If you bet under you lose. There are parlays and teasers and exotics. As we have said, these are not good bets. It is okay to bet on a series, however, taking one side or the other. One thing professional basketball provides are play-off series. You gamble not on one game, but who will win a best of 5 or best of 7 game play-off series. It is usually expressed in Baseball is one team sport where one person (the pitcher) largely influences the betting line.
An ace pitcher who is hot will usually trump a good team as far as the oddsmakers are concerned. Previous games circumstances, winning and losing streaks, even umpires will influence. There are plenty of games from April through late October and the College World Series gets some action. The listed starting pitchers must start for each team for the bet to be honored.
If for some reason one of the pitchers is scratched, then the bet is considered no action and all money is returned. Most baseball bets are expressed as odds or moneyline bets. Sometimes you will see an over/ under for total runs scored between both teams. If the final score is Phillies 8, Braves 7, then the total would be 15.
