How to Bet ALCS Game 5 – Popular MLB Betting Markets

Moneyline – The simplest way to bet baseball. You’re picking which team wins the game outright. For Game 5, if you take the Mariners moneyline and they win, your bet cashes - regardless of the final score. The Blue Jays are slight favorites heading into tonight’s matchup.

Run Line (Spread) – Baseball’s version of the point spread. Usually set at –1.5 / +1.5 runs. If you bet Blue Jays –1.5, they must win by two or more runs for your ticket to cash. If you take Mariners +1.5, they can win outright or lose by just one run and still cover.

Over/Under (Total Runs) – Here you’re wagering on how many total runs both teams will score combined. For example, if the line is Over/Under 7, betting the Over means you need at least eight combined runs; betting the Under means you need six or fewer.

Player Props – Bet on individual player performances. Popular markets include Total Hits, Home Runs, Strikeouts, or RBIs. For instance, you might back Julio Rodríguez to record 2+ hits or Vladimir Guerrero Jr. to hit a home run.

Inning / Team Totals – Wager on how many runs a team will score in a specific inning or over the entire game. For example, you can bet Seattle Over 0.5 runs in the 1st inning or Toronto Under 3.5 total runs.

Same Game Parlays (SGPs) – Combine multiple bets from the same game into one slip for higher potential payouts. Example: Blue Jays ML + Vladimir Guerrero Jr. HR + Over 7.5 runs. The odds multiply, but so does the risk - all legs must hit for the bet to cash.
