The deadline for tendering contracts to players on the 40 man roster who are not currently under contract is tomorrow — Wednesday, December 2, 2020, at 7:00 p.m. Central time. Players who are not tendered contracts by that date become free agents.
The so-called “non-tender deadline” results in a second group of players hitting the free agent market, along with those whose contracts expired after the 2020 season and who have at least the six years accrued service time* necessary to qualify for free agency. The players who are non-tendered are usually (though not always) players who are due to potentially receive more in arbitration than their club is willing to pay.
