How to Sign Up for MLB Betting Promos & Bonuses

Signing up for these MLB betting promos and bonuses is simple and only takes a few minutes. These MLB sportsbook promos all have similar sign-up procedures along these lines:

1. Tap on the BET NOW on this page next to the offer or offers you like.

How to Use MLB Betting Promos

Ok, you have signed up for some of these MLB betting promos and are ready to make that first bet. If you haven’t bet on baseball before, you’re in for a treat because there are a million ways to make the best MLB bets today. Because the Texas Rangers are the reigning World Series champs, let’s use them as an example. Of course, you can bet the traditional moneyline, the total or the run line.

The moneyline and totals are self-explanatory, but some bettors may be a bit confused by the run line. Unlike in football and basketball where the spread can range into double digits depending on the strength of the two teams and balances the odds at -110 on both sides, the run line is always set at +1.5 or -1.5 and the odds can vary.

Then, depending on which of the nation’s best online sportsbooks you’re using, you can get as detailed as you like. On BetMGM, you can wager on what happens with Texas starter Nathan Eovaldi’s first pitch (Strike? Ball? In play?) along with a bunch of other signature bets. Caesars Sportsbook, bet365, FanDuel and DraftKings have their own special spins on every game. You can bet on player prop bets – will your favorite player hit a homer, how many strikeouts will your starter get – and team props such as which team leads after five innings or team total runs.

More Markets to Wager on Using MLB Betting Promos & Bonuses

The Los Angeles Dodgers flexed their financial muscle during the offseason to land the biggest free-agent prizes in Shohei Ohtani and Yoshinobu Yamamoto and also acquire pitching ace Tyler Glasnow. These moves have made the Dodgers the betting favorite to win the World Series, which would be their first in a full season since 1988.

If you’re looking to wager on long-range MLB futures this season, then you can click the Futures tab on any of the sports betting apps we have listed and find a gazillion ways to play — even if your favorite team isn’t likely to contend.

For example, we visited the Caesars Sportsbook page before Opening Day and there are 450 different World Series exactas available. A Chicago White Sox fan can get +80000 odds on the Sox beating the Atlanta Braves in the World Series. Hey, New York Mets fans, you want +100000 odds? Simply bet on the Mets to lose to the Tampa Bay Rays in the Fall Classic. These odds and markets will change throughout the season, so be sure to keep checking them.

Your first step in to sign up for some of these MLB betting promos and bonuses. Load up on bonus bets and protected bets and make your best MLB bets today pay off.
