The 2025 MLB season presents a unique landscape for fantasy baseball managers at first base, a position that has become increasingly top-heavy. While elite talents like Vladimir Guerrero Jr., Bryce Harper, and Freddie Freeman dominate early drafts, many teams may find themselves scrambling for value later on. However, there are several under-the-radar players poised for breakout seasons. Tyler Soderstrom, Kyle Manzardo, Deyvison De Los Santos, and Nolan Schanuel each have the potential to exceed their current rankings and provide significant returns for fantasy teams.

Soderstrom, coming off a wrist injury, displayed promising power numbers in a hitter-friendly environment. Meanwhile, Manzardo, with limited MLB experience, has shown impressive minor league stats and could capitalize on a change in team dynamics. Deyvison De Los Santos, the 2024 First Base Prospect of the Year, brings raw power, while Nolan Schanuel's consistent performance hints at potential growth. These players offer intriguing options for savvy managers willing to look beyond established stars.
