What is Expected Value in Golf Betting?
What is Expected Value?
Expected Value (EV) is the mathematical edge you have on a bet. A positive EV (+EV) bet means the true probability of winning is higher than what the sportsbook odds imply.
The Formula
EV = (Probability × Potential Profit) - (1 - Probability) × Stake
Or more simply: if you think a golfer has a 10% chance to win but the odds imply only 5%, you have positive expected value.
Why EV Matters More Than Picking Winners
Most golf bettors focus on picking the winner. But in a 156-player field, even the best golfer wins less than 20% of the time. What matters is whether you're getting fair odds.
How We Calculate EV
We use DataGolf's model probabilities, which are derived from: - Strokes Gained metrics - Course history - Recent form - Field strength adjustments
When their model says a player has a 12% chance to finish top 10, but sportsbooks are offering odds that imply 8%, that's a +EV opportunity.
The Long Game
One +EV bet can still lose. That's variance. But over hundreds of bets, +EV betting is the only sustainable strategy. Track your results, trust the process, and let the math work.
