Online MLB Betting

Founded in 1903, MLB has 30 teams split evenly across the American League and National League. Each team plays 162 games during the regular season before the AL and NL playoffs begin to determine which team from each league will be headed to the World Series. The World Series is a seven-game series played between the two pennant winners to determine the world champion.

The best safe and legal MLB betting sites like Unibet NJ include feature-rich markets which allow bettors to consider the diverse elements of each MLB game. Knowing how to bet on MLB games, how to look for the best MLB betting lines and where to find the best MLB betting sites is important to your online MLB betting experience.

MLB Betting Lines

Knowing how to bet on MLB games comes down to understanding run lines, moneylines and the over-under runs number set by the bookmaker.

Run Lines

Instead of the point spread as used in other sports, MLB betting uses the run line, which is essentially the same thing. The run line is a form of handicap betting—with a 1.5 line the usual offering from MLB betting sites—that lets you back the favorite to win by two runs or more or place a bet on the underdog losing by one run or winning the game outright.

When looking at a run line, the team with the minus symbol (-) is the favorite and the team with the plus symbol (+) is the underdog. An example:

Dodgers -1.5 | Phillies +1.5


The moneyline on MLB games is similar to other sports. It features two numbers that determine winnings for bets placed on either team to win outright. The favorite is noted by the negative number and is the dollar amount one bets in order to win $100. The underdog is noted by the positive number and is the dollar amount one wins on a $100 bet.

Dodgers -250 | Phillies +125

To win $100 on the Dodgers, a bettor must place a $200 stake on them to win the game outright. For bets on the Phillies, a $100 bet returns $125 if the underdog pulls the upset.


The over/under runs is a bet placed on the total number of runs scored by both teams. An over/under runs bet doesn’t have anything to do with who wins the game. It only has to do with whether the combined score is over or under the over/under runs number set by the bookmaker.

Dodgers vs. Phillies | O/U 7.5

A 7.5 over/under runs pays out for the over if the two teams score over 7.5 runs (example: Dodgers 7, Phillies 5). It pays out for the under if the teams score less than that (example: Dodgers 3, Phillies 1).
