Baseball betting works differently from football and basketball. There's no point spread — the primary market is moneylines. The starting pitcher is the single biggest variable. And with 162 games per team, managing your bankroll across a long season is essential.
The Main MLB Bet Types
Moneyline: Pick who wins the game. The only option for many bets. Favorites are negative odds, underdogs are positive.
Run line: The baseball spread — always set at ±1.5 runs. Betting a team -1.5 means they must win by 2+. Betting +1.5 means they can lose by 1 run and you still win. Favorites on the run line get better odds than the moneyline.
Total (over/under): Bet whether combined runs will exceed or fall short of the line. Typically set between 7.5 and 9.5 for most MLB games.
First-5-innings bets: Half-game bets covering just the first 5 innings — useful when you have a strong opinion on the starting pitcher but not the bullpen.
The Pitcher Variables
Always know before betting:
- Who is the confirmed starting pitcher for each team?
- What's their recent ERA and FIP over the last 5 starts?
- How many days of rest do they have?
- How does this pitcher perform against left-handed vs. right-handed lineups?
A starting pitcher change can move a line by 50+ cents. If you bet before a scratch is announced, you may be stuck with a bet that no longer reflects the game you analyzed.
Bankroll Across 162 Games
Baseball's long season requires bankroll discipline. Never risk more than 1-2% per game. A bad 50-game stretch can happen to any bettor — you need to survive it without going broke.
