💰 Best NRFI bets tonight for Thursday

Braves vs. Marlins NRFI (-120) - 6:40 p.m. ET

  • Spencer Strider (2.46 ERA) vs. Sandy Alcantara (3.53 ERA)
  • NRFI records: Braves (21-29) vs. Marlins (24-26)

This could be the largest sample size we've worked with all season long - Sandy's held the Braves to a .204 xBA across 246 plate appearances in his career. Featured here is Austin Riley and Matt Olson, who are both striking out at an average of 35% while hitting .150 against the Marlins ace. On the other side is Strider, who's limited the Marlins to just one hit in 12 at-bats - that'll play as part of our best NRFI bets today.

Athletics vs. Angels NRFI (-110) - 9:38 p.m. ET

  • Luis Severino (4.45 ERA) vs. Jose Soriano (2.41 ERA)
  • NRFI records: Athletics (23-26) vs. Angels (25-25)

We're going back to the well with Soriano here. Even though he's fallen back down to Earth recently, I'm giving him the benefit of the doubt against the Athletics: Nick Kurtz owns just a .184 xBA against him across 10 at-bats, and Tyler Soderstrom is sitting at .266 xBA, which should be enough to get us the three outs we need. While I'm worried about Severino, he's still striking this Angels lineup out at a 25% rate. If we can get through Mike Trout, we should get out of the first frame unscathed.

💡 How I'm betting NRFI picks tonight (May 21)

Follow all of our MLB analysis and expert predictions for baseball season.

No matter the day, I look at how a pitcher matches up specifically to the lineup he's taking on. What's their expected batting average against him? What's their strikeout rate? What's each team's NRFI record? More specifically, how do the top three batters fare against a specific pitcher? These are all thoughts that need to run through your mind before placing a high-variance bet like a NRFI, and slide your units accordingly.


❓ NRFI betting FAQ

What does NRFI mean in baseball betting?

NRFI stands for "No Run First Inning." It's a popular MLB bet that neither team will score in the first inning of a game, and the bet settles after just six outs (three per half-inning).

What does YRFI mean?

YRFI stands for "Yes Run First Inning" - the opposite of an NRFI. This MLB prop bet cashes if there's at least one run by either team in the first inning.

What should I look for when betting NRFIs?

Each team's starting pitcher is the biggest factor in cashing a NRFI bet, but you should also focus on each team's NRFI records (home vs. away) and each lineup's first-inning tendencies. Recent form can also play a bigger role than full-season numbers.,
