What does a -2.2% edge mean?

A negative edge of -2.2% means the price (+45146) is worse than fair value (+46164). You can still win, but the long-run math is against you.

Does a positive edge mean the bet is likely to win?

No. The market still implies about a 0.2% chance this hits at the offered odds. A +EV bet pays more than its true probability warrants — most +EV bets at long odds still lose individually.

How are fair odds calculated?

Sportsbook prices on the same market are de-vigged and averaged to estimate a true win probability. Using the available market price, we estimate 0.2%, which converts to fair odds of +46164.

Why does this grade differ from the sportsbook's advertised lift?

Books quote lifts vs their own original line, which already includes margin. We compare the price to a vig-free consensus, so an advertised lift can still grade poorly if the underlying line was inflated.

Should I bet every bet that grades well?

Grading is a price-quality signal, not a guarantee. Even a F-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This four-leg home run parlay offers slightly negative expected value compared to fair odds.

Market context: At +45146, the boost is priced below the estimated fair odds by AiOddsLab.
Status: the matchup is no notable injury signal for any listed player.
Risk: This is a four-leg parlay involving home runs, which inherently carries significant multi-leg parlay variance due to the low probability of each individual event.

Smart insight: The overall EV of this bet is highly sensitive to the true individual home run probabilities of Junior Caminero, Elly De La Cruz, Ian Happ, and Gunnar Henderson. Similar profile: the matchup same-game parlays featuring longshot individual player props, which frequently exhibit negative EV due to compounded probabilities and sportsbook margins. Counter-case: The boost's price is already slightly worse than the devigged fair odds, indicating a lack of true edge. Live context: the matchup lineups near tip-off.

Recommendation: Pass.

How this bet was graded

Grade F · 38/100 · Better Off Passing

4 leg parlay at +45146 on FanDuel (4 legs): we couldn't match this slip to enough comparable market prices to compute a trustworthy consensus fair value, so no edge % is shown — anything we'd print would just echo the book's own vig. The grade leans on price lift vs the original (+0.0%), leg count, and variance. Treat it as directional.

Frequently asked questions

Why isn't an edge % shown?

We couldn't match this slip to enough comparable market prices to compute a trustworthy fair value. Rather than show a number derived from the offered price itself (which would just echo the book's vig), we leave the edge unstated. The grade still reflects price lift vs the original, variance, and confidence.

Does the grade still mean something?

Yes. F (38/100) is built from the price lift, leg count, variance, and any verified context signals — it's directional. Treat it as a sanity check, not a precise EV figure.

Should I bet every A-grade ticket?

Grading is a price-quality signal, not a prediction. Even an F-grade ticket can lose. Size within your bankroll, account for correlation between legs, and use Inside Angles above to spot factors the price hasn't absorbed yet.
