Opt out was for the 25-man roster, but because Choi had an option remaining, he had no say whether the Brewers could send him down. A lot of times, when a player signs a minor league deal with an opt-out, they have no options remaining, which gives them even more leverage. Yeah, I think we had discussed the Choi situation in after Opening Day. Since he had technically been on the Major League (25 man) roster on or before May 15, his opt-out was voided. Shrewd move, although questionable ethically (similar to the Davies situation where he was optioned over an all-star break).
