MLB Betting Stats 2025 2025

What are MLB betting stats? 📝

MLB betting stats offer deep insights into how teams perform not just on the diamond — but in relation to oddsmakers’ expectations. With a 162-game season and daily betting opportunities, knowing how to use metrics like ATS, O/U, and situational splits can be the difference between blind betting and sharp strategy.

Here’s a breakdown of the key stats on this page and how to use them for more profitable baseball betting.

ATS (Against the Spread / Runline)

What it means: In MLB, ATS typically refers to runline betting — where a team must win by 2+ runs (–1.5) or lose/win by fewer than 2 runs (+1.5).

How to use it: A team like the Rays could be 60-45 ATS, indicating they’ve consistently beaten the runline. Underdogs that win outright or keep games close often offer ATS value.

📌 Runline stats are essential when deciding whether to bet a favorite straight up or lay the –1.5.

O/U (Over/Under Totals)

What it means: Tracks how often games go Over or Under the posted total runs.

How to use it: Team tendencies — like high-powered lineups or unreliable bullpens — directly influence totals. If the Rockies are 68-40 to the Over, it often signals offensive firepower or Coors Field factor.

📌 Factor in ballpark effects, pitching matchups, and weather when betting totals.

SU (Straight-Up)

What it means: Outright win-loss records.

How to use it: Great for evaluating moneyline betting opportunities. Teams might be profitable SU without being elite — especially with plus-money value. For example, the Orioles may be 55-50 SU but +10 units due to frequent underdog wins.

📌 Use SU stats alongside profit/loss metrics to gauge value beyond win totals.

Home/Away Splits

What it means: Tracks performance based on location.

How to use it: Some teams dominate at home but collapse on the road. If the Padres are 35-20 ATS at home but 20-40 away, location should strongly influence your wager.

📌 Ballpark familiarity, travel, and lineup depth often shift performance drastically between venues.

Division/League Records

What it means: Shows how teams fare against divisional or league opponents.

How to use it: Divisional matchups are common and often tight. A team with a strong ATS record vs. its division may be particularly effective at exploiting familiar opponents.

📌 Use this when betting series between rivals or when playoff races heat up late in the season.
