What every rookie must know

First problem: you see a line of numbers and feel lost. By the way, those numbers aren’t random; they’re the language of profit. The moment you recognize a moneyline, runline, or total, the game changes. This guide strips the jargon down to raw, usable bits, no fluff, just the core you need to start betting like a pro. Look: knowledge equals leverage.

Moneyline vs. Runline

Moneyline is simple: pick the winner, ignore the score. A two‑digit negative sign means the favorite, a plus sign signals the underdog. Example: -150 means bet $150 to win $100, while +130 flips it. Runline adds a twist—think of it as baseball’s version of point spread. The favorite must win by more than 1.5 runs; the underdog can lose by one and still win your bet. It’s a razor‑thin margin that creates big upside.

Over/Under (Totals)

Here’s the deal: totals are a prediction of combined runs for both teams. The sportsbook posts an “over/under” number, say 8.5. Bet the over, you’re saying you expect nine or more runs. Bet the under, you’re betting eight or fewer. The line moves throughout the day as injuries, weather, and lineups shift. A short sentence: watch the line. A longer one: the best bettors skim the starting pitcher’s ERA, the bullpen’s fatigue, and even the stadium’s altitude before committing.

Parlays and Props

Parlays bundle two or more selections into one ticket. Win all, reap exponential reward. Lose one, walk away empty‑handed. It’s high‑risk, high‑reward—don’t chase it at the start. Props are single‑event wagers: first‑inning run, total strikeouts, even whether a player will steal a base. These micro‑bets are gold mines for those who study player tendencies. The key: stick to markets you understand, not just the hype.

Odds formats: American, Decimal, Fractional

Most U.S. sites use American odds, the plus/minus style you’ve just seen. European fans see decimal odds—multiply your stake by the number to get total payout. Fractional odds, the British classic, display as a fraction, like 5/2. Converting is trivial: American +200 equals decimal 3.00, which is a 2/1 fraction. Master the conversion, and you’ll never be caught off‑guard by a foreign sportsbook.
