Tennis Betting Strategy: Accumulators and Over/Under Total Number of Games

Tennis Betting Strategy: Accumulators and Over/Under Total Number of Games
© PA

In the early rounds of tennis tournaments, there are often encounters which appear – on paper, at least – to be somewhat one-sided.

Instead of taking prohibitive odds on a fancied player to win a match, tennis bettors visit tennis betting sites to combine several favourites into an accumulator.

Another tennis betting strategy is to target the over/under game market, where you can bet on the total number of games in a tennis match.

Accas, as they are often called, are a staple of football betting and you'll find they are also among the most popular picks when searching for tennis betting tips.

The over/under market - which is usually entitled 'Over/Under Total Number of Games' - is also definitely one to consider. Here, we dive into tennis betting strategy and take a look at both in detail.

Accumulator Betting

Tennis accumulator betting does exactly what it says on the tin. You pick a number of players to win their respective matches and they all have to win for you to land the accumulator bet.

As an example, there were five matches completed on the first day of the main draw at the ATP 500 at Eastbourne in 2019. The favourites were priced up as follows: 2/5, 4/5, 33/50, 6/10, 3/10, with the accumulator bet on all five favourites coming to 15/2.

But the player priced at 4/5 was James Millman, who went down in three sets to Fernando Verdasco, so the bet lost. There was little between them in that match but if you employed a safer strategy, like only backing players priced 3/5 or shorter, you were left with a treble paying out at accumulator odds of 19/10 (which did win).

Of course, you can tailor your tennis accumulator to include players you think are overpriced and exclude those you deem suspect on the surface or out of form. But the risk, as with all accas, is that one player lets you down. Some of the best bookmakers offer acca insurance on tennis accumulator betting. They will return the value of your stake as a free bet if one leg lets you down, although your acca usually must have a minimum of four/five legs and combined odds of at least 3/1.

Some online betting sites also offer lucrative bonuses on winning accumulators. bet365 will pay a bonus ranging from 5% for a winning double or treble through to 20% for a six-fold all the way to 50% for a 12-fold or greater.

Tennis Betting Over/Under Market

Tennis betting over/under is also labelled simply as total games betting at many online betting sites. You simply bet on whether a match will last over or under a specified number of games. Each set can have a maximum of 13 games (the tiebreak being the 13th game) unless it is a decider in certain Grand Slam events when a margin of two clear games is required to secure victory.

With service holds easier and more common in the men’s game, a match between two fairly evenly matched players will result in a threshold figure of either 23.5 or 24.5 for a best-of-three encounter. In the women’s game, where breaks are more common, this number drops to 20.5 or 21.5. The odds for overs and unders are usually initially priced up as 17/20 for each side and these will change according to bet volumes.

Some new betting sites will offer alternative under/over game tennis thresholds with bigger price differentials. So a match with 17/20 either side for 23.5 games may be priced up as 33/100 for over 20.5 games and 2/1 for under 20.5 games.

In-play betting kicks off at the start of the match with more threshold options usually becoming available. As the match progresses, these odds change and it is simple to adjust your staking plan based on how you see the match going. If a player is getting on top and looks to be on the way to a quick win, it might be profitable to bet ‘Unders’. Similarly, if it looks like a tight encounter, ‘Overs’ will be the way forward.

Matches going to three sets are usually fatal to ‘Unders’ bets. And the more one-sided the match is on paper, the fewer games should - theoretically - be required to decide the outcome.
