- Start with the moneyline. Baseball is priced mostly on the moneyline because games are low-scoring and close. A -150 favorite risks 150 to win 100; a +130 dog wins 130 on 100.
- Understand the run line. The run line is almost always 1.5 runs. A favorite at -1.5 must win by two or more; a dog at +1.5 covers by winning or losing by one.
- Weigh the pitching. The starting pitcher and the bullpen shape the total and the price. Confirm the confirmed starters before you bet.
- Shop and factor the park. Hitter-friendly parks and wind push totals up. Compare the price and the total across books.
- Bet a unit. Baseball is a grind of small edges over a 162-game season, so flat, disciplined sizing is essential.
A worked MLB example
The Dodgers are -140 on the moneyline, -1.5 (+120) on the run line, and the total is 8.5. Betting -140 risks 140 to win 100 if they simply win. Taking -1.5 at +120 pays more but they must win by two or more. If you like a pitching duel, the under 8.5 needs both teams to combine for 8 runs or fewer. Line shopping a dime of moneyline juice adds up across a long season.
Common MLB betting mistakes
- Chasing big favorites. Laying -200 on a baseball team is a fast way to bleed a bankroll.
- Ignoring the bullpen. A tired pen turns a good total read into a loss late.
- Betting before lineups post. A rested star or a scratched starter changes everything.

What is the run line in baseball?
A fixed 1.5-run spread. The favorite at -1.5 must win by two or more runs; the underdog at +1.5 covers if they win or lose by exactly one.

The moneyline is simpler and fits baseball's low-scoring, close nature. The run line adds payout but more risk on the favorite.
