I believe that when the rosters expand on Sep. 1 and a player is added to the 40-man it doesn't trigger the option process. The simple explanation is that an MLB team owns a player for 6 years. The first 3 are guaranteed and begin with players first season as a pro. The next three are the "option" years and it doesn't necessarily last for three seasons. If a player is brought up on Aug. 31 his first year kicks in but if the team waits until Sep. 1. it doesn't.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
