So that’s it—the 2025 Major League Baseball regular season is over. Now you can finally breathe and relax, right? Wrong! Not if you play dynasty or keeper league fantasy baseball. For you, this is just the beginning. October baseball is more than just watching your team race for a trophy, it means watching for some key fantasy points.
For those new to the concept, a dynasty or keeper league allows managers to retain players into the following season. Often, that involves contracts, salary increases, and tough roster decisions that can define the future of your team.
The savvy dynasty manager will watch the MLB playoffs not just as a fan but with an eye toward the future. How a player finishes the year could shape perceptions going into next season. On top of that, the offseason will bring inevitable changes—free-agent signings, trades, and new roster situations. This is when the real work begins.
Congratulations to all the league champions this season. Winning a fantasy title is no small feat, requiring skill, patience, and often a little luck. For those who fell just short, remember that next year is closer than it feels. The offseason offers a chance to reset, evaluate, and prepare for another run at the crown.
But don’t make the mistake of taking the next few months off. To gain an edge in dynasty or keeper formats, you need to start your offseason work immediately. Track player health, monitor potential role changes, and evaluate minor leaguers who may soon contribute. The managers who stay active in October, November, and December are often the ones celebrating next September.
The best dynasty and keeper league managers already know: there is no true offseason. The competition never stops, and preparation is the difference between another middle-of-the-pack finish and raising the trophy.
