1. Fanatics Sportsbook MLB Promos

Sign up for Fanatics Sportsbook via one of these MLB promos:

The Fanatics Sportsbook promo code is perfect for MLB betting. In addition to FanCash, these promos will unlock perks such as:

• FanCash Rewards: Every MLB bet earns "FanCash" (typically 1% on straights, 3% on parlays, and up to 5% on Same Game Parlays). You can spend this credit as bonus bets or use it to buy official MLB jerseys and hats at the Fanatics merch store.
• "Fair Play" Injury Protection: Fanatics Sportsbook has a unique policy that voids player prop wagers (like "Aaron Judge to hit a HR") if the player leaves the game due to injury within a specific timeframe. Fair Play is valid on pitchers and batters.
• In-Depth MLB Markets: Beyond standard moneylines, they offer a deep menu of baseball-specific props, including: pitcher strikeouts, innings pitched, first 5 innings (F5), and batter props such as total bases/hits/home runs.
• "Squad Bets": A new feature that lets you build a parlay based on collective achievements (e.g., "Any 3 players from the Braves to combine for 5+ hits") rather than needing every individual leg to hit perfectly.
• Niche Baseball Coverage: Unlike some competitors, Fanatics often carries odds for Triple-A, Pacific Coast League, and international baseball leagues, making it a haven for true diamond junkies.
• High-Speed Live Betting: The app is optimized for the "pitch-by-pitch" nature of baseball, with odds that update quickly for live inning totals and result-of-at-bat wagers.

Step 3: Follow the terms and conditions. Here you need to make sure you follow all the terms and conditions of your bonus offer correctly. Sometimes you'll need to input one of our promo codes, and sometimes you won't. But it is important to read the terms and conditions at the sportsbook you're using to make sure you get your sign up bonus.

Step 4: Deposit. The next step is usually to make your first deposit. This is when following the terms and conditions is important, because a lot of sportsbooks have deposit minimums of around $5 or $10 to get the new user bonus.

Types of Promos on the Best MLB Sportsbooks

The fun of picking between the best MLB betting promos is that you have plenty of options between types of bonuses. Here are some examples of what you may see when you use any of our best MLB betting promos on baseball bets.

• Bonus Bets: The bonus bets are a typical promo offer given to new users by a lot of sportsbooks. They usually are given if a new user places a first time wager, and have an expiration on when they can be used. 
• Deposit Match: A deposit match is when a sportsbook matches your first deposit with some kind of bonus credits. It is a good way to get a "2-for-1" type of deal.
• No Sweat Bets: No sweat bets are used often as well, and are simply how you can get your first wager back to you if you lose it. This is another type of "2-for-1" offer, but it is only given if your first wager loses.
• Daily Boosts: Daily promo boosts are a big part of existing user promos on pretty much every popular sportsbook. They are a great way to get better odds on popular athletes or sporting events each day, so we recommend checking those out on your favorite sportsbooks.
• Profit Boosts: A profit boost is usually given as tokens to use either as a new user offer or existing promos. These profit boosts can be added to bets or parlays to juice up the odds in your bet.
• Referral Bonuses: Sportsbooks have referral bonuses that you can share with your friends too. These help you and your friends get bonus offers back from the sportsbook just from sharing a certain code together.
• Rewards Programs: These aren't at all the sportsbooks we use, but rewards programs are a great incentive to staying consistent with a sportsbook. Fanatics FanCash is a great example of this. FanCash is earned on every bet at Fanatics Sportsbook, and you can use that later on as bonus credits in bets or in the Fanatics store.
