Miami Marlins Odds

Miami Marlins 2025 Season Preview

After returning to the postseason in 2023, the Miami Marlins regressed with a 62-100 record last season. A major reason for that was making eight trades to gut the roster in the name of replenishing the farm system. 

The key point of the 2025 season for the Marlins is to evaluate which prospects are a part of the long-term future. Players like Otto Lopez, Connor Norby, and Victor Mesa Jr. will get plenty of chances to prove themselves. 

Ace pitcher Sandy Alcantara is returning from Tommy John surgery. It might be unrealistic to expect Alcantara to get back to his 2022 NL Cy Young level, but he should still be impactful on the mound. Promising pitching prospect Eury Perez is also slated to come back from Tommy John surgery at some junction this season. 

The NL East is stacked with the Mets, Phillies, and Braves all playoff contenders, so it'll be another difficult season for the inexperienced Marlins.

Betting on the Miami Marlins

Check out below the betting options:

Marlins Spread (Run Line)

When betting on baseball, you’ll be faced with three standard options: the moneyline, over/under and run line.

The run line is a bet on the margin of victory, like a point spread. But because baseball is low scoring, the spread will almost always be -1.5 for the favorite and +1.5 for the underdog. The payouts for each will just be adjusted based on each team’s strength.

Here’s a brief example of a run line for a hypothetical Marlins game:

• Texas Rangers (+1.5)
• Miami Marlins (-1.5)

As shown above, the Marlins are favored by 1.5 runs against the Rangers; the minus sign (-) indicates Miami is the favorite, while a plus sign (+) is used to denote the underdog. Bettors who wanted to back Miami here would be “laying” those 1.5 runs, meaning for their bets to cash the Marlins would need to win by two runs or more. Bettors who selected the Rangers +1.5 would win if Texas won outright or kept a loss to 1 run.

Marlins Moneylines

Many first time bettors are wary of run line bets, especially when riding with the hometown team. In that case, moneyline wagers are often seen as the safer way to go. A moneyline bet is a bet on who wins the game -- no run line involved.

Let’s use the same example from before to understand the moneyline better:

• Texas Rangers +150
• Miami Marlins -180

Just as with run lines, the minus sign (-) signifies a team is favored, while the plus sign (+) means a team is the underdog. The moneyline odds, written in American odds format here, indicate how big or small a favorite that team is, written in increments of $100. For example, to win $100 on the Marlins, a bettor would need to risk $180. On the flip side, a $100 bet on the Rangers would net $150 if they pulled the upset.

Odds can differ from sportsbook to sportsbook, so always make sure you shop for the best line with The Action Network app.

Marlins Over/Unders

Betting on a team to win or cover a run line isn’t the only type of wager allowed on MLB games. Almost all sportsbooks will offer a total on the game, also known as an over/under. This bet is not on the winner of the contest, but on the number of runs the two teams will combine to score; sportsbooks hang a number, and bettors can wager either over or under that total.

If the number for our hypothetical Marlins-Rangers matchup was 8 runs, over bettors would require 9 points or more to cash their tickets, while those who bet the under would need 7 or fewer runs. If the two teams scored exactly 8 runs between them, that bet would push and all wagers would be refunded.

Marlins Props

Some bettors find more entertainment and success betting on more specific outcomes than the result of the game. Prop bets cover a wide market of wagers on player stats, discrete in-game events, and any style of yes/no question. Many props are bets on specific players and their performance, such as betting Otto Lopez over 1.5 hits on a given night, or betting that Sandy Alcantara will strike out over 9.5 batters. Some props can be shorter term, such as betting on the number of runs scored in the first five innings or who will hit a home run. Offerings tend to vary depending on the sportsbook, so use our sportsbook reviews to find the best bet for you.

Marlins Futures

Bettors should shop for the best line to get good odds on Marlins futures bets. Futures are bets that focus on long term outcomes, like the Marlins to win the NL East, win the National League Pennant, win the World Series, or even individual awards like winning league MVP.

How to Bet on the Miami Marlins

Online sports betting was halted on November 22, 2021 in Florida after a court ruling that stated online sports betting (sports betting not taking place directly on Seminole Tribal land) was a violation of the Indian Gaming Regulation Act. However, that's been resolved and Floridians are now currently able to place online sports bets via the Hard Rock Bet app, the only legal option.
