looks like the phillies were the first team to take advantage of the potential transaction exemptions by apparently putting four players on the special covid-19 injured list, and then adding others to their player pool. the media is referring to this as "an outbreak". when a player is placed on the injured list, it's common for fans to know what the injury is. with the covid-19 injured list, we may not formally know because of privacy laws, but astute persons will be able to draw reasonable conclusions--especially after the fact (i.e. a replacement player isn't subjected to normal outright waivers when removed from the 40-man roster and returned to the player pool, and/or a player is activated from the injured list before the minimum 10 days has passed). this may be an advantage for players not on the 40-man roster with major league experience when there is "an outbreak", because they can be added to the 40-man roster and then returned to the player pool without outright waivers once the "outbreak" player returns to the active roster. again, a player doesn't have to test positive to be placed on the covid-19 list. if he has confirmed exposure to someone who tests positive, he can be placed on the covid-19 list. will clubs be able to abuse this rule by placing two or three underperforming players with no symptoms who were playing alongside or against a player who tested positive, and then activate keon broxton, shelby miller and drew rasmussen--knowing full well that none of them would have to be exposed to waivers to return them to the player pool? (i am assuming that a player previously outrighted to the minor leagues would not be able to refuse any subsequent outright assignment and become a free agent.) i expect grievances to be filed by players--especially those who happen to have played alongside or against a player who tests positive. what was the frequency and duration of contact? does that constitute placement on the covid-19 injured list? this could get ugly . . . and give lots of power to clubs regarding roster flexibility. i got this wrong, and i apologize. after re-reading the tweets referenced above, i realized i needed to do more digging, and found this excellent article written by a lawyer who's seen the 101-page manual outlining the 2020 mlb season and the collective player pool (cpp). this "outbreak clause" only affects players in the club player pool at alternate camp who are placed on the special covid-19 injured list: thus, the brewers do not have any roster management advantage because eric lauer, angel perdomo and luis urias were all placed on the covid-19 injured list simultaneously. my apologies again for misunderstanding this clause.
