1. Avoid the Early SeasonA successful professional sports bettor I know will not bet any games prior to June for several reasons.
Early in the season the weather can be bad at certain parks.
Some managers are still experimenting with their line ups.
Many good pitchers get off to a slow start at the beginning of the season.
Spend the first few weeks studying the teams rather than betting them. The baseball season is long and there will be plenty of opportunities for betting the games.
2. Bet the UnderdogsMost professional sports bettors will tell you that the secret to winning is to bet the underdog. When you bet the money line on the underdog you are risking less to win more. The best baseball teams lose at least sixty games a year and the worst teams win close to that same number. The rest of the league falls somewhere in between. Consider that the more favorites you bet, the higher the percentage of wins you'll need to break even. The money line in baseball is always set by the starting pitcher of the teams involved. Look beyond the pitching to the teams other strengths to make your decision.
3. Consider StreaksAfter a favorite has won three games in a row you should lay off betting them at all costs. The odds stack up heavily against you in this situation. The same can be said about teams that are involved in a three-game loosing streak. You should also only bet a team that has won their last game. The mental attitude of a team that is coming off a win is better than after a loss.
4. PitchersBet on a team whose pitcher did well in his last game. Pitchers usually work every fourth day. If a pitcher got clobbered in his last outing he may not be mentally ready to pitch again. You should also consider the teams relief pitcher. If a relief pitcher for a team has been overworked in his last two games you might want to avoid that team.
You should also consider the pitcher from the other team. When two top pitchers go head to head it could come down to a single mistake to decide the game. I would rather bet a top pitcher going against a lesser one than bet on two great pitchers dueling it out.
5. Compare the TeamsBaseball is more than just pitching. You need to look at the strengths and weaknesses of each team. How do the starting players match up against each other? Some teams are more offensive with great hitters , while other teams are stronger in the field playing defense.
6. Consider the ParkHome field advantage is not as important in baseball as it is in football but you should still consider the ball park. Some teams play better in some parks than others. Some players just cant seem to hit well in certain parks. Some parks have their own quirks such as the short left field at Fenway in Boston.
Example: The Yankees are plus 140 over the Boston. If you bet the Yankees and they lose you are minus $140. If you bet Boston and they win you would be paid $130 with a dime line but would be paid only $120 with a 20 cent line.
