I cant really get a good answer from the support ticket. They refered me to a knowledge base that says he should be using option years.
"All players start with 3 at the beginning of their career. The first time a player is added to a club's 40-man roster, his option clock starts ticking. Any subsequent season in which the player accrues 20 or more days on optional assignment (i.e. days on a minor league club from the start of the regular season until the team's final game including playoffs), an option year will be burned. If he's on the big league club for the season or on optional assignment for less than 20 days during the season, he doesn't burn an option. During a season in which a player has options, he may be demoted/recalled at will. Once his options are gone, he must go through waivers before he may be demoted or removed from the 40-man roster."
I responded asking why Ducey has not used any options and they responded back with..
"Options work exactly the same way. If they are on the 40 man roster and spend at least 20 days in the minor leagues in a season, they will use an option year. If they are assigned to the ML roster and stay there, they will not use an option year."
Dont think they are understanding the situation very well... "Options work exactly the same way. If they are on the 40"All players start with 3 at the beginning of their career.
