The market read: Ben Shelton is the favorite at -715 (implied 88% to win), with Tallon Griekspoor at +590 (14%) at the US Open. Best US price at publish; the full pick and reasoning are below.

The Hook

Two aggressive hard court players. One very lopsided price. Tallon Griekspoor and Ben Shelton meet at the US Open on August 31, and the betting market has already made up its mind about who should walk off the court with the win. Our job is not to guess the winner. Our job is to decide whether the number on the board pays you fairly for the risk you take. Those are two different questions, and beginners often confuse them.

The Matchup

Both men make their living by hitting the ball hard and taking time away from the opponent. Shelton is the favorite here by a wide margin, and the odds tell you the market expects him to control the terms of the rallies more often than not. Griekspoor is the type of player who can hurt anyone when his own strike rate is high, which is why he is not priced as a hopeless case. In a match between two forward-pressing styles, the player who holds serve more comfortably usually decides the outcome. That is the whole story here, and the odds suggest the market believes Shelton is the more reliable holder.

How They Are Priced

The moneyline is simply a bet on who wins the match. Tennis has no point spread. A minus number is the favorite, a plus number is the underdog. Shelton is -715, which means you risk 715 dollars to win 100, or 71.50 to win 10. Griekspoor is +590 at BetRivers, meaning 100 risked returns 590 in profit if he wins. Convert those to percentages and you get an implied win chance of roughly 88 percent for Shelton and roughly 14 percent for Griekspoor. Implied win chance is just the odds expressed as a probability. Always shop books. +590 versus a shorter price on the dog is real money over time.

The Surface and Conditions

Hard court is the neutral middle ground of tennis. The bounce is true and predictable, and the ball travels through the court faster than on clay. In general terms, that rewards big serving, early ball striking and players who want short points. Both of these men fit that description, so expect service games to carry heavy weight and expect tiebreaks to be live. Hard court also tends to reduce the value of pure defense, because retrieving alone does not blunt a heavy serve.

Where the Value Is

Strip out the sportsbook's built in margin (called the vig) and the fair prices come out near 86 percent Shelton and 14 percent Griekspoor. That means Griekspoor's fair number is around +605, and the best available price is +590. You are paying slightly above fair for the dog. Expected value simply means what a bet is worth on average if the same situation ran a hundred times. Here there is no fat edge on either side, so this is a small stake spot, not a big one.

The Pick

Ben Shelton to win the match at -715. Keep it small, and only if you cannot find a better number elsewhere.

The Prediction

Shelton serves his way through the tight stretches and wins in straight sets, with at least one tiebreak. Projected scoreline: Shelton in three.
