Cover the Spread: Guide to Point Spread Betting
Master point spread betting: Learn how to cover the spread and win consistent bets.
Understanding Cover the Spread in Sports Betting
Covering the spread is one of the fundamental concepts in sports betting that every bettor needs to master. Whether you’re new to sports gambling or looking to refine your betting strategy, understanding what it means to cover the spread is essential for making informed wagers and maximizing your potential returns. In simple terms, covering the spread means that a team wins or loses by a specific margin of points that has been designated by the sportsbook.
The concept might seem straightforward on the surface, but there are numerous nuances and considerations that separate casual bettors from successful ones. This comprehensive guide explores everything you need to know about covering the spread, from basic definitions to advanced betting strategies that can help you make more profitable decisions.
What Does Cover the Spread Mean?
Covering the spread is the ultimate goal of every bettor who places a point spread bet. When you cover the spread, you win your wager because the outcome of the game matches your prediction regarding the margin of victory or defeat.
For example, if Team A is listed as a -3.5 point favorite and you bet on them to cover the spread, they need to win the game by 4 or more points for your bet to win. If Team B wins the game or loses by 3 or fewer points, your bet loses. The spread essentially levels the playing field between a stronger team and a weaker team, allowing bettors to find value in wagering on both sides of a matchup.
The beauty of point spread betting lies in its flexibility. Unlike moneyline bets where you simply pick which team wins, spread betting allows you to profit whether a favorite team wins by a large margin or an underdog team keeps the game closer than expected.
The Basics of Point Spreads
Understanding the basic components of a point spread is crucial before placing any wager. Every point spread contains several key elements that work together to define how your bet wins or loses.
Favorites and Underdogs
In every matchup, one team is designated as the favorite and the other as the underdog. The favorite is the team that oddsmakers believe is more likely to win the game. This team is always listed with a negative (-) sign before the number. The underdog, conversely, is listed with a positive (+) sign before the number.
A team listed as a -7 point favorite must win by 8 or more points to cover the spread. A team listed as a +7 point underdog can either win the game outright or lose by 6 or fewer points to cover. The larger the spread, the greater the perceived gap in quality between the two teams.
How to Read Point Spreads
Reading a point spread correctly is fundamental to successful betting. When you see a line like “Team A -5.5 vs. Team B +5.5,” the negative sign indicates the favorite must win by more than 5.5 points, while the positive sign indicates the underdog can lose by 5.5 points or fewer and still cover.
The .5 (half-point) is included specifically to prevent ties or “pushes” in most cases. In college football, for instance, if Clemson is a 5.5-point favorite over LSU and you bet on Clemson to cover, they need to win by 6 or more points for your bet to win. If you bet on LSU, you need them to win the game or lose by 5 or fewer points to win your bet.
Understanding Betting Odds on Spreads
Beyond the point spread itself, bettors must also understand the odds attached to the spread. The standard odds on most point spreads are -110 on both sides, though these can vary depending on the sportsbook and the specific matchup.
When odds are set at -110, this means you need to wager $110 to win $100. If you bet $100 on a spread at -110 odds, you would win $90.90 in profit. These odds are designed to pay for the sportsbook’s commission, known as the “vig” or “vigorish.”
In some cases, especially with alternative point spreads, the odds may differ significantly from -110. A team might be offered at +150 or -200 odds, which changes the potential payout. Understanding how to calculate your potential winnings based on different odds is essential for comparing value across different betting opportunities.
Spread Betting Across Different Sports
Point spread betting isn’t limited to football. Most major sports utilize some form of spread betting, though the specific structure and terminology may vary.
Football and Basketball
Football and basketball are among the most popular sports for spread betting. The methodology is identical: the favorite must win by more than the spread, while the underdog can lose by less than the spread or win outright. Spreads in these sports are typically whole numbers or half-numbers to ensure clarity.
Hockey and the Puck Line
In hockey, the spread is typically 1.5 goals and is referred to as the “puck line.” If Team A is a -1.5 favorite with odds set at +150, you need Team A to win by two or more goals to cover the spread. If they do and you wager $10, you win $15 because of the +150 odds. If you wager on Team B at +1.5 with -200 odds and they either win the game outright or lose by one goal, you win $5 on a $10 bet based on the -200 odds.
Baseball and the Run Line
Baseball betting uses the “run line,” which functions similarly to the puck line in hockey. The run line can be wider than 1.5 in many cases. If Team A is set as -2.5 run favorites at +200 odds and you wager on them, you need that team to win by three or more runs to win your bet. If you bet on Team B at +2.5 with -300 odds, you need them to win or lose by two runs or fewer to win the bet.
The Concept of a Push
One important scenario that can occur when betting spreads is a “push.” A push happens when the game ends with a result that exactly matches the point spread, resulting in neither a win nor a loss for your bet.
In an NFL example, if you bet the Packers to cover the +3 spread and the final score is Vikings 28, Packers 25, the bet pushes and you get your wager back. However, if the Packers win or lose by 2 or fewer points, you win your bet. This is why sportsbooks typically use half-point spreads (.5) to eliminate the possibility of pushes.
How to Bet Against the Spread
Betting against the spread isn’t simply about picking which team wins a game. It’s about analyzing which team you believe will win or lose by a specific amount, and making a calculated wager based on that analysis.
Analyzing Spreads
When evaluating whether to bet on a favorite or underdog spread, you must consider several factors:
In closer spreads, like a 3-point matchup, you need to ask yourself if the underdog is capable of keeping the game within 3 points. In bigger spreads, where one team is perhaps a 10.5-point underdog, your analysis should focus on why you believe that team will keep the game closer than oddsmakers predict.
It’s also important to note that spreads change in the lead-up to a game based on injury news, weather forecasts (where applicable), and other extenuating factors. Monitoring line movements can provide valuable insight into where smart money is being wagered.
Why Bettors Choose Spread Betting
Many bettors prefer spread betting for several compelling reasons. First, spread betting often offers better returns on investment compared to moneyline betting, especially when wagering on favorites.
When betting the Vikings to win outright as a three-point favorite using moneyline odds, the odds might be set at -150, meaning you’d have to bet $150 to win $100. In contrast, a $100 bet on the Vikings to cover the spread at -110 odds would net a return of $90.90. That same $100 bet on the Vikings using moneyline odds would only net a return of $66.70, demonstrating the value advantage of spread betting.
Additionally, spread betting appeals to bettors who like underdogs to keep games close without necessarily winning outright. This flexibility creates more betting opportunities and allows for a more nuanced approach to sports wagering.
Examples of Covering the Spread
Let’s examine specific examples across different sports to solidify your understanding.
College Football Example
Clemson is a 5.5-point favorite over LSU. If you bet on Clemson to cover the spread, they need to win by 6 or more points for your bet to win. If the final score is Clemson 28, LSU 20, you win your bet. If the final score is Clemson 26, LSU 21, you lose because they only won by 5 points, which is less than the 5.5-point spread.
NFL Example
The Vikings are a 3-point favorite over the Packers. If you bet on the Vikings to cover, they need to win by 4 or more points. If you bet on the Packers to cover at +3, they either need to win the game or lose by 3 or fewer points. If the final score is Vikings 24, Packers 21, the Packers cover their spread, and bettors who wagered on them win their bets.
Frequently Asked Questions
What is the difference between covering the spread and winning a moneyline bet?
Covering the spread means winning by a specific margin or losing by less than the spread. A moneyline bet is simply picking which team wins the game outright. Spread betting typically offers better odds on favorites and allows you to profit from underdog teams that keep games close.
How do sportsbooks determine point spreads?
Sportsbooks use sophisticated statistical models, injury reports, weather data, historical performance, and other factors to set initial spreads. The spreads are then adjusted based on how much money is wagered on each side to balance action and manage their risk exposure.
What does it mean when a spread is -3.5?
A -3.5 spread means that team is favored by 3.5 points. They must win by 4 or more points to cover. If you bet on the other team at +3.5, they can lose by 3 or fewer points or win the game to cover.
Can spreads change after I place my bet?
Yes, spreads change constantly based on betting action, injury updates, and other information. However, once you place your bet at a particular spread and odds, those numbers are locked in for your wager, regardless of subsequent line movements.
What is a “key number” in sports betting?
Key numbers are common point differences in sporting outcomes. In football, 3 and 7 are crucial because they’re common scoring margins (field goal and touchdown). Getting the best side of these numbers can significantly impact your long-term profitability.
Strategic Considerations for Spread Betting
Successful spread betting requires more than just understanding the mechanics. You need to develop a strategic approach to identifying value and making consistent profitable decisions over time.
One important consideration is recognizing when spreads offer value relative to your own analysis. If you believe a team will win by 5 points but the spread is only -2.5, that favorite offers value. Conversely, if you think an underdog will cover a +7 spread but you’re uncertain about them keeping the game that close, that may not represent good value.
Another critical factor is managing your bankroll effectively. Consistent profitability in spread betting comes from making disciplined, calculated wagers rather than chasing losses with increasingly large bets. Professional bettors typically wager only 1-5% of their total bankroll on any single game.
