The fantasy baseball landscape is shifting as we enter Week 12 of the 2025 season, prompting managers to reassess their rosters. Key players under scrutiny include Ryan Walker of the San Francisco Giants, who has lost his closer role to Camilo Doval, making him a candidate for dropping despite his decent underlying metrics. Bryce Miller of the Seattle Mariners also finds himself on the IL with ongoing elbow issues, raising the question of his immediate fantasy viability. Meanwhile, players like Logan O'Hoppe and Josh Jung could provide upside despite recent slumps. O'Hoppe's power potential remains intriguing, while Jung benefits from the Texas Rangers' recent offensive resurgence.

William Contreras, a high draft commodity, has struggled to meet expectations, placing him on the hot seat as managers weigh his continued value against available alternatives. The discussion also touches on players like Corey Seager and Geraldo Perdomo, both facing challenges but with potential for resurgence. As the trade deadline approaches, savvy managers must evaluate their options carefully to optimize their rosters for success.
