As the World Series wraps up and the Hot Stove season gets cooking, we've got you covered on what you need to know:

Fifth day after the World Series: The deadline for teams and players to make decisions on contract options, the deadline for clubs to reinstate all players on the 60-day injured list and the deadline for clubs to tender qualifying offers (3 p.m. MST). Also, the “quiet period” ends and Major League free agents are free to sign with any club as of 3 p.m. MST.

What's the payroll going to be? 
The Diamondbacks opened last season with a club-record payroll of around $195 million. While club officials have said that number will be lower in 2026, GM Mike Hazen emphasized that he will have more than enough payroll to field a team that should compete for a postseason berth.  
 
The team never announces what its payroll will be in advance. It's worth keeping in mind that managing general partner Ken Kendrick has found ways to expand the budget the past two offseasons when there was a unique opportunity.
