As Week 6 of the 2025 fantasy baseball season approaches, savvy managers are seeking opportunities to enhance their rosters through strategic trades. Identifying undervalued players to buy low can turn the tide for teams struggling in the standings, while moving on from overvalued players can prevent future disappointments.

Dylan Cease of the San Diego Padres is highlighted as a prime candidate to target. Despite a rough start and a 5.76 ERA, Cease's history of consistency and upcoming favorable matchups against teams like the Pittsburgh Pirates, Los Angeles Angels, and Toronto Blue Jays suggest a potential rebound is on the horizon. Meanwhile, Cincinnati Reds' Matt McLain is another buy-low option. His slow start is understandable given his previous injuries, and his peripherals indicate he possesses the talent to improve as the season progresses.

On the flip side, players like Noelvi Marte and Andy Pages are flagged as overvalued assets. Marte's impressive early numbers may be misleading due to poor underlying metrics, while Pages' recent hot streak may not be sustainable. Fantasy managers should consider trading these players before their values decrease. In contrast, acquiring players like Cease and McLain could provide substantial returns as the season progresses.
