Baseball Betting Rules


  • When wagering on total runs (over/under) the game must go 9 innings (8.5 if the home team is ahead) to have action. If a game is called or suspended in extra innings, the score will be determined after the last full inning unless the home team scores to tie, or takes the lead in the bottom half of the inning, in which case the score is determined at the time the game is called.

  • Wagers on total runs will be refunded if a pitcher change occurs prior to both listed pitchers throwing at least one pitch.

  • Rules for Run Line wagers are the same as those for baseball totals.

  • The result of a game is official after 5 innings of play unless the home team is leading after 4.5 innings. If a game is called or suspended, the winner is determined by the score after the last full inning unless the home team scores to tie, or takes the lead in the bottom half of the inning, in which case the winner is determined by the score at the time the game is called. Monies will be refunded if the home team ties the game and it is then suspended. Events will not carry over to the following day unless otherwise specified.

  • Instant Action Sports does not recognize postponed games, protests or overturned decisions for wagering purposes. All baseball wagers must go the day written, otherwise there is no action and all monies are refunded.

  • Money-line wagers on baseball will be accepted in the following manner:
    • Action - team against team, regardless of the starting pitchers.
    • Listed Pitchers - if both starting pitchers are not exactly as specified at the time of the bet, the wager will be deemed "no action".
    • One Listed Pitcher - this is a wager on or against one specified pitcher, regardless of the other starting pitcher. If the specified pitcher does not start, the wager is deemed "no action". (examples: "the Yankees versus Martinez" indicates a wager against Martinez. "Martinez against the Yankees" indicates a wager on Martinez).

  • In the event there is a pitching change prior to the game, the money-line will be re-adjusted and "action" wagers will be graded using the opening price for the new pitcher.

  • A pitcher is deemed a starter after throwing the first pitch to the opponent's first batter.

  • Wagers on totals and run-lines must always specify both pitchers listed.

  • Double Headers: Double header games are denoted as Game1 or Game2. Members may list pitchers in a double header, however, wagers are taken on games, not pitchers. If a scheduled pitcher does not go in his scheduled game of a double header but in the other game, wagers are graded based on the Game, not on the pitcher.

  • A baseball team must play at least 160 games for wagers on its season wins to have action.

  • We use the 10-cent line on sides only!
  • The Baseball Grand Salami has no action if any game is rained out or final in less than 8� innings.

First-Half Betting (First five innings of the game):

  1. All wagers on baseball first halfs (5 innings) will be decided on the basis of the score at the end of first five full innings.

  2. Once 5 full innings have been completed, all wagers on the first half are oficial.

  3. If a game does not go five full innings, all first-half wagers will be canceled.

  4. All first-half wagers (5 innings) must list both pitchers. If either listed pitcher does not start, wagers on the first half (5 innings) will be deemed no action.

  5. No hookups with the first-half lines and its respective parent game are accepted, for example:

    2 Team Parlay
    N.Y. Yankees 1H -165
    N.Y. Yankees -1½+115    not accepted

    2 Team Parlay
    N.Y. Yankees 1H -165
    N.Y. Yankees o5½+115   good

Regular Season Baseball Series Wagers:

  1. Wagers on baseball series are based on the first three games played of each series (on a 4 game series only first three games count for any wager on MLB Series).
  2. Neither team can play another opponent between scheduled games.
  3. At least two of the first three series games must be played for wagers to have action.
  4. Once a team wins two games in a series, the series will be graded at that time.
  5. If only one of the first three games is postponed or canceled, series wagers stand as written (In case of a 1 - 1 push situation, all wagers should be graded as tie).
  6. If two of the first three games are postponed or canceled, all wagers on that series will be graded as No Action and the money will be refunded.
  7. A called game will count toward a series wager provided it is officially declared a regulation game.
  8. Pitchers cannot be listed for series wagers; all wagers will have action regardless of the starting pitchers.

Money Line Wagering

Wagering on baseball is done by risking more money than the win amount
on favorites (Mets) or risking less to win more on dogs or underdogs
(teams not favored to win).

Example:

Mets -135
Reds +115

  • If you wager on the Mets -135 you lay $135 to win $100.
  • If you wager on the Reds +115 you lay $100 to win $115.

Totals Over/Under

There is a standard 20 cent line.

Example:

Mets 7 over -120
7 under Even Money

  • If you take the Mets over 7 runs you lay $120 to win $100.
  • If you take the Reds under 7 you lay $100 to win $100 (even money).
  • The team doesnt matter. You are only wagering on the total runs of the game.

Run Line Wagering

A baseball Run Line wager is a combination of the point spread and the money line. The team wagered on must win by the point spread while the amount wagered is determined by the money line odds.  

Example:

Braves -1 1/2 +130
Pirates +1 1/2 -150

  • If you wager on the Braves you must win by 2 or more runs. You would lay $100 to win $130.
  • If you wager on the Pirates they cannot lose by 2 or more runs. You would lay $150 to win $100.

Parlays

How to calculate a money line baseball parlay:

  • Possitive money line divide 100 plus one.
  • Negative money lines divide 100 by the negative money line plus one.
  • Multiply the results among themselves times the amount minus the amount.

Example:

3 team parlay for $30
Cubs +115
Mets -125
Phillys +130

115÷100 = 1.15+1 = 2.15
100÷125 = 0.8 +1 = 1.8
130 ÷100 = 1.3+1 =  2.3
2.15 * 1.8 * 2.3 = 8.901
8.901 * $30 = 267.03
267.03 - $30 = $237.03
Payout will be $237
