MLB Spring Training typically runs from mid-February through late March, with pitchers and catchers reporting around February 12-15 and full-squad workouts beginning a few days later. Exhibition games — split between the Grapefruit League in Florida and the Cactus League in Arizona — kick off in late February and run through approximately March 25, just before Opening Day in late March or early April. While Spring Training betting markets are available at most major sportsbooks during this window, futures markets tied to the upcoming regular season begin appearing as early as the prior October, immediately after the World Series concludes. These early futures — World Series winner, pennant winners, division champions, and season win totals — represent some of the most valuable lines bettors will encounter all year, as books are still calibrating to off-season roster movement.

The MLB off-season offers a rich landscape of betting opportunities beyond simple futures. Player prop markets such as AL/NL MVP, Cy Young, Rookie of the Year, and home run leader are typically posted by November and shift meaningfully through free agency and trade season, which peaks from December through February. Win totals — over/under lines set for each team's regular-season victories — are among the most popular off-season bets, and they react sharply to marquee signings. When a team like the Dodgers adds a frontline starter or a club like the Cubs lands a premier free-agent bat, win totals can move two to three games almost overnight. The MLB Draft in July has a more muted betting impact compared to the NFL or NBA, but international signing periods and Rule 5 Draft results in December can subtly reshape organizational depth and long-term futures pricing.

Vig patterns in baseball betting follow a distinct seasonal arc. Preseason and early-season moneylines tend to carry wider margins — often 25 to 35 cents of juice on Spring Training exhibition games — because books face lower handle volumes and greater uncertainty around lineup configurations, pitcher usage, and roster cuts. As the regular season matures and sharps establish reliable models around pitching rotations and bullpen usage, margins on daily moneylines tighten to roughly 15-20 cents at competitive books. The sharpest value windows historically fall in two places: early futures posted right after the World Series, before the market fully prices in free-agency outcomes, and the first two weeks of the regular season, when books are still adjusting to actual performance data versus spring projections. Major odds movements during the off-season are driven primarily by free-agent signings, blockbuster trades, and significant injury news — a torn UCL requiring Tommy John surgery for a team's ace, for example, can crater World Series odds and push win totals down by four or more games within hours.

How We Calculate These Numbers

Data Source: All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
Update Frequency: We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
Vig Calculation: Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
Per-Market Breakdown: We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
Grading Scale: Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
Trend Tracking: We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
