再補一下
動用option是指有實際把球員往minor league送才會算動用
When a player is added to the 40-man roster, his club has three “options,” or three separate seasons during which the club may to move him to and from the minor leagues without exposing him to other clubs.
所以像小王這種沒被送下去過的其實都沒用到option
If a player is not sent to the minors during a year, an option is not used.
