MLB NRFI & YRFI Picks Today: Three Sides Beat Fair On Tuesday's 15-Game Board (August 4)
Tuesday, August 4 gives the OddsShopper first-inning odds screen a full 15-game MLB card, 30 NRFI and YRFI sides, and, unlike Sunday's all-pass board, three of them actually clear their fair, no-vig price. That alone makes today's MLB NRFI picks read worth running. But the better story is where the three green rows live, because it isn't random: every one of them comes out of a game where the books are holding almost nothing on the first inning. The pattern has a number attached, it repeats three times, and it tells you exactly which kind of market to hunt in tomorrow. That's the thread this whole read pulls, and it pays off in the hold column below. If the bet type itself is new to you, start with the what is NRFI explainer.
The Quick Answer
Three first-inning sides beat their fair (no-vig) price on Tuesday, August 4: the Chicago White Sox vs. Boston Red Sox YRFI at +104 (fair +102, a +1.2% edge, the board's best), the San Francisco Giants vs. Texas Rangers NRFI at -105 (fair -107, +0.9%), and the Los Angeles Dodgers vs. Chicago Cubs NRFI at +100 (fair -101, +0.7%). The other 27 sides price at or below fair. The full 30-side board, the one number all three value games share, and the two first innings charging nearly four points of vig for the same coin flip are all below.
Tuesday's First-Inning Board: All 30 Sides, Ranked
The frame first, because it decides how you read every row. A positive edge means the best takeable price pays more than the true, no-vig probability says it should. That's value. A negative edge means the price is shorter than fair, and the market is efficient there: no play, whatever the matchup narrative says. Here is the whole 15-game card, best side to worst:

The row worth sitting with is the first one, and not just because it leads the board. The White Sox–Red Sox YRFI at +104 is a plus-money price on a side the devig says is worth +102. Twenty rows further down, the very same game's NRFI shows up at -109 against a fair -102, one of the worst holes on the card. One game, one inning, and the market priced its two halves that differently. That asymmetry is the day's real lesson, so follow it into the hold math.
The Three Value Games Share One Number
Add up the implied probabilities of the two best takeable prices in each game and you get that market's total cost, its hold. Run it on the three games with a green row and the same figure appears three times. White Sox–Red Sox: -109 plus +104 comes to about 101.2% combined. Giants–Rangers: -105 plus +100, about 101.2%. Dodgers–Cubs: +100 plus -105, 101.2% again. Those are the three cheapest first-inning markets on the board, and they are the only three carrying a positive-edge side. That is not a coincidence; it's arithmetic. When the two sides' best prices sum to nearly 100%, almost all of the vig has been shopped away, and one book leaning even slightly the wrong way tips a side over fair. In a market holding 103%+, that same lean just makes a bad price slightly less bad.
Notice what else the three games have in common: in each one, the other side is buried: the White Sox–Red Sox NRFI at -3.4%, the Giants–Rangers YRFI at -3.3%, the Dodgers–Cubs YRFI at -3.1%. The edge didn't appear because the market shrank; the market's margin migrated entirely onto one side, leaving the opposite side selling at better than cost. Which side ended up cheap differs by game (the run-scores side in Chicago, the scoreless side in the other two), so this isn't a "books shade NRFI" story. It's a "thin markets crack, and the devig test tells you which half" story.
Worked Example: What +0.9% On A -105 Actually Pays
Take the Giants–Rangers NRFI and run the two steps the first-inning odds screen runs continuously:
- Best takeable NRFI -105 → a winning $1.05 risk returns $2.05 (stake included), so $1 risked returns about $1.95
- Fair (no-vig) -107 → the market's honest estimate of a scoreless first is 51.7% (107 ÷ 207)
Multiply the $1.95 return by the 51.7% true chance: roughly $1.009 back per dollar risked, the +0.9% printed on the board. Now run the same steps on the Tigers–Mariners YRFI at the bottom of the table: +100 returns $2.00, the fair +109 implies 47.8%, and 2.00 × 0.478 gets back roughly 96 cents per dollar; the board grades it -4.5% on the unrounded true price. Same market type, same night, and the difference between earning a penny and paying a nickel is nothing but the price. That's the entire case for shopping first-inning numbers across books instead of taking whatever your app opens: our how to find +EV bets guide walks the full method.
The through-line: all three positive edges live in 101.2% markets. A thin hold is no promise of value, but on this board it was the precondition for it, and the screen recalculates every game's hold and fair price all afternoon, so a fourth game joining the club shows up the moment it happens.
The Other End: Two Games Charge Full Freight
Here's the promised payoff of the hold column, read from the bottom. The Pirates–Brewers NRFI is quoted at -140 against a fair -127, a -4.1% hole, and its YRFI at +120 against a true +127 gives back nothing at -3.1%: about 103.8% combined, the most expensive first inning on the card alongside Angels–Orioles, where a -110 YRFI on a fair -100 (-4.4%) and a -106 NRFI on a fair +100 (-3.0%) sum to the same 103.8%. Stack that against the 101.2% in the three value games and the spread is the story: on the same Tuesday, in the same market type, having an opinion about one inning costs anywhere from about one point of hold to nearly four. The Angels–Orioles NRFI row is the sharpest single illustration on the board: the devig says that side should pay even money, and the best price available still asks you to lay -106. No first-inning read, however good, survives a toll that size.

A Few Realities Before You Bet NRFI
- A 1.2% Edge Is Real, And It Is Small. The White Sox–Red Sox YRFI at +104 is the best number on the board, and it still loses outright nearly half the time. Edges this size only mean anything across dozens of disciplined spots, never as a promise about one 6:10 PM first inning.
- The Sample Is One Half-Inning. Whether the price is Pirates–Brewers's -140 or Rays–Rockies's +122, the whole bet resolves on six outs or fewer. An edge column is a long-run statement; any single Tuesday is allowed to ignore it completely.
- Lineups And Weather Move These Numbers. These prices were captured Tuesday morning; a scratched starter or a posted lineup can redraw the board. Recheck the screen inside each game's pregame window, from the 5:35 PM opener in Baltimore to the 8:40 PM finales.
- Play Responsibly. Sports betting is for adults 21+ in regulated markets where it is legal. Even a positive-edge price loses often; bet within your means and never chase losses.
FAQ
What does NRFI mean in betting? NRFI stands for No Runs First Inning, a yes/no bet that neither team scores in the first inning, both halves combined. If either team plates a run in the first, NRFI loses and YRFI (Yes Runs First Inning) wins. Nothing after the first inning counts. The MLB betting terms glossary covers the rest of the vocabulary.
What are the best NRFI picks today? On Tuesday, August 4, two NRFI sides clear their fair price: the Giants–Rangers under at -105 (fair -107, +0.9%) and the Dodgers–Cubs under at +100 (fair -101, +0.7%). The board's single best first-inning side is actually a YRFI: White Sox–Red Sox over 0.5 runs at +104 against a true +102, a +1.2% edge.
Is a YRFI at plus money automatically good value? No. Plus money only means the side is an underdog, not that it's mispriced. Tuesday's board quotes the Tigers–Mariners YRFI at +100 when its fair price is +109, which is a -4.5% hole despite the even-money payout. Value is always the takeable price against the no-vig price, never the size of the number.
Why do all three of today's value sides come from low-hold games? Because hold is the market's total margin. When a game's two best prices sum to about 101.2%, as White Sox–Red Sox, Giants–Rangers, and Dodgers–Cubs all do today, books have competed most of the vig away, so one book's lean can push a side past fair. At 103.8% combined, like Pirates–Brewers or Angels–Orioles, the toll swallows any plausible lean before it reaches you.
Bottom Line
Tuesday, August 4 breaks from Sunday's all-pass board: three of 30 sides beat fair, led by the White Sox–Red Sox YRFI at +104 against a true +102, with the Giants–Rangers and Dodgers–Cubs NRFIs close behind. All three came out of 101.2% markets, the three cheapest on the card, while the two games holding 103.8% buried both of their sides. It's as clean a demonstration as this board gives that where the vig sits decides where value can exist before any pitcher or lineup enters the argument. The board found its edges today by finding the thin markets first. That's a repeatable order of operations, and it's the one the screen runs for you every morning.
