1. Using todays Cinn/SF game as an example: a lot of people will look at Bumgarner starting for SF thinking they should win, but these 1st couple of weeks of preseason - pitchers are on a inning and pitch count - usually no more then 2 innings and around 45 pitches.
2. This is also true of all starters in the field, there will be a lot of 2/3A players out there trying to get into the big leagues.
If you are not familiar with the players for the team you are looking to place a wager on, it would be a good idea to go lit or wait a couple weeks till the starters play more.
Good Luck this Baseball season all.
