2027 roster planning
Roster and contract data checked October 18, 2026. These are model comparisons, not reports of player availability.The finder uses the Offseason view (2027 on). Offers opened in the builder use the same view. Completed-season playoff odds do not restrict the offseason player pool.
Each of the 8 position groups is compared with the same position on every other club: 45% season-to-date fWAR rank and 55% 2027 projected fWAR rank. fWAR means FanGraphs wins above replacement. Rotation, bullpen, and outfield are evaluated as multi-player units. The estimated upgrade compares a target with the selected team's marginal starter. Targets are then sorted by fit, which weighs control, age, health, and trade protection. These inputs do not establish availability.

Starting points, not rumors. Packages use positive-value prospects and cost-controlled MLB players, avoid trading an incumbent from the selected hole, and show only one-to-three-player combinations within 30% of the current model—not a club’s private preferences.
