This is a bet on the over/under for the total number of strikeouts recorded by a selected starting pitcher.
In order for bets on this market to have action, the game must complete the first 5 innings.
If the pitcher does not start the game, bets will have no action. Or, in the unlikely event the pitcher starts (takes the mound) but is removed before throwing a single pitch, bets will have no action.
If the pitcher starts and throws at least one pitch, bets will have action, even if the pitcher is then removed from the game at any point (either due to injury or coach’s decision).
