2021 US Open Tennis Odds & Betting Guide

The US Open has a rich history. Originally known as the U.S. National Championship, one of the most ancient tennis tournaments in the world, it was first held in 1881 in Rhode Island. However, since 1978, it has been held on the hard courts of the USTA center in Queens.

The current version is one of the highly-rated tournaments of the tennis calendar due to its major/Grand Slam status.

Out of the other four Grand Slams — the others being the Australian Open, the French Open, and Wimbledon — it is usually held last, with the tournament beginning on the last Monday of August for two weeks.

The 2021 edition will be the 141st and will begin on August 30. Here’s your guide to betting on the US Open at legal US online betting sites.

NY online sports betting options in 2021

Despite constant calls and negotiations, sports betting in New York is currently restricted to select onsite locations. However, with other states recently passing online sports regulations, and with negotiations in NY proving more and more promising each day, there is some hope that New York could also soon follow suit.

Top US Open betting sites coming to NY

When the legislation does pass and online sports betting becomes legal in New York, here are the top three sites that will be offering betting options on the US Open.

  • DraftKings: They have a wide range of tennis betting options, from unique futures and prop bets to other great live betting options that are available on both their website and their app.
  • FanDuel: With its headquarters in New York, this will be another great online betting option when the legislation does eventually pass. They not only offer great odds and fast payouts on tennis bets but have great perks for their customers as well.
  • BetMGM: This online bookie from the respected MGM Resorts International is another great alternative. They post futures bets for all the grand slam events earlier than most bookies do and have all the tennis markets that you would wish to bet on.

Advantages of betting through a mobile app

Mobile apps have become norms in many parts of our life. The same is true in the betting world. Almost every large online bookmaker has an app that helps ease the mobile betting experience.

All the three sportsbooks mentioned above have apps of their own. These have proved to be highly advantageous in helping bettors keep track of their wagers as they go about their day to day life.

Here are a few of the advantages of betting via apps:

  1. Convenience: As mentioned above, placing bets through apps gives bettors a convenience like never before. You don’t have to schedule a time to walk into a casino to place a bet; you can just do so wherever you are at your own desired time. Plus, mobile apps are designed to be sleek and faster than even websites themselves. This gives users an even greater experience in addition to some added convenience.
  2. You can bet out of state: As long as you’re in a state where the online sportsbook is legally allowed to operate, you can still place all your bets as usual.
  3. Live US Open betting: If you wish to place tennis bets as you watch the Us Open live, such betting apps are the ones that will grant you the best experience. As mentioned, they are made to be super responsive, ensuring that you have a smooth and fast experience. This is especially true in regards to live betting where even a fraction of a second is crucially important.

How do US Open tennis betting lines work?

The lines for the US Open are often set at different times. Futures bets, such as outright tournament winners and other prop bets, are set months in advance of the tournament beginning. Bets and lines on specific matchups, however, are set after the draw has been made.

The draw usually takes place a few days or a week before the tournament begins.

How do tennis futures bets work?

Tennis futures bets work in the same way that other futures bets do. You place your pick before the tournament begins—this can be months or even days before the tournament kicks off—and collect your winnings at the end of the tournament if your pick ends up being correct.

For example, you place a $100 wager on Naomi Osaka to defend her title with the odds listed above. If she were to win the tournament, you would end up collecting a total payout of $800 at the end of the tournament. This would be your profit of $700 plus your initial stake.

However, if someone else were to win the title, your ticket will be marked as a loss.

How do bookmakers set prices and change odds in response to betting?

Tennis odds are set based on a different number of factors. Bookies and oddsmakers take recent seasons and playing form into account. A player who has performed consistently over the past two seasons will be more favored than a player who had a stellar half season a while ago but has been struggling for form ever since.

Because of this, they also take both the ATP and the WTA rankings into account; however, they don’t use the rankings as definite gauging points since some players often have protected rankings to help when they suffer long term injuries.

Also, the type of court to be played on plays a crucial role in gauging a player’s strengths. In the case of the US Open, the tournament is played on hard courts. Players who solely specialize on clay courts will therefore struggle on such courts and will have odds reflective of their performances on hard courts.

Other players are also known to struggle in the US Open while others perform exceptionally well in the tournament. Bookmakers take all this into account when setting odds.

Once the US Open tennis betting odds are set, they change during the season based on how a player performs in different tournaments, or if a player suffers a significant injury. For example, a player may start the year with odds of +1000 to win the US Open in January but may go through a bad run of form that may consequently see his odds increase to +5000 by the time the tournament is set to begin.

What is the best time to place a futures bet on the US Open?

Finding value is always the key to succeeding in betting. If you can find value early on when the lines are set months in advance, then that may be a good option for you/ However, with tennis specifically in mind, it’s best to see how certain players perform as the season goes on. This will then give you a good indication of how certain players are expected to perform on the grandest of stages.

Placing a futures bet on the Us Open two to three months in advance, therefore, maybe the best time to place a futures bet. Since the competition starts at the end of August, this would mean that you place your futures wager around June/July, directly in the middle of the tennis season. At that time, you’d have more than enough information to help you settle on a calculated futures bet.

Different bet types in tennis 

Other than futures bets, there are also a different number of bet types that you can place in tennis matches. Some of these are:

  • Outright match winner: You bet on who is going to win the match between the two players.
  • Over/Under for games: Here, you bet on whether the total number of games in the match will be over/under the line set by the bookies. For example, if the line is set at 18.5 games and you place an over on this line, the total number of games in the match has to be 19 or more for you to win. Therefore, a match with a score of 6-4 3-6 6-1 would be enough to guarantee that you win the bet.
  • Set winner: In this type of bet, you pick a specific player to win a certain set. For example, you can place a bet on Novak Djokovic to specifically win the first set of his upcoming match. Your ticket will then be decided on whether Djokovic wins the first set, and no other set will be taken into consideration with this bet. So Djokovic can win the first set and lose the match, but you’ll still win your bet because your predicted pick came true.
  • Total number of sets: This specifically targets the number of sets that are expected in a match. For men’s Grand Slam singles matches, which are a best-of-five-sets affair, the two options are usually whether the match will have three sets or 4+ sets.
  • Women’s Grand Slam singles matches, on the other hand, have a maximum of three sets. In this, the two options are whether the match will have two or three sets.
  • Game/Set spreads: These types of bets work in the same way that point spread bets do. A handicap is often applied and you bet on whether the favorite will be able to overcome the handicap or whether the underdog will be able to hold on to the advantage that the bookies have given to them.

Live tennis betting on the US Open

If you’re keeping tabs on the matches at the US Open, you may also fancy a bet as you watch the action. Live betting in tennis is simple. Bookies often offer a variation of earlier markets—match winner, set winner, o/u games, etc. — but the live odds will often be reflective of how the match is going.

Most sportsbooks and other live score websites and apps will also offer a live play by play coverage, so you’ll always have accurate and up to date information when you go to place a bet, even if you aren’t able to watch the match.

So if you missed out on an option and still want to place it as the match is going on, you’ll always have the ability to do so.

You have to keep in mind that you need to place your bet before a point starts. Once it does so, most of the options will be suspended until that point is decided. The odds will also frequently fluctuate based on how each point is played out.

Top tennis betting tips for the US Open

When betting on the US Open, here are the top wagering tips to keep in mind:

1. Ensure that you know all the rules of the sport

It is crucially important that you’re aware of all of the rules that tennis has, from serving and returning to potential penalties. This will help guide your decision making when you’re handicapping bets so that you don’t blindly bet on something that you’re unaware of.

2. The value is in the underdog

As is common knowledge in sports betting, the favorites don’t always win. Add to that the fact that underdogs are always better priced than their opposing counterparts. With major upsets in recent grand slams, backing the underdog seems like a good investment option to take.

One great way of maximizing an underdog’s value is by picking prop bets on overlooked players to reach the latter stages of the tournament. Some bookies offer markets such as “Player X to make it to the fourth round” which can be good hunting grounds if you think that an overlooked player with high odds is bound to get past an easy draw.

3. Always keep playing styles in mind

The form is a good indicator of how you’d expect a player to perform but so is playing style, which is often overlooked by many bettors. A player may be ranked high in the ATP rankings and maybe coming into a matchup in some great form, but may come up against a player whose playing style completely neutralizes his own.

4. Heed to the draw

If you’re placing a futures bet right before the tournament is about to begin, you have the added advantage of looking at the tournament’s draw. This can show you potential matchups and opponents that a player may face, giving you a rough idea of whether their path to the title is an easy or hard one.

5. Adjust for doubles betting

A lot of the principles of singles betting also apply to doubles betting. However, in doubles betting, other factors such as the length of playing time between doubles partners, i.e. chemistry, and rankings play more significant roles and should be factors that tennis bettors consider before placing a bet.

What happens to a tennis bet if a player retires?

However, if you picked a moneyline wager (outright match winner), the outcome of your bet will depend on your bookie. Some bookies state that as long as the ball has been served, the bet will not be voided. Others stipulate that either one or two sets must be played for the bet to stand. While others will void it as they only grade bets on if a match is completed.
