MLB Parlay Betting Guide

Interested in higher payouts when betting on professional baseball? MLB parlay bets are perfect for you.

Parlay betting in baseball is different from other sports because they don’t use traditional point spread wagering.

The closest thing to point spread wagering is runlines, but these also have attached moneyline odds. Still, baseball parlay bets offer the opportunity to win more money by putting together individual wagers.

In this guide, we will explain how MLB parlays work, show you where to place those parlays, and share top strategies from our experts. Let’s go!

MLB Baseball Parlays Explained

Question mark icon - What is an MLB parlay bet?

MLB parlays allow you to put together two or more individual baseball bets into a single wager.

With parlays, you get better odds and larger payouts but all your selections must win to be able to cash your price.

The reason why baseball parlays are attractive to bettors is that although winning the bets is harder, the payouts are considerably larger if you hit the jackpot.

Top MLB Baseball Parlay Strategies

MLB Parlay Betting Strategies

There are many scenarios where parlays are +EV in baseball and betting on a round-robin or parlay in addition to straight wagers is an excellent strategy.

However, it’s vital to remember that the sportsbooks’ edge increases drastically when adding more teams to a parlay.

For this reason, we recommend players stick with two-team or three-team parlays maximum.

That being said, here are some of the best MLB parlay betting strategies and systems you can follow to better your odds.

Betting Strat #1“Favorite And Under” MLB Parlay Betting System

Favorite and under MLB parlay system

This is a favorite of professional-level bettors and a “system” that has been profitable over the past decade. It’s centered around parlaying the under on the total and home favorites.

The home team always bats last in baseball, and when they have a lead, the game only goes 8.5 innings instead of the standard nine innings.

That half inning is one less time a team goes up to bat, and if things work out with the favorite being ahead, it won’t be played.

This is the best example of an MLB correlated parlay and is particularly valuable when you have teams that are -180 or more at home, with a dominant ace on the mound.

The bet works even better when the opposing team has an average or slightly above-average pitcher on the mound facing an ace.

Remember, we’re not looking for an offensive explosion here. We’re only looking for a large favorite who wins outright and for the total to stay under the oddsmaker’s number.

Betting Strat #2“Two Large Baseball Favorites” parlay Betting System

Two large favorites MLB parlay system

One of the most vital aspects of any baseball betting strategy is finding value in the lines.

Taking massive favorites on straight wagers isn’t necessarily a -EV strategy, but there are plenty of reasons why this should be avoided.

For instance, a -200 favorite has a break-even percentage of 66.67 percent. This means that bettors would need to win this wager about 67% percent of the time to break even.

Yes, just to break even, not even produce a profit. One way to get around paying such a high price for massive favorites is to parlay two teams instead of betting them straight up.

Two Large Favorites Parlay Example

Let’s say we wanted to wager on two large favorites, which are priced at -190 and -210. For us to profit $100 from a winning bet, we need to bet $190 and $210, respectively.

If we parlay these bets together, the payout becomes considerably more attractive. A $100 MLB parlay of these two favorites would return $225, giving us $225 in profits, plus returning our original stake of $100.

Yes, both our bets have to win for this parlay to profit, but we’re risking a lot less, and we’re still looking at a healthy payout.

Betting Strat #3“Large Favorite And Underdog” MLB Parlay System

Two large favorites MLB parlay system

This is an opportunity that arises when you’re incredibly confident in a large moneyline favorite, usually of -180 or more. This is rarely the case, so this isn’t a strategy we would advise using every day.

It’s also important to remember that baseball is a sport with extremely high variance. A fly ball a few inches to the left or right can change an entire game. The long season is to be sure that the cream rises to the top.

Teams can’t fake it over 162 games, but a weak-hitting team can easily beat the best pitcher in the league on a single afternoon.

Placing More Than One Parlay

Let’s say we like the Yankees -200, and two underdogs, such as the Reds +150 and the Giants +150. We can place two 2-team parlays.

Each of these parlays would return $375 on a $100 wager. It includes our original stake of $100, plus $275 in profit.

These bets are excellent because you can lose one of the parlays and still come out ahead nicely with $175 in profits.

Betting Strat #4Circumventing Betting Limits With Baseball Parlays

Circumventing limits with MLB parlays

At most reputable, highly ranked sportsbooks, circumventing betting limits may be frowned upon, but those shops will still pay players if they win their bets.

Let’s say we like the Pittsburgh Pirates (-130) against the Milwaukee Brewers (+120). We’ve maxed out our wager on Pittsburgh as far as straight bets go at a particular sportsbook.

The book won’t take any more money on that side from our account. However, we can get more money down on Pittsburgh if we parlay them with another wager.

As shown using the favorite and under parlay example, bettors can turn a profit using this strategy even if they lose one of their parlays. It also allows them to get more money down on their favorite plays.

Calculating Baseball Parlay odds

MLB Parlay Odds Calculation

Many bettors have a misconception that there is no juice of vigorish charged when betting baseball parlays. This couldn’t be further from the truth.

While baseball parlays offer a fairer calculation than fixed odds parlays, there is still vig charged to players when they force a calculation and move away from fixed odds parlays.

Let’s take a look at an example of a typical baseball market where we want to bet a two-team parlay:

  • Tampa Bay Rays (+180) at Toronto Blue Jays (-200)
  • Cincinnati Reds (+150) at Pittsburgh Pirates (-160)

We have two games here, one American League contest and one from the National League. The Blue Jays are a significant favorite over the Rays at -200, while Pittsburgh is a moderate favorite over the Cincinnati.

How Does A Baseball Parlay Formula Work?

Let’s calculate a parlay $100 two-team parlay on the Reds (+150) and the Jays (-200).

To do this, we need to figure out each leg of the bet in the form of a multiplier or decimal. We offer a betting calculator for doing so, which easily converts all sorts of betting odds.

For this example, we just need to convert the moneyline odds of both teams. The moneyline conversion of the Reds at +150 is 2.5 decimal odds. For Toronto, -200 converts to 1.5 decimal odds.

Doing The Math…

From here, it’s pretty simple. We multiply both our decimal stakes together (1.5*2.5) and get 3.75. We can then subtract our stake, which in decimal form is 1.0 (3.75-1.0=2.75) to get 2.75.

We can then multiply our decimal odds by one hundred (2.75*100= 275) to reach our payout amount of $275. This DOES NOT include our original bet of $100, which will also be returned to us but shows our leaves us with a $275 profit.

Calculating odds for any parlay can be done using this formula, regardless of the number of teams.
