Baseball betting guide: Understanding the basics

Before you place a wager, you’ll need to know the basics. And as one the best baseball betting guides, we deliver exactly that. Here are the most common ways to bet on baseball:

TermMeaning
MoneylineBetting on which team will win the game outright, no point spread involved
Run LineBaseball’s version of a point spread; usually set at -1.5/+1.5 runs
Over/Under (Total)Betting whether the total combined runs scored will be over or under a line
ParlaysCombining two or more bets for a higher payout (but all must win)

Moneyline

The simplest type of bet where you get to pick who wins and not worrying about margins or total runs. For example, in a match between Yankees -130 vs Red Sox +110. If you bet on the Yankees, you need to stake $130 to win $100. If you bet on the Red Sox, a $100 bet would win you $110. We’ll explain the odds in detail in the next section.

Run Line

Here you get to predict the margin of victory. It’s like the point spread in football, but for baseball and usually set at 1.5 runs, meaning the favorite must win by 2 or more runs and underdog must lose by 1 run or win the game outright. It ramps up the fun, especially in matchups where one team is heavily favored.

Totals (Over/Under)

Here, you’re betting on the combined number of runs scored by both teams, not who wins. For instance, in Over/Under 8.5 Runs, you bet whether the final score will total over 8.5 or under 8.5 runs.

You aren’t just limited to who wins or loses as baseball gives you loads of markets, that’s different aspects of the game you can bet on. These include the number of home runs, strikeouts, player props, and even who will score first. Player props which are individual achievements like a pitcher’s strikeouts are getting bigger in recent times, so they’re a great entry point if you’re still figuring out how to bet on baseball.

All you need to know about Baseball betting lines explained

Now let’s get into baseball betting lines. Betting lines are the set odds and point spreads a sportsbook offers for a game. They tell you things like which team is favored, how much you can win if you bet correctly, the expected margin of victory for Run Line bets and projected total runs scored for Totals.

Here’s what you’ll usually see for a baseball game just as an example:

TeamMoneylineRun lineTotal
Yankees-1351.5 (+140)Over 8.5 (-110)
Red Sox+115+1.5 (-160)Under 8.5 (-110)

Moneyline shows the odds to win, while Run line shows the spread (1.5) and odds while Total shows the projected combined score. We always suggest comparing lines across a few sportsbooks because even tiny differences in odds can make a big difference over a season. You can check our online betting guides here on GameChampions for how to spot the best value odds.

What are Baseball odds?

Let’s quickly get baseball odds explained. In the U.S., odds are usually displayed as positive (+) and negative (-) numbers:

  • Negative odds (like -135) show how much you need to stake to win $100
  • Positive odds (like +150) show how much you can win from a $100 risk

Some sportsbooks also let you view odds in decimal or fractional formats, but for baseball betting, American odds are the most common and what you’ll usually see. For example, Dodgers -150 means you’ll need to bet $150 to win $100. And in Padres +130, you need to bet $100 to win $130.

Bear in mind that odds aren’t just payout calculators as they also reveal probability. The more negative the odds, the higher the implied probability that the team wins. If you’re also interested in horse betting, our how to bet on horses guides have some really great tips on spotting the best odds.

The best baseball betting strategies you need

Now here’s the fun part, the best strategies to put into play if you want to move from guessing to placing more strategic wagers. Just bear in mind that even the best strategies don’t work all of the time as outcomes are uncontrollable. That said, here are a few tips that can help.

⚾ Pitching Matchups

Pitchers control baseball games. Always research the starting pitchers for each game. Check if they are left-handed or right-handed, how many innings can they go and if they’re also good at suppressing runs. A strong starting pitcher can totally change how you approach a bet.

📉 Target Underdogs with Value

Since baseball is low scoring compared betting on basketball or football, underdog wins happen surprisingly often. Look for underdogs offering +120 or higher if they have a good pitcher or a strong bullpen.

⚠️ Be a Bit Wary of Heavy Favorites

Sometimes even the best teams lose 50+ games a season. Don’t go all in on heavy favorites like -250 unless they’re good reasons to back it up, and even then, tread carefully.

☁️ Weather Matters

Yep, wind blowing out can lead to more home runs and higher scores. While wind blowing in can suppress runs. Always check the weather report for the stadium before betting the Over/Under.

📈 Track Line Movements

If you see the line move significantly before the first pitch, it sometimes signals high rollers pushing the market. Remember to have fun while at it and remember nothing works 100% of the time.

Are stats and team analysis important in baseball betting?

Straight answer, yes. Baseball is one of sports where stats matter all the time, you just have to know how to use them to your advantage. You should be on the lookout for numbers like a pitcher’s ERA, that is Earned Run Average, a team’s batting average, home/away splits, and bullpen strength to spot trends that the odds alone may not reveal.

The Pitcher’s ERA tells you how many runs a pitcher gives up on average, the lower, the better. A team’s batting average will point out how often their players are hitting the ball successfully. A high average usually means more chances to score. Then home/away splits will always show if a team performs better at home or struggles more on the road, which can swing results.

And bullpen strength measures how good a team’s relief pitchers are at closing out games, which is crucial in tight matchups. That said, being a part of an active betting community lets you pick up even more useful insights from others who dig into these stats daily.

The best online betting sites to stay connected

Baseball betting thrives on community, and the best online betting sites help you stay connected with fellow bettors. You can spot good value lines early, get real-time updates on player injuries, learn from others’ strategies and mistakes, and enjoy the overall social vibe from the fun banter that goes on.

Joining sportsbook forums or Discord groups makes it even better and it’s just more fun when you can chat, share tips, and celebrate your wins with others.

Baseball betting is fun with the right tips

Baseball betting is really a lot more fun when you have the right tips. It’s all about reading the game, trusting your instincts, and enjoying the ride. Now that you know the basics like moneylines, run lines, and totals, you’re better equipped to spot good opportunities and dodge rookie mistakes. So, go on to put the tips we’ve shared here to good use and remember, the best part is to have fun while you’re at it.
