still unknown:
--does the special covid-19 injured list still exist and does it has the same rules as before? (the player is removed from the 40-man roster; an outbreak allows for replacement players to simply be returned to the minor leagues without outright waivers or optional assignment; and clubs can carry taxi squads up to five players on road trips.)
--can clubs still place an unvaccinated player on the special covid-19 restricted list even if he tests negative due to close contact via contact tracing? that's why jace peterson went on the restricted list last season when christian yelich tested positive . . . even though peterson tested negative, because he refused the covid-19 vaccine, he had to be removed from the roster and miss a minimum of seven days.
--does the return of a replacement player during a covid outbreak (who had been on optional assignment prior to the outbreak) to the minor leagues after a covid outbreak count as an optional assignment and thus, against the maximum of five instances allowed? last season, during an outbreak, clubs could return a replacement player who had been on the 40-man roster without an optional assignment. this is an important technicality with the new cba, if the same rule still applies. and is an outbreak still defined as three or more players?
--how long can minor league rehab assignments last? it had been 20 days for a position player and 30 days for a pitcher.
--what's the deadline for the opt-out clause for non-roster invitees who must be told they've made the opening day roster or paid a $100,00 retention bonus?
--and will the qualifications for a non-roster invitee to require an opt-out clause and retention bonus be the same as they were in the past (must have at least six years of service time, and must have finished the 2021 season on a major league roster or major league injured list)?
--we now know that the trading deadline is flexible per the commissioner, but we don't know the actual trading deadline for 2022.
--does a player still retain his option year if he spends less than 20 days on optional assignment in a single season?
--can clubs still petition mlb for a fourth option year if a player spent one of his burned option years with a significant injury? presumably, the fourth option granted to j.c. mejia for the 2022 season remains intact.
--are the contracts for jandel gustave, jace peterson, pedro severino and rowdy tellez fully guaranteed as they were signed under the previous collective bargaining agreement?
--we also need to verify roster expansion for: doubleheaders, games in september, and for doubleheaders in september.
with regards to roster management, can anyone else think of anything that's still unknown?
