The Hook

Some matches are about who is better. This one is about how often the underdog gets to steal a set. Alexei Popyrin and Grigor Dimitrov meet at the US Open on August 31, on hard court, with the oddsmakers taking a clear side. Before we get to a pick, let us take apart what the price is actually saying, and whether the market is paying enough for the possibility it is wrong.

The Matchup

Popyrin is a power player. Big first serve, big forehand, and the kind of game that produces short points when it is working. That style is streaky by nature. When the serve lands, he can hold his own service games almost automatically. When it does not, the pressure lands on his return, which is the harder half of his game.

Dimitrov is the more complete shotmaker. A one-handed backhand, variety, and comfort constructing points rather than ending them in two shots. Players like that tend to be more consistent week to week, because they have more than one way to win a point. The odds reflect exactly that reputation: the market trusts the more rounded player over the bigger hitter.

How They Are Priced

The moneyline is simply the bet on who wins the match. Tennis has no point spread, so this is the main market. Dimitrov is priced at -195, which means you would risk $195 to win $100. Popyrin is +180, meaning a $100 bet returns $180 in profit if he wins. The best available price on Popyrin is at Bovada, and that matters. An extra ten cents on an underdog is real money over a season.

Convert those to percentages. A -195 favorite implies roughly a 66 percent chance of winning. A +180 underdog implies roughly 36 percent. Those add up to more than 100 percent because the sportsbook builds in its margin, known as the vig or juice.

The Surface and Conditions

Hard court is the neutral ground of tennis. The bounce is true and the ball moves through the court faster than on clay. In general terms, that rewards two things: free points on serve, and clean first-strike hitting. It also rewards timing, because the predictable bounce lets skilled ball strikers take the ball early. So the surface arguably helps both men here. It gives Popyrin his serve and his forehand. It gives Dimitrov the clean contact his technique depends on.

Where the Value Is

Strip out the vig and the fair line lands near 35 percent for Popyrin and 65 percent for Dimitrov. That means Popyrin at +180 is priced almost exactly at fair, while Dimitrov at -195 is slightly worse than fair. Expected value is just the long-run average return of a bet. You need Popyrin to win more than roughly 36 percent of the time for +180 to profit. Given that a big server on hard court only needs one break per set to change a match, we think that number is fair to slightly generous, and it is the only side here not paying a premium.

The Pick

Popyrin +180, best price at Bovada. Shop it. If a book posts +190, that is the number to take.

The Prediction

We expect a close, serve-heavy match with tight sets and few breaks. Popyrin holds serve well enough to reach a decider and steals it. Popyrin in three sets.
