MLB Moneyline Betting

Betting on an MLB moneyline is pretty straightforward as you’re simply picking the winning team. In most cases, there will be a favorite and an underdog listed for each game. Placing a bet on the favorite will offer a lower payout while placing a bet on an underdog will offer a premium payout. The MLB moneyline is typically listed based on the bet required to win $100 if betting on the favorite vs. the potential win for a bet of $100 placed on the underdog.

In the example below, the San Francisco Giants are hosting the Los Angeles Dodgers. The moneyline for this MLB game shows: Los Angeles -225 San Francisco +200.

MLB Baseball Moneyline odds

When reading the listed money line odds, the number in green beside the favored team always begins with a minus (“-“) symbol. The favored team’s number will show the wager amount required to win $100.

The number in green beside the underdog team always begins with a plus (“+”) symbol. The underdog team’s number will show the payout amount for a successful $100 wager.

  • Risk $225 on the Dodgers to win $100
  • Risk $100 on the Giants to win $200

In addition to current records and which team is at home, the starting pitchers typically have a big impact on MLB moneylines. If the ace of the staff is on the hill for the underdog, that might even up the odds a bit between two teams that might seem otherwise a bit mismatched.

Betting MLB Against the Spread

In addition to moneylines, MLB games will also feature a spread or “runline” between two teams. Rather than simply picking a winner, this form of betting features a 1.5-run spread on the final score of any game.

Consider the following example of MLB Spread Betting:

MLB Baseball Run Line Odds

When reading the listed run line odds, the numbers in blue show that you can either bet on the N.Y. Yankees (favored team noted by “-1.5”) to win by 2 or more runs; or bet on the underdog Cleveland Indians (noted by “+1.5”) to win by any amount or lose by only 1 run.

The green numbers show the potential win for either bet. A positive number represents the potential win from a $100 bet, while a negative number represents the wager amount required to win $100. So in the example game above:

  • Bet $100 on the Yankees to win by two or more runs and win $100
  • Bet $150 on the Indians to win or lose by only one run to win $100

Betting the MLB spread can be a great option in certain scenarios. For example, if you expect a favored team to win by several runs, betting the spread will get you better odds than going with the traditional moneyline.

MLB Over/Under Bets

Let’s say two teams seem evenly-matched, but the starting pitchers are not very good, and you expect a high number of runs to be scored. In this instance, you may want to consider betting on the “over/under” total for a MLB game, rather than picking a winner.

An MLB over/under bet involves simply choosing whether you think there will be more total runs scored by both teams, or less total runs, than what is listed on the published line. Here’s how to read a typical MLB over/under line:

MLB Baseball Totals Betting

In the above example, the letters and numbers in blue show that over/under line is set at 9.5 runs. Choosing the “O” options means betting the combined score between the Cincinnati Reds and the Philadelphia Phillies will be 10 or more runs. Choosing the “U” option means betting that the combined score will be 9 runs or less.

The green numbers show the potential win for either bet. A positive number represents the potential win from a $100 bet, while a negative number represents the wager amount required to win $100. So in the example game above:

  • Wager $100 to win $100 if the total number of runs scored by the Phillies and Reds combined is 10 or more
  • Wager $120 to win $100 if the total number of runs scored by the Phillies and Reds combined is 9 or less

With names such as Ted Williams, Jackie Robinson, Roberto Clemente, Nolan Ryan, Walter Johnson, Bob Gibson and Ty Cobb; Baseball and specifically Major League Baseball has a very long history of accomplishments while standing as America’s Favorite Pasttime.

In 1876, 100 years after America’s declaration of independence and only 11 years after the Civil War ends, North America officially adopted the sport of Base Ball. Founded in the formation of the National League of Professional Baseball Clubs (aka the National League), followed by the American League in 1901. The first world series was held in 1903.

The path to becoming officially organized began earlier than 1876. Witnessing a game of baseball among Civil War soldiers was not uncommon during the long conflict. The first official game was held in 1846.

Among the path to becoming a sport with organization and identity, the first professional baseball club was founded in 1871, known then as the Cincinnati Red Stockings and known today as the Cincinnati Reds. Eventually there would be a roster of eight original National League baseball teams; the St Louis Brown Stockings, Philadelphia Athletics, Mutual of New York, Louisville Grays, Hartford Dark Blues, Chicago White Stockings (now the Chicago Cubs), Boston Red Stockings (now the Atlanta Braves) and Cincinnati Red Stockings.

Of all teams, the American League’s New York Yankees have obtained 26 more World Series championship victories since it’s 1903 creation than any other Major League Baseball team.
