With Halloween now behind us, the Seattle Mariners are officially into the month of November. And with that, the business of baseball is set to pick up rapidly, at least for one month until the probable MLB lockout takes hold on Dec. 1 at 9 p.m. PT.

While hiring a new manager is still the most important thing that the Mariners have to do at the present moment, there are several other important dates coming in November that fans should be aware of.

Let's take a deeper look.

The awards show takes place at 5:30 p.m. PT on ESPN and the Mariners have just one representative as a nominee: Second baseman Cole Young.

None of this is surprising, considering the Mariners were one of the worst defensive teams of the last decade in 2026, but that shouldn't overshadow the gains that Young made at the position. There are still questions about his arm, but he played in 161 games and showed more range than he did in his half a season in 2025.

Monday is a big day with many things going on.

1) The Mariners need to have their 40-man roster set before the 2 p.m. PT deadline. The M's current 40-man roster is at 43 players once you account for players on the 60-day injured list who are coming back. The Mariners will have to shed at least three players from the 40-man by designating them for assignment.

2) Monday is also the day that the M's needed to make decisions on contract options. However, they've already done that by exercising their option on Andres Munoz and declining their options on Victor Robles and Bryce Miller. Robles is a free agent, while Miller will simply go through arbitration again.

3) The Mariners also have until 2 p.m. PT to make a qualifying offer to any of their free agents. That QO is worth about $23 million. It's widely expected that Randy Arozarena will get an offer and turn it down, which will net the Mariners draft pick compensation.

These meetings will bring the baseball world together in Las Vegas and will represent the first meaningful chances for teams to talk with other teams - and agents for free agents. If there aren't winter meetings in December because of a lockout, this could be the best chance for Jerry Dipoto to swing a deal or to set up future deals.

Nov. 9 - Rookie of the Year Awards are announced. The Mariners will have no one in contention.

Nov. 10 - Manager of the Year Awards announced, and since Dan Wilson was let go, he won't be winning.

Nov. 11 - Cy Young winners announced, where the Mariners will have no one in contention.

Nov. 11 - Comeback Player of the Year, Reliever of the Year, Hank Aaron Award and All-MLB Teams announced. Arozarena could be in place for an All-MLB team selection.

Nov. 12 - MVP announced

Nov. 17 - Silver Sluggers announced. Arozarena could garner one of those. He's coming off a second straight All-Star appearance.

Assuming the Mariners give Arozarena a qualifying offer, this is the deadline for him to accept or decline it. It's also another chance for 40-man roster tinkering as the M's have until this day to promote qualified minor leaguers to protect them from the Rule-5 Draft. Of course, we don't know if the Rule-5 Draft will actually happen because of the probable lockout.

If the Mariners don't want to bring back any arbitration-eligible players, this is the deadline to not tender them a contract. We covered some of the possibilities earlier this offseason.

The Collective Bargaining Agreement will expire and we will all be left wondering how long the negotiations will go and how contentious they will be. Baseball could be in for a very long and slow offseason.
