The Tennis Edge Sportsbooks Still Aren't Pricing Correctly | Presented by ProphetX
10m 19s
This episode explores a strategic betting edge in tennis and other sports where players or teams effectively concede after a significant game state shift, such as being broken twice in a set or falling behind by multiple runs. In men’s tennis, dominant servers like John Isner often give up sets to save energy, especially after a 4-0 or 6-0 lead, making the odds static and exploitable. The key insight is that the scoring system in tennis doesn’t penalize losses in points, so early leads become effectively final. This pattern can also be mirrored in baseball, where teams down by 7+ runs may bring in position players to conserve bullpen arms, triggering high-value bets on the over or home runs. The strategy relies on identifying baseline odds and recognizing behavioral shifts, not just statistical trends. Success depends on price awareness and real-time observation. The host, Isaac Rose Berman, emphasizes that such edges are most effective in high-stakes, energy-intensive sports. The discussion concludes with a promotion for Profit X, a sports prediction market offering better odds through user-to-user trading, ideal for capitalizing on these strategic game state changes.

- Today, we're gonna be looking into a tennis ad.
You might be able to apply into different sports
and you might be able to apply today
and we're doing it with Sharp Better, Isaac Rose Berman.
- Here we go.
- Welcome to the Circles of Channel.
I'm your host, Jacob Remenia.
Please be joined by Isaac Rose Berman,
Sharp Sports Better and Responsible Gaming Advocate
we're recording at Betfash and he wants to go
behind the bet on something he likes to do with tennis,
but we're also gonna discuss again
how we can apply this into different sports.
How long have you been using this?
- Probably three or four years at this point,
maybe even longer and like I said,
yeah, it still comes up sometimes today
both in tennis and other sports.
- So is this something you're consistently looking for
every time the situation sort of arises?
- Yeah, there are certain matches
where it comes up more than others,
but yeah, it can be applied pretty generally
and I think the idea is pretty generalizable as well.
- So let's get into it.
What is the situation at play?
It's a specific game state that we're looking for.
- Yeah, so in tennis you win most of the time
that you serve, obviously.
And so most of the time, especially in men's tennis,
it goes back and forth.
I win my serve, you're when you're serving
and sets are often decided by a single break of serve
when you win, when the other person is serving.
But of course sometimes a player
might go up a lot early in a set
and it's basically they can't come back, right?
Let's say I break you two times and so it's four zero
and so for you to come back and win that set,
you have to break me twice.
And at that point you might as well say,
okay, I'm gonna give up this set
and basically conserve my energy for the next one
because the way tennis scoring works
is not like basketball or football
where the points all add up.
But if I lose the set six zero,
it's the same as me losing a set six two
and you're gonna get the next one.
So basically what you're looking for is instances
where one player will go up a bunch
and then the other player is gonna throw
the end of that set effectively.
And what would happen is sometimes sports books
would keep the game by game prices the same
or they wouldn't adjust for the fact that
the odds that the person who broke twice
is very likely going to break a third time.
I literally just used it in a match
in a match that went on yesterday
where Guillermo Feast was up in the second set up four zero
and then of course you ended up winning the set six zero
which would have been incredibly unlikely at the offset
but because the other guy was like,
yep, might as well just give it up.
So tennis, I mean, it's a grueling sport.
It's very tax on your body.
So if you're, it has to not be the last set as well.
It has to be the first set or something
because you want to conserve your energy
to better equip yourself to win the next set.
That's why this kind of exists there.
So that makes sense.
What is the typical like average break percentage?
How often does a break happen?
About 15 to 20% of the time depending on the players.
Yeah, and so this works best
when the person who has been broken
is someone who wins way more than that.
Like, let's say, you know, 90, maybe 95%.
Right, because of the massive server.
It'll be priced like that.
Exactly. And so if they're,
especially if they're a massive server in general guy
who's like, you know, seven feet tall or whatever,
he very rarely breaks serve and he very rarely gets broken.
And so if he gets broken twice, the set's over.
He's not coming back.
So he might as well, and he knows that.
And he knows that exactly.
So he might as well basically just give it up.
So guys like historically,
Riley O'Pelka, John Isner, Evo Carlovich,
all these guys, like they go down,
they might as well just give up the set
and hope for the next one.
And you said typically this will apply to men's tennis.
Does this not work as well in women's tennis?
It can, it can work for women's,
but women in general hold serve a lot less.
So you're looking like 70,
it's sometimes like 65%.
So even though it can work as well,
A, if you go down two breaks,
you're not out of the set as much.
And B, the baseline percentage of, you know,
breaking is not that high.
So the odds disparity between the game states
is not going to be as much.
So what are the triggers that we should be looking for
when you're placing this?
'Cause this might get priced in at certain spots.
What is the trigger when you know that?
Now I know they're not accounting for this.
Yeah, so of course, basically the baseline odds
at the start of the match, right?
So if your, if a match starts out and you see that,
you know, one guy is priced,
you can get him to break at plus 500 for the entire match, right?
And then if he goes down two breaks,
he's still plus 500, that's it.
So you basically just have to know
what the baseline probability is
and you can either get that from, you know,
knowing his stats in general,
or you can just have seen the odds
early on in the match.
And so I think that's for most people the easiest one
because of course, yeah, sometimes it will be adjusted.
And you know, I've seen people do this
and they're like, you know, betting the guy to break it,
you know, plus 150.
And I'm like, dude, that was plus 700.
It's already baked into the odds.
Obviously you have to make sure
that you're actually getting the right, the good price.
Isaac just said something there
that should always matter to you.
Getting the right price.
That's not just true for this edge,
but it should be true for every bet you place.
And that's exactly why our sponsor, Profit X,
works differently because with Profit X,
you're trading against other users instead of a house.
The hold is thin and prices are often better.
It's America's first sports stated prediction market
available nationwide in the United States,
everywhere except for Nevada.

Are there any players that are specifically ones
that you look for this more often?
They're more likely to give up.
And on the other side, are there players
who just don't give up on any set no matter what?
- Yeah, so it's a good question.
So like I said,
a lot of it is players with really strong serves
and really weak return games.
Oftentimes older players will be more susceptible
because especially when you're talking about a grand slam match
where it's best to fight,
like they really have to conserve their energy more.
And so let's say classic example,
they're up two sets to one.
They go down a two break.
Sometimes even only one break in the fourth set,
you're like, I'm not going to grind this out.
I might as well just give up this set.
And so there, you know,
a bunch of not that crazy examples
where someone will be up two sets to one,
lose the fourth set, six zero,
come back and win the fifth one
because they're conserving their energy.
- If you get it, it doesn't matter.
You don't need to win more games in your opponent,
you just need to win more sets.
- Exactly, it's a weird thing about sort of the way
that the scoring works.
It doesn't matter if you lose six zero or six four versus,
you know, in basketball, you could never do this
because the points all get added up at the end, of course,
makes sense.
Let's talk about how we can apply this
into other sports now,
where in this scenario,
we're heading to the motivation.
What other examples in other sports
do you think kind of line up like this?
- Yes, you're basically looking for game states
where one team is effectively going to give up.
And in most other sports,
you're not going to get a situation like tennis
where they're going to come back later on,
but I think the most obvious example is in baseball.
Let's say, you know, a team goes down seven or eight runs
or something and maybe it's not the most important
game and they want to conserve their bullpen's arms.
And so you start putting position pitchers,
it position players into pitch.
And you know, right when you see that happen,
obviously, you're going to want to bet on the over,
you're going to bet on the other team to score,
you're going to want to bet on every single person
on the other team to start hitting home runs.
All of these things are downstream
of this massive change in game state.
- Yeah, and even the team that's up ate nothing.
If the other team puts into position player,
then they might even throw in someone like that
because they feel like they've already won the game as well.
So they're kind of phoning it in the rest of the way.
Yeah, I think that's a good example.
Can't really think of any other specific giving up
sort of examples, like, you know,
there's pulling the goalie and hockey,
that's not a case of the team giving up.
That's kind of like a last ditch effort.
But just that trigger in baseball,
you're looking for exactly when that position player comes in
because a lot of times the algorithm won't pick that up
for live betting.
But even if you follow baseball enough,
you know kind of the trigger point
where a team is going to put that player
in if something to look out for.
- Yeah, and that's the thing where, you know,
obviously if you see them in the bullpen,
you know, calling it a position player,
then you're great.
But if you think about it,
I mean, the game state change is so massive, right?
Like, I'm not a baseball guy,
but the odds on the over or the odds on a guy to hit a home run,
you're talking like, you know, probably three or four X, right?
So even if you think there's, let's say,
a 50% chance that's going to happen and you place that bet,
especially let's say it's on the over.
So it's not a market where it's like insanely vigged, right?
Maybe the default is, if it doesn't happen,
you're losing the vig, you're losing a few percent,
but if it does happen, now you have a bet that's, you know,
70, 80% EV or something.
And so you actually do often in these instances
want to kind of take a shot.
And so you're guessing that'll happen,
especially since, you know, as you said,
by the time they call them a position player,
oftentimes the odds are going to be tested.
They usually wouldn't even warm up the sky
'cause he's not throwing any heat.
All he just needs to do is lob it into the catcher.
So it's just, you're kind of seeing like 15, nothing gays.
Something crazy like that.
Like just maybe think about getting in ahead of that.
I remember a Blue Jays game earlier in this easy
where that was the case.
But unfortunately, there was no more runs
for like two straight innings after that.
So it doesn't always work, but like you said,
you're putting yourself in a really good position.

Podcast Summary
Key Points:
In tennis, players with dominant serves and weak return games often concede sets after being broken twice, especially when leading 4-0 or 6-0, due to the scoring structure that doesn’t penalize losses in points.
This strategy works best in men's tennis where break percentages are low (15–20%), and players like John Isner or Evgeny Karlovskiy are prone to giving up sets to conserve energy.
The edge is based on baseline odds at match start; if a player is priced at +500 to break serve, and they go down two breaks, the odds remain unchanged, indicating the set is effectively over.
In women’s tennis, the effect is weaker due to higher serve-breaking rates (65–70%), making it less likely for a player to concede after two breaks.
The concept can be applied to other sports like baseball, where teams go down multiple runs and pitch position players to conserve bullpen strength, leading to high-value bets on the over or home runs.
In baseball, the trigger—position player deployment—signals a game state shift with high expected value (EV), even if the outcome isn’t guaranteed.
The strategy requires disciplined price awareness and is most effective when combined with real-time observation of game dynamics.
Profit X is highlighted as a tool offering better odds by trading among users rather than against a house, enabling smarter edge exploitation.

FAQs
A player who goes up significantly early in a set—like being up 4-0—may choose to give up the set to conserve energy, especially if they have a strong serve and are unlikely to come back, as the scoring system doesn't penalize losing by large margins.
Unlike sports where points accumulate, in tennis losing a set 6-0 is equivalent to losing 6-2, so a player who is ahead and unlikely to recover may simply concede, making it strategic to bet on the opponent winning the set.
Players with strong serves and weak return games, such as John Isner, John Isner, or Evgenij Carlovich, are more likely to give up a set after being broken twice due to their high serve consistency and low break probability.
Yes, but less effectively because women generally hold serve more often, and the break probability is higher, making it less likely for a player to give up a set after being broken twice.
The trigger is when a player is down by two breaks early in a set and the odds remain unchanged, indicating the bookmaker hasn't adjusted for the low chance of a comeback, especially if the player has a strong serve.
In baseball, for example, when a team is down by 7+ runs and pulls a position player from the bullpen, it signals a potential 'give-up' scenario, leading to higher odds on the over or a home run bet.
