Houston Astros Odds

The Houston Astros had an astonishing season in 2022. They finished with a record of 117-58, winning the 2022 World Series. With a league-best 2.80 ERA in the regular season and a league-best 0.83 ERA in the postseason, the Astros' bullpen soared to the top of baseball in 2022.

Astros Spread (Run Line)

When betting on baseball, you’ll be faced with three standard options: the moneyline, over/under, and run line.

The run line is a bet on the margin of victory, like a point spread. But because baseball is low scoring, the spread will almost always be -1.5 for the favorite and +1.5 for the underdog. The payouts for each will just be adjusted based on each team’s strength.

Here’s a brief example of a run line for a hypothetical Astros game:

• Seattle Mariners (+1.5)
• Houston Astros (-1.5)

The Astros are favored by 1.5 runs against the Mariners; the minus sign (-) indicates Houston is the favorite, while a plus sign (+) is used to denote the underdog. Bettors who wanted to back Houston here would be “laying” those 1.5 runs, meaning for their bets to cash, the Astros would need to win by two runs or more. Bettors who selected the Mariners +1.5 would win if Seattle won outright or kept a loss to 1 run.

The Astros were 93-82 on run lines in 2022, covering 53.1 percent of the time – putting them as the 4th best in the league.

Astros Moneylines

Many first-time bettors are wary of run line bets, especially when riding with the hometown team. In that case, moneyline wagers are often seen as the safer way to go. A moneyline bet is a bet on who wins the game -- no run line involved.

Let’s use the same example from before to understand the moneyline better:

• Seattle Mariners +150
• Houston Astros -180

Like run lines, the minus sign (-) signifies a team is favored, while the plus sign (+) means a team is an underdog. The moneyline odds, written in American odds format here, indicate how big or small a favorite that team is, written in increments of $100. For example, to win $100 on the Astros, a bettor would need to risk $180. On the flip side, a $100 bet on the Mariners would net $150 if they pulled the upset.

The Astros went 117-58 in 2022, putting them in first place in the AL West and in first place in the MLB.

Odds can differ from sportsbook to sportsbook, so always make sure you shop for the best line with The Action Network app.

Astros Over/Unders

Betting on a team to win or cover a run line isn’t the only type of wager allowed on MLB games. Almost all sportsbooks will offer a total on the game, also known as an over/under. This bet is not on the contest's winner, but on the number of runs the two teams will combine to score; sportsbooks hang a number, and bettors can wager either over or under that total.

If the number for our hypothetical Astros-Mariners matchup were 8 runs, over bettors would require 9 points or more to cash their tickets, while those who bet the under would need 7 or fewer runs. If the two teams scored precisely 8 runs between them, that bet would push, and all wagers would be refunded.

Astros totals in 2022 were the worst in the league when betting the over, hitting at an 63-102-10 clip.

Astros Props

Some bettors find more entertainment and success betting on more specific outcomes than the game's result. Prop bets cover a wide market of wagers on player stats, discrete in-game events, and any yes/no question style. Many props are bets on specific players and their performance, such as betting Jose Altuve Jr. over 1.5 hits on a given night or betting that Lance McCullers Jr. will strikeout over 9.5 batters. Some props can be shorter, such as betting on the number of runs scored in the first five innings or who will hit a home run. Offerings vary depending on the sportsbook, so use our sportsbook reviews to find the best bet for you.

Astros Futures

In Houston, expectations are extremely high, so bettors still have to shop for the best line to get good odds on Astros' futures bets. Futures are bets that focus on long-term outcomes, like the Astros to win the AL West , win the American League Pennant, win the World Series, or even individual awards like winning league MVP.

How to Bet on the Houston Astros
