An action bet is a bet that is an option offered by some bookies on moneyline bets. If you choose the ‘Listed Pitcher’ option and the scheduled starting pitcher doesn’t play, your bet will be voided. However, if you go for an ‘Action bet’ it doesn’t matter what pitcher starts, your bet will count. As we outlined in our expert baseball betting advice, watch the odds as sharp money may come for team that changes their starting pitcher just before a game starts.
