What does a -2.3% edge mean?

A negative edge of -2.3% means the price (+50) is worse than fair value (-187). 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 66.7% 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 65.2%, which converts to fair odds of -187.

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 B-grade bet can lose. Size within your bankroll, account for correlation, and don't chase results.

AI breakdown

Verdict: This bet on Denis Yevseyev in Set 1 at an offered price of +50 is an interesting longshot play with an attractive payout.

Value: the matchup there's no consensus market to compare against for a numerical edge, the +50 price offers significant upside if this outcome hits.
Market context: The lack of comparable market consensus means this is a unique offer, making it difficult to assess true value against other books. This is a very thin market.
Status: the matchup is no notable injury signal for this matchup.
Risk: This is a single-leg moneyline bet on a specific set outcome, and tennis can be highly variable.

Smart insight: the matchup the extremely high price, the primary driver for this bet's EV will obviously be the successful completion of the Denis Yevseyev Set 1 win. Similar profile: This fits the profile of a single-leg longshot moneyline play in a niche market, which often presents wider variance in offered prices. Counter-case: The biggest challenge for this bet is the inherent unpredictability of a specific set outcome at such long odds, especially without market consensus to gauge accuracy. Live context: the matchup for any news or reports about Denis Yevseyev before the match starts that could influence performance.

Stake suggestion: the matchup stake.

How this bet was graded

Grade B · 49/100 · Better Off Passing

Set 1 winner: Denis Yevseyev at +50 on Bet365: 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. B (49/100) 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 B-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.
