Many sports bettors assume betting favorites is a reliable strategy because stronger teams win more often.

But while favorites do win frequently in MLB, the key question is whether those wins translate into profitable betting results. mlb betting favorites analysis shows that understanding the performance of these top teams can help bettors make more informed decisions. By examining historical trends and current matchups, it’s possible to identify when a favorite might be overvalued or undervalued. Recognizing patterns in player performance and injury reports can further enhance the likelihood of achieving profitable outcomes.

To examine this, we analyzed every MLB game since 2004.

Favorite Betting Results Since 2004

SU: 30,008 – 21,514
Win Rate: 58.2%
ROI: -1.8%
Profit/Loss: -$141,209

Favorites have won 58.2% of MLB games over this period.

However, betting every favorite still produces negative long-term returns because sportsbooks adjust prices to account for the higher probability of winning.

Even though favorites win far more often, sportsbooks price them aggressively enough to eliminate long-term profitability.

    1. That’s the assumption most people make. The issue is the price you’re laying — you’re often paying more than that win rate justifies.
