How to Bet on MLB Baseball: Moneylines, Run Lines & Totals

Updated February 2026 • 8 min read

Baseball betting is different. With 162 games per team and a six-month marathon from April through September, MLB offers the most betting opportunities of any major sport. But baseball's unique rhythms — starting pitchers, bullpens, weather, and high variance — require a different approach than football or basketball.

MLB Betting Basics

Baseball is a moneyline sport. Unlike football and basketball where point spreads dominate, MLB betting centers on picking winners at varying odds. The favorite might be -200 (risk $200 to win $100) while the underdog is +170 (risk $100 to win $170).

Key Insight: Even the best teams lose 60+ games per year, while the worst teams win 60+. Baseball has more parity than any major sport — underdogs win roughly 40% of the time.

This high variance is both opportunity and danger. You can find value every day, but you need proper bankroll management to survive the inevitable cold streaks.

Main Bet Types

Moneyline

The most popular MLB bet. Simply pick the winner.

Example: Yankees -140, Red Sox +120

Run Line

Baseball's version of a point spread, almost always set at 1.5 runs. The favorite gives 1.5 runs, the underdog gets 1.5.

Example: Dodgers -1.5 (+140), Padres +1.5 (-160)

Run Line Strategy: Take favorites on the run line when they're heavily favored (-180 or more on moneyline). Take underdogs on the run line when the game should be close.

Total Runs (Over/Under)

Combined runs scored by both teams. MLB totals typically range from 6.5 to 11.5 runs.

Example: Rockies vs Giants Total 9.5

Pitching: The Foundation

Starting pitching drives MLB betting more than any other factor. A ace versus a struggling starter can shift odds by 50+ cents.

Key Pitcher Stats

Pitcher Type Betting Angle What to Watch
Aces (Sub-3.00 ERA) Often overpriced, look for value against Recent performance, matchup history
Struggling starters Fade early in season, value later Underlying metrics improving?
Rookies/debuts High variance plays Minor league numbers, scouting reports
Bullpen games Usually higher totals Bullpen depth and recent usage

Bullpen Considerations

Starting pitchers rarely complete games. Bullpen quality is crucial:

Weather & Park Factors

Weather Impact

No sport is more affected by weather than baseball:

Weather Resources: Check weather conditions at ballpark level. Sites like WeatherUnderground or AccuWeather provide wind direction and speed crucial for totals betting.

Ballpark Effects

Every ballpark plays differently:

Stadium Type Examples Betting Effect
Hitter-friendly Coors Field, Great American Ball Park Higher totals, favor overs
Pitcher-friendly Petco Park, Marlins Park Lower totals, favor unders
Neutral Most stadiums Focus on pitching and hitting matchups

Player Props & Specials

Popular Player Props

Team Props

Prop Strategy: Focus on players with consistent playing time and favorable matchups. Avoid betting props on players facing elite pitching unless the price is right.

Winning Strategies

Focus on Starting Pitching

Great pitchers don't guarantee wins, but they give their teams the best chance. Look for:

Target Totals Over Sides

MLB totals often provide better value than moneylines because:

Line Shopping is Crucial

With so many games daily, odds vary significantly between books. Getting -120 instead of -140 on the same bet dramatically improves long-term profits.

Bet Series, Not Games

Consider betting team series (which team wins 2 of 3 games) rather than individual games. This smooths out some of baseball's inherent variance.

Series Strategy: Strong teams often bounce back after bad losses within the same series. Look for value on favorites after they lose game one.

Track Umpires

Home plate umpires affect games more than most realize:

Season Breakdown

Period Months Betting Characteristics
Opening Month March-April Weather unpredictable, small samples, public overreactions
Early Season May-June Teams establish identity, weather improves, better data
Mid Season July-August Trade deadline effects, dog days fatigue
September September Playoff races, call-ups affect team composition
Playoffs October Elite teams only, tighter lines, more public action

Key Season Events

Common Mistakes to Avoid

Overvaluing Big Names

Star players command higher prices, but baseball is a team sport. A great hitter can't overcome terrible pitching.

Ignoring Weather

15+ mph winds can turn routine fly balls into home runs or easy outs. Always check weather before betting totals.

Weather Rule: Strong winds blowing out = bet the over. Strong winds blowing in = bet the under. It's that simple in many cases.

Betting Too Many Games

With 15 games daily, it's tempting to have action on everything. Focus on games where you have clear edges.

Overreacting to Small Samples

A pitcher's first two starts don't define their season. Look for larger sample sizes before making judgments.

Ignoring Bullpen Usage

If a team used their best relievers heavily in recent games, they may struggle in close situations.

Advanced Analytics

Modern baseball betting increasingly relies on advanced metrics:

Sites like FanGraphs and Baseball Reference provide these metrics free. They often reveal which teams are due for regression.

Where to Bet MLB Games

All major sportsbooks offer extensive MLB markets. DraftKings and FanDuel typically have the most player props, while books like BetRivers and PointsBet often have competitive run line prices. Always compare odds across multiple books.

Bankroll Management: Baseball's high variance requires conservative bet sizing. Even sharp bettors experience long cold streaks. Never bet more than 2-3% of your bankroll on a single game.

Final Thoughts

MLB betting rewards patience and discipline over volume. With 2,430 regular season games, you don't need to bet them all to find value. Focus on developing expertise in specific areas — whether that's totals, specific divisions, or pitcher props — and wait for your spots.

Baseball's long season creates fatigue and complacency in the betting market. Sharp bettors who stay focused through the dog days of summer often find their biggest edges in August and September when others have moved on to football.
