How We Rank the Best MLB Betting Promos
Not all MLB sportsbook promos are created equal. Some give you real value, while others come with strings attached that make them pretty difficult to turn into real money.
That’s why our team at ats-io.casinowinning.net considers many different factors before recommending any particular offers to our readers. Here are a few things we look at:
- 💰 Bonus Amount: Of course, we would always like the bonus to big. I mean…would you rather have $5 or $100?
- 📜 Fair & Conditions: Have you ever claimed a bonus only to realize the and conditions make it a lot less valuable? Yeah, we hate that too. Our team of experts always checks for reasonable wagering requirements, expiration dates, and any other hidden restrictions/limitations that you should be aware of.
- ⚡ Ease of Use: The best MLB betting promos should be easy to claim and use. You shouldn’t have to jump through too many hoops just to unlock your rewards.
- 🌎 Availability & Eligibility: Some baseball betting promotions are only available in a handful of states. As a result, we make sure to clarify where each offer is currently available and who qualifies for it.
- 🔁 Ongoing vs. One-Time Offers: Some sportsbooks have great bonuses, but very few (or no) ongoing promotions for existing s. We prefer MLB betting sites that continue rewarding players with daily odds boosts, loyalty rewards, no-sweat bets, and other valuable offers.
By considering these factors, we always make sure you’re only getting the best MLB betting promos out there. No fluff, no gimmicks! Just real value to boost your bankroll this baseball season.
Common Types of MLB Sportsbook Bonuses
New to sports betting? Or at least the bonus part of it? Don’t worry! We’ve got you covered. Here are a few of the most common types of MLB betting promotions that you’re likely to encounter:
Bet & Get
These are one of the most popular bonuses at baseball betting sites and apps. Here’s how it works: you place a small qualifying wager (usually just ~$5 or so), and the sportsbook gives you a certain amount of bonus bets—typically much more than the amount you bet in the first place.
Odds Boosts
Odds boosts, on the other hand, increase your potential payout on a certain type of bet, giving you a chance for a bigger reward with no extra risk involved. For example, a sportsbook may boost a player’s home run odds from +200 to +300, meaning you’d win more money for the exact same bet.
Insurance
Also known as “no-sweat bets,” insurance promotions provide a safety net in case your wager isn’t successful. They’ll typically provide a 100% refund in site credit (aka bonus bets) if you lose.
For example, DraftKings commonly offers a no-sweat same game parlay promotion during the MLB season. You build a SGP with 3+ legs included and minimum odds of +400 or longer. If it wins, enjoy your boosted payout. If it loses, you get the full amount back in bonus funds.
Refer A Friend
Finally, most MLB sportsbooks offer a referral bonus when you invite friends to sign up. Your friend just needs to sign up using your ’s unique referral link (or code) and make their first deposit. Then, you’ll both typically get a bonus bet. FanDuel does this, and their referral bonuses are usually $50 each.

Why Do Sportsbooks Offer Baseball Betting Promos?
When I first started betting on the MLB and other popular leagues, I was a bit skeptical of all the bonuses that major sportsbooks were handing out. I figured there had to be some sort of catch I wasn’t seeing.
I mean, why would a sportsbook just give me more money to wager (like with bonus bets) or increase my potential payout (like with odds boosts). But eventually, I figured out what’s really happening, and it made a lot more sense.
Online sportsbooks offer MLB betting promos for one simple reason: competition. There are lots of different betting sites out there, and they are all fighting for your attention.
A huge bonus is a good way to get you in the door initially, and daily odds boosts (for example) will usually keep you coming back to bet throughout the season.
It also has to do with engagement. The baseball season is long (162 games, to be exact), and games are being played almost every day. As a result, betting sites will use promotions to keep bettors active.
Ultimately, sportsbooks aren’t just handing out money for free. They know that once you start betting, you’ll likely stick around and place more wagers. But if you play it smart and take advantage of the offers that actually provide real value, these MLB betting promos can give you an edge over the long run.
Swing for the Fences: Claim the Best MLB Betting Bonuses!
In conclusion, MLB betting promos are a great way to get more bang for your buck.
Extra bonus bets at sign up and daily odds boosts (along with many other types of deals) can provide a whole lot of extra value over the long run. The key is to shop around and find the deals that offer real value by carefully reading the and conditions.
In other words, don’t just settle for the first baseball-related bonus offer you see. Sign up with a couple different sportsbooks so you can pick and choose which deals are worth your time and money.
With the right approach, these promos can help you stretch your bankroll and make the MLB season even more exciting (and hopefully profitable).
Anyways, thanks for stopping by! Feel free to sign up at any of the sportsbooks we’ve mentioned today and claim their latest baseball betting bonuses if you’re interested. Enjoy the season!
