Introduction
The page will endeavor to give the recreational baseball bettor advice on the various bets. I have no handicapping skill in baseball whatsoever, so the best I can do is steer you towards the best type of bets. There are three primary ways to bet on baseball, as follows.
- Money line: Bet on which team will win.
- Total: Bet on whether the total number of runs will fall above or below a stated number, usually between 7 and 12.
- Run line: Similar to a bet against the spread in football or basketball. However, in baseball the better team is always favored by 1.5. If the money line indicates neither team is favored, then either team could be the favored team.
Source of Data
The data this analysis is based on is from the Major League Baseball games played over the 2016 and 2017 seasons. I had to remove two games because of incomplete data. The total number of games this page is based on is 4,929.
Fun Facts
The following table shows the average number of runs, hits, errors.
MLB Averages 2016-2017
| Item | Away | Home | Total1 |
|---|---|---|---|
| Runs | 4.47 | 4.64 | 9.10 |
| Hits | 8.71 | 8.64 | 17.34 |
| Errors | 0.58 | 0.58 | 1.16 |
| Total | 13.76 | 13.87 | 27.61 |
Notes
1. Totals may not appear to agree with sum of the parts, due to rounding.
Money Line Bets
When it comes to betting money lines in baseball, or any sports bet for that matter, what is number of basis points, or 'cents' between the lines of the two teams. For example, a 10-cent set of lines would be +120/-130 or +105/+105. Following is the theoretical house edge by number of cents in the lines, assuming the probability of each team winning is close to 50%.
- 10 cents: 2.38%
- 15 cents: 3.49%
- 20 cents: 4.55%
As of this writing (Sept. 20, 2018) here are which sports book groups offer which sets of money line bets in baseball.
- 10-cent lines: Westgate, William Hill, South Point, Stations, CG Technology, Golden Nugget, Jerry's Nugget, Boyd
- 15-cent lines: Stratosphere, Caesars, Wynn
- 20-cent lines: MGM/Mirage, Treasure Island
Home or Road Teams
I show money line bets on road teams perform slightly better than home teams. To be specific, I show the house edge to be 0.3% less on road teams than home teams. This is well within the margin of error, so I wouldn't put much stock in this difference.
Favorite or Underdog
Historical Nhl Odds
Not surprisingly, I show money line bets on underdogs perform better than favorites. This seems to be true in every sport. To be specific, I show the house edge to be 0.70% less on underdogs compared to favorites.
Total Bets
The following table shows the number of times the total runs was over, under, and exactly on the over/under line. The return column shows the house edge, assuming a 20-cent line. Note that the house edge is 2.25% less on Under bets.
Over/Under Bets in MLB
| Outcome | Number | Probability | House Edge |
|---|---|---|---|
| Over | 2315 | 46.97% | 5.45% |
| Under | 2373 | 48.14% | 3.20% |
| Push | 241 | 4.89% | |
| Total | 4929 | 100.00% |
Run Line Bets
Based on sets of 20-cent lines, I show the expected return laying 1.5 runs on the favorite is 96.90% and buying them on the underdog is 96.34%. This difference of 0.56%, favoring laying the 1.5 runs, is within the margin of error.
