Betting on US Open 2020

The popular hard court tennis championship is counting a few days before its much-anticipated start. No wonder it is the talk of the town within tennis betting circles. It also comes as no surprise that a growing number of online bookmakers come forward with exciting US Open betting offers.

Betting on US Open 2020, though, can be quite challenging if you don’t know at least the basics. Now, if you want to be able to spot and benefit from the, admittedly, enticing Open betting deals, simply read on.

We give you US Open tips to help identify the best US Open odds (and not only) and bet on US Open with high chances of winning. Hopefully, betting on US Open will be a walk in the park this year after that!

Want to bet on US Open and stand a good chance of getting yourself a winning bet? The US Open odds are among the first things you definitely need to know. Combine your acquired knowledge with some clever tricks and US Open tips and boost your earning potential. Here are some notes to make betting on US Open a tad easier (and more fun) for you.

US Open Odds

Betting on the US Open can be done either during or before the match. You may even have the opportunity to watch live streams of the US Open before you lay a wager with in-play betting. In this case, expect to find from standard markets (i.e., total games and match-winner) to in-running set scores.

Remember, though, that the live betting-related odds reflect the chances a player has of winning and adjust as the match is played.

The most popular bet, though, is on who will win the match and is placed before the match begins. Other much-favoured pre-match wagers involve over/under bets on total faults and aces and how long the match will last before we have a winner.

You will be able to view the available odds on matches as soon as the players (opponents) are determined. Right after the draw is set, the first round odds appear. Once the first round ends, the second round odds become available and so on.

Now, you may notice that some odds take longer to appear (i.e., after a player’s injury before a new round). This is because online bookies are waiting for the injury report to be released before they determine their lines.

Finally, reading and comparing the odds are certainly must-know things. Just keep in mind that the higher the number is, the less a player is considered a favourite (and the other way around, of course).

You will notice, however, that the same player is given different odds from various outlets and online bookmakers. In this case, pay attention to the payout. Obviously, selecting a bookmaker’s site that pays you more on your wager(s) should be the go-to option here.

US Open Tips

Most bookies’ sites offer outright odds for the final Grand Slam of the year months in advance. However, the closer we get to the start date, the more markets become available. The majority of them, though, are priced up after the main draw before the event.

Before you start betting on the US Open 2020 championship, bear in mind the following:

  • Court speeds
  • Stamina and strength
  • Type of surface (i.e., many major servers find it challenging to play on a lower surface).
  • Players’ fitness level.

Tennis Betting Odds Explained

As part this how to bet on tennis article, here is a look at tennis odds formats:

Ways of Expressing Odds: Fractional, Decimal and Moneyline

There are a number of odds formats that are mainly based on geography. The UK, the rest of Europe and the United States have a default expression of odds. Here are the three most common betting odds and the way that an implied probability of 50% is expressed:

  • Decimal (UK): 1/1.
  • Fractional (Europe): 2.00
  • Moneyline (USA): +100

On any sportsbook, customers can change the default tennis betting odds format. There are also a number of Asian odds formats but these rarely appear on UK, Europe and US-facing sites.

How Tennis Betting Odds Work

To illustrate odds, let’s assume a men’s match in which the betting market in fractional odds is as follows:

  • Roger Federer 1/2 (66.66% of the market)
  • Rafael Nadal 6/4 (40.00% of the market).

The theoretical profit margin in this match is 6.66% but the bookmaker is not certain to make a profit because most bets at these tennis odds could be on one player. Here is how bookmakers settle bets in each format and both outcomes:

Federer Wins

Fractional: £100 x 1 + (1 /2) = £150.
Decimal: £100 x 1.5 = £150.
Moneyline: £100 x -200 = £150.

Nadal Wins

Fractional: £100 x 1 + (6 /4) = £250.
Decimal: £100 x 2.5 = £250.
Moneyline: £100 x +150 = £250.

Tennis Betting Markets

Bookmakers issue odds in three types of market: pre-match, in-play and ante-post. Markets available for tournaments are on the following tours: ATP (men) and WTA(women), Challenger and International Tennis Federation (ITF). This how-to bet on tennis article now describes the main markets for tennis betting which fall within one or more of the tennis betting categories:

Betting on Matches

The match-winner market is the most popular in tennis betting. In regular tournaments, men and women play over the best of three sets. Men’s matches in the Grand Slam tournaments and Davis Cup are the best of five sets.

In most cases, there is a definite outcome to a tennis match. However, on rare occasions a player retires because of injury bookmakers have specific rules.

Betting on Outright Tournament Winner

This is an ante-post market and involves predicting the winner of a tournament. Bets can be a win and each way and standard place terms apply. Bookmakers update this market after each match and bettors can back a player to win from before the tournament begins up to the final. The market becomes win only at the semi-final stage when there are only four potential winners.

Betting on Sets

When looking at a guide to bet on tennis, readers should consider set betting which is similar to game betting. The odds are for the total number of sets or a total number of games in a set or the match.

In a match, in a regular tournament, the potential outcomes are two or three sets. In a men’s Grand Slam event and the Davis Cup, the potential outcomes are three, four or five sets.

Betting on Tennis Match Handicaps

A handicap is a start given to the underdog when there is a strong favourite. The match-winner tennis odds are too low to attract many bets. Bookmakers issue a total games handicap to generate betting interest on both options.

They express the handicap in half games to eliminate the tie and void bets. Tennis handicaps are two-way markets and are subject to tennis tips.

Betting on Tennis Under/Overs

This is a market for the total number of games. Some bookmakers quite odds for a number of bands of games. However, most quote odds for the total being over or under a specified number.

The quote is also in half games so there are a definite outcome and no potential for a tie. There is a similar but less popular market for over or under a quoted number of sets.

Other Tennis Bets

This guide to how to bet on tennis identifies the following other tennis bets:

  • Match correct score in sets.
  • Set correct score in sets.
  • Game score in points.
  • Asian handicaps.
  • A number of breaks.
  • First and second set betting.
  • Race to a specified number of points

Tennis tips are available for some of these markets.
