First base, once a bastion of power hitters, has seen its depth dwindle, making it crucial for fantasy owners to target emerging prospects. The offseason's shakeups led to a carousel of first basemen across teams, complicating matters for those drafting early. While many sought-after prospects are still a year away from contributing, a few like Jac Caglianone, Tyler Locklear, and Bryce Eldridge are on the verge of breaking into the majors, offering potential boosts for fantasy teams. Caglianone, for instance, is impressing in spring training, and his power could make him a valuable addition to a lineup.

Locklear's recent performance shows promise, though he faces stiff competition within the Mariners roster. Meanwhile, Eldridge’s recent struggles in higher minors make his immediate value uncertain, but he could be worth monitoring for mid-season call-ups. Similarly, Deyvison De Los Santos’s power potential is high, but concerns about his strikeout rates must be addressed before he can be relied upon in a fantasy context. Understanding these prospects and their trajectories will be key for fantasy managers looking to exploit the first base position this season.
