The last few days have already seen numerous shakeups in coaching staffs and front offices throughout the league, and the action will continue today, the first notable date on the offseason calendar.
The deadline for teams to extend qualifying offers is set for 5 p.m. ET, and free agency will officially begin once the clock strikes midnight.
Starting Monday and continuing through Thursday, front-office personnel will convene in Boca Raton, Fla., for the annual General Managers Meetings.
Then later this month, Major League Baseball will also look back on some of the previous year's best performances with the 2015 awards announcements scheduled for Nov. 9-20.
Shortly after that, the Winter Meetings will follow with a flurry of transactions likely to come out of Nashville, from Dec. 7-10, as the Hot Stove heats up. The Rule 5 Draft is scheduled for the final day of the Meetings.
Here's a quick look at what else we've seen so far:
Royals make qualifying offer to Gordon
Free-agent-to-be Alex Gordon became the first household name to receive a one-year qualifying offer after the 31-year-old outfielder declined his player option to remain with the World Series-champion Royals.
This year's qualifying offer is valued at $15.8 million, an average annual salary of the top 125 contracts in baseball. Players will then have one week to accept or decline the offer. If they decline the offer and sign with another team, their previous team will receive a compensatory pick in the 2016 Draft, while their new club surrenders its top unprotected selection.
Notably, in the three years under the current Collective Bargaining Agreement, 34 players have been extended a qualifying offer and all have turned it down. Could 2015 bring an end to that trend?
Manager vacancy remains in Los Angeles
One managerial opening still remains unfilled, as the Dodgers have yet to name a successor to departed skipper Don Mattingly.
President of baseball operations Andrew Friedman is in the midst of a search that includes both internal and external candidates. The club has already interviewed former Dodgers player Kirk Gibson and has received permission to speak with Mets bench coach Bob Geren, who previously worked with Dodgers general manager Farhan Zaidi in Oakland.
Former Padres skipper Bud Black is also expected to be in a mix that includes rumored candidates Gabe Kapler, Ron Roenicke, Tim Wallach, Dave Roberts, Darin Erstad and Dave Martinez.
