Heading into Week 18 of the 2025 season, several key fantasy baseball players have faltered, raising questions about their roster viability. Jacob Wilson of the Athletics, once a hot commodity, has plummeted to a .185 average in recent games yet may still be a hold for managers needing batting average help in larger leagues. Conversely, Clayton Kershaw's struggles suggest a drop in most 12-team formats, as his strikeout rates have declined significantly. Kris Bubic's shoulder injury makes him a sell candidate, potentially leaving managers with little time to capitalize on his successes before the playoffs. Zach McKinstry and Spencer Steer are also facing critical decisions: McKinstry’s slump and versatility might not justify a roster spot, while Steer's recent performance calls for a drop in most leagues as well. The landscape ahead looks challenging for these players as fantasy managers weigh their options carefully.
