021 YRFI record: 31-25 (55.4 percent)

It's a YRFI summer. With the warming weather, the Spider Tack ban and batters in the groove of the season, we have reached the no NRFI zone.
