What does a -2.2% edge mean?

A negative edge of -2.2% means the price (-400) is worse than fair value (-360). 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 80.0% 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 78.3%, which converts to fair odds of -360.

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 looks like a straightforward moneyline play, and it's always fun to back a strong favorite!

Value: the matchup no comparable market consensus to calculate a precise edge here, but the offered price of -400 for a single-leg bet suggests the book is confident in this outcome.
Market context: With no comparable market available, it's hard to tell if this is a particularly generous offer or standard pricing, but it's a very short price for a single outcome.
Status: the matchup is no notable injury or status signal for any players involved.
Social: Reddit has insufficient data for this specific bet, so there isn't a strong public sentiment to consider.
Risk: As a single-leg moneyline, the primary risk is simply the favorite underperforming on the day, which can happen in any match.

Smart insight: the matchup the short odds, this bet's EV is primarily moved by the actual win probability of Alexander Zverev, so any information confirming his strong form going into the match would be key. Similar profile: This is a classic short-odds single-leg moneyline, which typically tracks very closely to market probabilities and offers lower volatility than longer shots. Counter-case: The biggest thing working against this bet is the inherent volatility of tennis; even strong favorites can face unexpected challenges or off days. Live context: the matchup lineups near tip-off. Stake suggestion: the matchup stake.

How this bet was graded

Grade B · 45/100 · Better Off Passing

Alexander Zverev vs Cameron Norrie - Alexander Zverev to win at -400 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 (45/100) 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.
