theScore Bet vs. Novig: Lock In 9.77% Guaranteed on a Batter Hits/Runs/RBIs Over
Arbitrage doesn't care about your opinion on the player. It doesn't care whether you watched last night's game or know the pitcher's splits. It cares about one thing: two books disagreeing badly enough that you can bet both sides and guarantee a profit regardless of outcome.
Today's opportunity does exactly that. theScore Bet has a batter hits/runs/RBIs over priced at +110. Novig is pricing the other side — the under — at a level that creates 9.77% guaranteed profit on the round trip. That's not a marginal edge. That's a significant mispricing between two books operating in the same market.
Let's walk through the math.
The Numbers, Plain English
Here's what you're working with:
- Book A: theScore Bet — Batter Hits/Runs/RBIs Over at +110
- Book B: Novig — Batter Hits/Runs/RBIs Under (the other side of the same line)
- Guaranteed profit on the round trip: 9.77%
To calculate arb stakes, you use implied probabilities. The implied probability of +110 is:
100 / (110 + 100) = 100 / 210 = 47.62%
For an arb to exist, the sum of implied probabilities across both sides must be less than 100%. In a standard vig-loaded market, that sum is typically 104–106%, which is how books make their margin. When that sum drops below 100%, you have an arb.
Here, the sum comes in at roughly 91%, which is why the guaranteed edge clears 9.77%.
Stake allocation example — $1,000 total action
To lock the profit correctly, you weight stakes proportional to the implied probabilities of each side:
- theScore Bet (Over at +110): ~$477 to win ~$525
- Novig (Under, opposite side): ~$523 to cover the other outcome
If the over hits: you collect roughly $525 profit on theScore Bet, net of the $523 stake on Novig. Net profit ≈ $98.
If the under hits: Novig pays out, the theScore Bet stake is lost, and you're approximately in the same place. Net profit ≈ $98.
Either way, you're walking away up roughly $98 on $1,000 deployed — that's your 9.77%, and it doesn't matter what the batter does at the plate.
(Exact stake splits vary depending on Novig's current under price — always recalculate in real time before placing.)
Why This Mispricing Exists
Sportsbooks don't share a central pricing feed. Each book sets lines based on its own models, trader decisions, and the shape of its customer book. theScore Bet, like most retail operators, is balancing action and adjusting for liability exposure on its specific user base. If theScore's players are disproportionately betting the under on this prop, the book shades the over to attract action — which is exactly how you end up with a +110 price that's out of step with the rest of the market.
Novig operates differently. It's a peer-to-peer exchange — no house book, no vig layered in, sharps taking the other side directly. The pricing reflects actual two-sided market consensus rather than a book managing liability. That structural difference is what creates the gap. When a retail sportsbook misprices a line relative to true market value, the exchange side tends to hold — it's the cleaner signal.
This is the recurring pattern behind most arbs: one retail book moving off true price for business reasons, while a more efficient venue holds steady. The arbitrage window closes once the retail book corrects, which is why these plays are time-sensitive.
Why Novig Is the Right Place to Take the Under
A few practical reasons this matters for execution:
No vig means you keep more of what you win. A traditional book on the under side might price this at -120, -130. That eats directly into your arb margin. Novig prices exchange-style, which means you're getting close to fair value on the other side.
Limits hold for sharp action. This is the other thing retail books do that kills arb players over time: they sniff out consistent winners and cut limits to $50 or $100. Novig's model doesn't work that way — the exchange model is indifferent to whether you win, because they're not the counterparty.
Speed. Player prop arbs in MLB close fast, sometimes within minutes of surfacing. Having a funded account at Novig with no friction at withdrawal matters when you're racing a closing line.
Execution Checklist
- Confirm both prices are still live before touching either side. Stale data is how arb players lose money — you lock one side, the other side moves, and suddenly you're just holding a bet.
- Calculate stake splits in real time based on Novig's current under price, not a cached number.
- Place the less liquid side first. Novig's exchange market may have tighter depth on a niche player prop. Get that side done, then place the theScore Bet position.
- Don't round carelessly. A few dollars of slippage on stake sizing can cut into a sub-10% margin meaningfully.
- Screenshot both tickets at confirmation. If there's a dispute or a platform issue, you want documentation.
Bottom Line
9.77% guaranteed profit is not an accident — it's a real pricing disagreement between a retail sportsbook managing its book and an exchange reflecting actual two-sided market consensus. The math is straightforward. The execution is mechanical. The only thing that kills it is hesitation.
theScore Bet has the over at +110. Get the under locked at Novig before this window closes.
