Introduction

Betting on underdogs is one of the most rewarding strategies in sports betting, yet it’s often misunderstood or overlooked. While betting on the favorite might seem safer, underdogs can offer great value if you know when and how to spot them. This guide will walk you through effective strategies to successfully bet on underdogs in 2025 and maximize your returns.

Why Underdogs Hold Value in Sports Betting

The general public tends to favor favorites, inflating their perceived value. Sportsbooks, knowing this, often set lines that underestimate the potential of underdogs, especially in sports with high volatility such as MLB, UFC, and college football. Recognizing this imbalance is key to spotting underdog value.

Strategy 1: Look for Close Odds

Underdogs with odds in the +120 to +160 range are worth paying attention to. The implied probability of these underdogs is often closer to 50/50, making them valuable if your research suggests they have a reasonable chance of winning. These odds indicate that sportsbooks are uncertain, and it’s the perfect opportunity to capitalize on this lack of clarity.

Strategy 2: Track Line Movements

Sharp bettors often bet early on underdogs, which is why line movements can provide insight. When you see an underdog’s odds shift dramatically, especially after opening, it’s a signal that significant money is coming in on them. If you can spot this before the market fully adjusts, you’re in a great position to take advantage of favorable odds.

Strategy 3: Capitalize on Live Betting

Live betting can be an excellent way to profit from underdogs, especially those that start slow but have the potential to rally. For instance, in sports like the UFC or MLB, underdogs with great conditioning or deep bullpens often turn the tide in the later stages of the game. Live betting allows you to place a wager when the momentum shifts in favor of the underdog, offering higher value.

Strategy 4: Use Correlated Parlays to Increase Value

If you’re confident in an underdog, combining that bet with an under or other correlated outcomes can increase the potential payout. For example, if you believe in a football underdog’s chances of winning, pairing that with an under bet can increase your potential returns. Just ensure the sportsbook allows this type of parlay, and be mindful of the increased risk.

Strategy 5: Focus on Underdogs with Strong Defense

Defense can often make or break an underdog’s performance, especially in sports like football and basketball. Teams with solid defenses can limit high-scoring offenses and keep games closer, even when they are outmatched on paper. Betting on underdogs with good defensive units or a slow tempo can help mitigate the variance of unpredictable match outcomes.

Strategy 6: Remove Emotion from Your Bets

Betting on an underdog can evoke strong emotions, particularly if you’re backing a team you personally dislike or have strong feelings about. However, successful sports betting requires a clear, analytical approach. Avoid betting based on emotion or loyalty to a team. If the odds are right and the data backs it up, place the bet regardless of your personal preferences.

Strategy 7: Avoid Large Underdogs Without a Solid Reason

Underdogs with odds above +250 are a much riskier proposition. Betting on these teams can be highly speculative, and without a clear reason (like an injury to a key player on the favorite, or poor weather conditions), these bets are often a gamble. While it can be tempting to back long shots, it’s important to have a specific angle to justify the risk.

Final Thoughts

Betting on underdogs is not about blind hope—it’s about finding value. While these bets may carry more risk, they also come with greater reward if you focus on data-driven strategies and value opportunities. By using the strategies outlined in this guide, you’ll be well-equipped to bet on underdogs intelligently and consistently, increasing your chances of success in 2025.
