How To Bet
In baseball, a money line takes the place of a point-spread. When it comes to money line betting, you need just need the team you select to win the game straight up, regardless of the margin. In money line wagering, you always have a favorite and an underdog. The minus sign (Ex. Nationals -120) indicates the favorite and the amount you must wager to win $100. In the above example, bettors would stake $120 to win $100 on the Nationals. The plus sign (Ex. Phillies +100) indicates the underdog and the amount you will win for every $100 wager. In this case, bettors would place $100 on the Phillies to win $100.
The "O/U", also known as Over/Under or Total, is the number of combined runs that the oddsmakers expect to be scored in the matchup. Bettors can either wager Over or Under on the runs listed. In the above example, 10 runs, bettors taking the Over would win if the Phillies and Nationals score 11 or more runs in the game. Bettors taking the Under would win if the two teams combine for nine runs or less. If the game ends with 10 runs, it is considered a push (tie) and all wagers are refunded. Oddsmakers often associate a money line with "O/U" lines, which means bettors would have to lay extra money in some cases. Ex. Over 10 (-120) -- Bettors would wager $120 to win $100.
The Run Line is a combination of a money line and point-spread wager. In most cases, the Run Line is always plus or minus 1 ½ runs. Put simply, you either wager on a team to win by two or more runs or you bet on a team to either win outright or lose by just a single run. Since bettors are at a disadvantage by taking the favorite, oddsmakers install a positive return. In the above example, the Nationals are - 1 ½ (+160) and the Phillies are +1 ½ (-180). If you $100 on the Nationals, you would earn $160 if they won the game by two or more runs. If they lost the game outright or won by exactly one run, you would lose your $100 wager. If you bet $100 on the Phillies, you would have to put up $180. This wager will win if Philadelphia wins outright or if they lose by exactly one run.
All betting shops and bookmakers follow their own house guidelines, but the rules listed below are widely considered industry standards
Bettors have two options when making money-line bets in baseball -- Action and Listed Pitchers.
-- Action Bet - This is a wager where you pick a team regardless of the starting pitcher on the team. If a scheduled pitcher on either team is scratched after you make your wager, your bet is still active.
-- Listed Pitchers Bet - This is a wager where you bet on a game based on the starting pitchers for both teams. If a scheduled pitcher on either team is scratched after you make your wager, your bet is deemed "no action" and refunded.
-- Winners and Losers are official after 5 innings of play unless the home team is leading after 4 ½ innings. If a game is called or suspended, the score after the last full inning determines the winner. If the home team scores to tie - or takes the lead in the bottom half of the inning— the score at the time the game is called determines the winner. Wagers will be refunded if the home team ties the game and it is then suspended. Games that are suspended will not carry over to the following day.
-- When wagering on the Totals (O/U), the game must go 9 full innings or 8 ½ innings if the home team is ahead to have action.
-- When wagering on the Run Line, the game must go 9 full innings or 8 ½ innings if the home team is ahead to have action.
