The market read: Karen Khachanov is the favorite at -400 (implied 80% to win), with Roman Andres Burruchaga at +325 (24%) at the US Open. Best US price at publish; the full pick and reasoning are below.

New York Hard Court, One Clear Favorite

The US Open puts every mismatch under a bright light. Karen Khachanov against Roman Andres Burruchaga on hard court is one of those spots where the betting market has already made up its mind. The question for a bettor is not who the market likes. It is whether the price you pay for that opinion still leaves anything on the table. That is where this preview lives.

The Matchup

Khachanov is priced as a big favorite, which in plain terms means the market expects him to control the baseline exchanges and dictate more often than he is dictated to. Burruchaga is the challenger here, the player who needs the match to become messy, long and physical to have a real chance. We are not going to invent a head-to-head history or past results, because none are provided. What the odds imply is simple: sportsbooks see a meaningful gap in level, and they expect the favorite to hold serve regularly enough that the underdog has to create breaks from very little.

How They Are Priced

Khachanov is -400. A minus number is the favorite, and it tells you how much you must risk to win 100 dollars. So -400 means risking 400 to win 100, a profit of 25 percent on your money. That translates to an implied win chance of roughly 80 percent. Implied win chance is just the odds converted into a percentage. Burruchaga is +325. A plus number is the underdog and tells you what a 100 dollar bet returns in profit, so 325 dollars, which converts to about a 24 percent chance. The best available number on Khachanov is -400 at BetOnline.ag. If another book has him at -430, you are paying more for the same outcome. Shopping for the best number is the cheapest edge in betting.

The Surface and Conditions

Hard court is the neutral middle ground. The bounce is consistent and the ball moves through the air faster than on clay, which generally rewards players who serve well, hit through the court and take the first strike after the return. Players who rely on long grinding rallies and heavy defense usually get less reward here than they do on slower dirt. In broad terms, hard court tends to protect the stronger, cleaner ball striker, because there are fewer chances for chaos to level the playing field.

Where the Value Is

Strip out the book's built-in profit margin (the vig) and the fair line lands near 77 percent for Khachanov and 23 percent for Burruchaga. That fair number matters because expected value simply asks whether your price pays more than the market-implied chance deserves. At -400 you are paying a touch above fair, so this is a thin, disciplined favorite play, not a bargain. The underdog at +325 sits slightly under his fair mark, which is why we are not chasing the number just because it looks juicy. The right approach is a small stake at the best available price.

The Pick

Khachanov moneyline, -400 at BetOnline.ag. Small stake, best number only.

The Prediction

Expect Burruchaga to hold his level for a stretch and steal a set if the favorite's first serve dips. Khachanov should still win the serving battle over five sets. Projected scoreline: Khachanov in four, 6-4, 3-6, 6-4, 6-3.
