What is Tennis Underdog Betting?

An underdog is a tennis player expected to lose a given tennis match according to the odds. A tennis match is usually between two players, and in every match, there so a perceived underdog and favorite. All bookmakers present the underdog with a plus sign in front of the odds in almost all instances, e.g., +150. On the other side the negative odds, e.g., -210, are reserved for the favorite.

As opposed to the underdog, the favorite is a player who the odds favor to win the match, and usually, their odds have a minus sign before the odds, e.g., -150. Your ROI will be lower than the underdogs when you choose the favorite.

Terms and Conditions about Tennis Underdog Betting

There are no special terms and conditions associated with tennis underdog betting. Pretty much, you will be placing your wager on a player you feel will lose the match. The key thing here is identifying who the underdog player is in a given match. 

Good thing; bettors who think they have uncovered an underdog have numerous betting options to back underdog supremacy in sports betting. The terms and conditions are similar to other types of bets. Of course, each bookie and jurisdiction has specific conditions to be met. So check them out before beginning to bet.

How does Tennis Underdog Betting work?

As stated earlier, you will know an underdog when you see a positive (+) listed in front of the number in American odds. When live betting on a tennis underdog, it means you win that wager when the unfavoured tennis player wins that particular match. A bet on the underdog has higher odds than on the top favorite. When an underdog wins a match, it is usually termed as an upset. One of the biggest sporting upsets in tennis was when Emma Raducanu won the U.S. Open in 2021. 

Betting On Underdog In Tennis Examples

In the 2014 Australian Open, Rafael Nadal was the top dog in Melbourne and as world number one. His return from injury made him easily dismiss Roger Federer in the semi-finals. In the 2014 Australian Open finals, Nadal was the favorite at 1.18 odds to defeat Stan Wawrinka. At the odds of 1.18, you placed a £100 bet on Nadal to win; you would win back a total of £118.0 – plus the original £10 stake. The probability indicates an 84.75% chance of a Nadal victory.

On the other hand, Stan Wawrinka has massive odds of 5.60 – an underdog of the match going into the finals against Nadal. The odds were based on his record – 12 straight defeats against Nadal in all their meetings where Wawrinka had failed even to win a set.  

A £100 bet on a Wawrinka win at odds of 5.60 would return a total of £560, including the original 10-pound stake.  However, the odd indicated that there was only a 17.86% chance that Wawrinka would win the finals. Against all odds, Stan won 2014 Australian Open defeating Nadal in four sets. 

How To Place A Tennis Underdog Bet

Betting on Tennis online is pretty easy. Here is the procedure:

  • Pick a Betting Site. While there are many crypto betting sites, settle on secure, safe, and trustworthy betting site. Above all, your choice site must have the best tennis odds in town. 
  • Sign Up.  Simply create an account, a process that needs your name, email, birth date, and deposit info. Ensure you confirm your account. 
  • Fund your account. Fund your betting account with enough money depending on the available deposit method. While most mobile betting sites accept money, a few accept cryptocurrencies such as Bitcoin. 
  • Place Bet. Once you have enough money, you can begin placing real money wagers. So, choose the tennis tournament/match, tennis player, or bet type, and enter the amount you wish to bet/wager. Confirm your bet and then submit it.

Tennis Bets Covered By The Underdog Category

Here are the common bets you will encounter under the underdog betting category:

Moneyline bets

Money line betting is the most straightforward wager; thus, a top tennis underdog betting strategy. Typically, a Moneyline bet means you place a wager on a tennis player you feel will win the match. In this case, you select the underdog as the one you think will win. You are only paid when the underdog wins; otherwise, you lose. 

Spread bets

A game spread tennis betting means how you will win by some games. For instance, a +4.5 game spread (underdog) means that you are betting on a player to cover +4.5. If, for instance, the player loses 6-4, 6-4, you still win since the payer lost by less than 4.5 total games. 

So, typically, a bookie creates a hypothetical number of games the favored team must beat their opponent. Ideally, you bet on how an individual will perform. 

Tennis Handicap Betting – In tennis handicap betting (spread betting), one player has a distinct advantage while the opponent has a disadvantage/handicap to balance the two players. The favorite wins on most occasions; to mitigate the situation, bettors bet on performance and not the game’s final results. 

Over under

Over under tennis betting means wagering on the total sets in a given match. Bookies usually create a predetermined number of sets that they think the match will last. You can bet on whether there will be more or less a number of sets than the pre-set number of sets. While it may easy, tennis betting tips over under betting might be helpful.

Underdog VS Favourite in Tennis Betting

We all know that every bookmaker may have its own tennis betting rules, but in an aspect they all think the same and that is that an underdog is a player who it is believed that will lose the match. The underdog odds have a plus sign and are usually higher than the favorite’s odds. However, the probability of winning is low – that’s the simplest underdog definition. 

By contrast, the favorite is the player who has the upper hand in a tennis match. Though the player’s odds are small(with a minus sign), the player has a huge probability of winning the match.

Tennis Underdog Betting Explained

There is no best way to bet on tennis, but underdog betting can be very rewarding if you learn to read the odds. However, there are few people who would want to stake their money on the underdogs in certain competitions for the obvious reason that they would lose, even when using the best tennis underdog betting system. However, the rule of the thumb is to avoid betting on the underdogs in grand slams.

This will save you money in the long run. Nonetheless, you can bet on the underdog if you are sure that there is an underlying value in a specific underdog bet. Usually, the difference between the favorite’s ROI and underdog’s ROI in grand slams against other tournaments is extremely significant. 

How Often Do Underdogs Win?

Normally, the chances of an underdog winning are usually very slim, even though some bookies have generous offers and promotions for punters to take advantage of. One study carried out on a data set of  23,190 tennis bets in all ATP tournaments reported that the favorites ROI WA -1.6%, while the ROI for underdogs was -6.3%. This clearly indicates that betting on underdogs comes with massive losses compared to betting on the favorites.

How Underdog is ranked in Tennis Betting

The ranking of the underdogs in tennis considers many factors. However, the key consideration is the performance of a player in question against their opponents. However, the outcomes of the games in which a player is ranked the underdog come with some discrepancies.

When an underdog is established, they are usually given odds higher than their competitor. That is to say, the player is weaker than the opponent and that their chances of winning that match are slim. 

Tennis Odds Explained

Tennis betting odds determine how much you will win from a wager you have placed, no matter the currency you choose, provided the wager is successful. There are three ways to present tennis betting odd:

  • Fractional odds – Popular in the UK and Ireland
  • Decimal odds – Popular in Europe 
  • Moneyline odds – Popular in North America.  

Ideally, betting odds represent the likelihood/chance of a particular event occurring, also called implied probability. If a tennis player is listed at 1.75 to win a match, the odds reflect what the sportsbook believes are the player’s chances of winning the match. 

Recommended Payment Methods for Tennis Underdog Betting

The various tennis fans must be able to deposit and withdraw cash into and out of their betting accounts without much hassle. This is only possible if they select banking options available within their jurisdiction.
