What Does NRFI Mean in Baseball Betting?

NRFI stands for no runs first inning, an increasingly popular method of wagering on MLB baseball games. As the name suggests, NRFI betting involves whether or not the two teams will combine to score one or more runs during the first inning of the game.

NRFI betting has exploded thanks to the rise in online sports betting, which allows users to place in-game bets with an exhaustive list of props. This bet is particularly exciting because it condenses a traditional over/under wager into a single inning. It's a bet that will yield nearly immediate results (be it negative or positive for the respective bettor).

NFRI Betting Strategies

NRFI betting provides an instant rush of excitement at the start of any MLB game; however, it also involves careful consideration and a well-thought-out strategy.

The most important thing to consider when placing a bet on NFRI is who the starting pitchers are. The stronger the starters, the less likely they are to yield a first-inning run. While the odds are usually fairly close to even (-110), this is not always true.

For instance, let's say you want to bet “no runs first inning” on the Mets vs. Brewers game. This hypothetical matchup features two of the elite arms in the game in Corbin Burnes for Milwaukee and Max Scherzer for the Mets. Because it is a battle of aces, you will likely see NRFI odds that account for this.

NRFI odds:

Yes -165
No +110

You can also examine NRFI betting trends by seeing how offenses have fared at the start of previous games. This can provide valuable insight into whether or not you are getting any value with an NRFI betting line.

YRFI Odds

Since you can bet on no runs to score in the first inning, sportsbooks will also inversely offer odds on YRFI (yes runs first inning). A similar principle applies when sizing up these odds. If the matchup features two potent lineups or a struggling pitcher, then you might want to consider placing a bet on YRFI.
