he was just optioned, so he must stay down for at least 10 days, unless replacing a player put on the disabled list. Does that transfer when you’re traded? Doesn’t seem right. further clarification, an optioned player accrues time spent optioned with his previous organization. for example, when alec asher was acquired via trade with the dodgers on 17 april, he had been optioned 5 april by the dodgers. thus, he already had spent at least 10 days optioned. the brewers optioned him that same day, and would not have been held to a reset clock if the brewers had wished to recall him on let's say, 20 april (just three days later). however, miller wasn't optioned by the rays prior to this trade. as others have pointed out, he was designated for assignment.
