Because of the number of games in the regular season, Baseball seems to have more winning and losing streaks than other sports. Here is a tip that can help win or atleast save you money.

Bet with a current streak not against it.
If a team has been losing don't bet the team to win and if they have been winning don't bet them to lose. Betting against a streak can cost you many losing bets while betting with the streak can only cost you one.
