How We Rank Baseball Betting Promos

The way we at TheLines rank sportsbook promos is based on a few factors. For starters, we look at promos that offer the most bonuses to new and returning users. We also factor in promos that have a low risk for bettors. Promos like the Bet $5, Get $150 in Bonus Bets offer a bet365 is a good one because bettors only need to wager $5 for the payout. Even if the initial wager is a loss, bet365 will add funds to keep bettors in on the action.

Some promos would only grant the bonus bets if the wager is a win. Some other proms only return the initial funds as bonus bets if the first wager is a loss. When it comes to MLB sportsbook promos, we factor in all details when we rank them.

The criteria we consider when ranking bonuses are:

• Overall bonus value
• Rollover and playthrough requirements
• Bonus timeframe
• Player investment

One of the standout promo offers is the welcome bonus at Caesar Sportsbook. Bettors can see up to $1,000 returned as bonus bets if their first wager is a loss. Caesars has additional value in their welcome offer as new customers can also earn Tier Credits and Reward Credits. These can be used to redeem hotel stays, game tickets, restaurant vouchers, and more.

We also factor in how much cash investment bettors are required to claim a promo along with the bonus bet expiration date. The multiple promos on offer at DraftKings make them a great value proposition for new users. Allowing bettors to claim multiple promos at once brings a lot of winning opportunities to first-time customers.

How Do MLB Betting Bonuses Work?

When it comes to the best sportsbook promo codes, they were in the same manner as any online purchase. A bettor enters the promo code and sees the bonuses credited to the user’s account. When depositing, a section to enter promo codes will be available for bettors. Bettors must enter the designated promo code at this time, or they miss out on the offer.

For offers that require no promo code, bettors simply opt-in to claim the offer. When exploring a mobile sportsbook, bettors will see banners that say opt in for specific promotions. Click those banners and select the opt-in option to do so.

For bettors in markets that do not have mobile sports betting, there are still options for promos through DFS. Fans can find California sports betting promos for MLB matches via DFS apps for example.

Types Of MLB Bonuses

There are a few notable types of sportsbook bonuses that come from MLB promos. New users will see promos like deposit match bonuses, insurance, bet & get, or a combination of these. These are the most common bonuses that are offered to new users. All users will see promos like odds boosts for MLB matches as well as awarded bonus bets or bet credits.

Bettors should always make a note of the terms and conditions of any promo they accept. Some promos have specific criteria to account for. For example, a promo may only be valid on same game parlays or require wagers have odds no shorter than +400. How each bonus is issued depends on the promo and the sportsbook.

Notable Bonuses

• Odds Boosts: Sportsbooks offer increased potential payouts on wagers. Users must opt-in and use the boost on the designated wager.
• Insurance: Sportsbooks will return the funds of an initial wager if it results in a loss. The returned funds will be issued as bonus bets of equivalent value.
• Bet & Get: Bettors will wager a designated amount and receive bonus bets from sportsbooks. Sometimes, the bonus bets are paid out automatically; other times, they are only distributed if the initial wager wins.
• Profit Boost: Bettors can see a 25% to 30% boost in potential profits when placing a wager.

MLB Betting Tools

When betting on the MLB, it is important for bettors to utilize all their betting tools. In addition to promo codes, bettors should always line shop to find the best odds. This is the major benefit of joining multiple sportsbooks. Bettors can accept multiple welcome promos and also shop the lines to find the best potential payout for each wager.

Fans can find World Series odds comparisons as well as MLB MVP odds comparisons to help bettors find the best odds on the market.
