The 2025 MLB season is upon us, and fantasy managers are already eyeing potential waiver wire pickups to adjust their rosters following injuries and promising spring performances. With notable names like Shane McClanahan and Vinnie Pasquantino sidelined, the search for replacements intensifies. Players available in fewer than 40% of Yahoo leagues include promising rookies and seasoned players who could significantly impact fantasy teams.

Kristian Campbell of the Boston Red Sox is trending as the starting second baseman, showcasing impressive stats from the previous season and a strong spring. Christian Encarnacion-Strand, despite a rough 2024, is showing potential value as he secures a spot in the Reds' lineup. Wilyer Abreu, recovering from an illness, could emerge as a key outfield contributor. Other names worth monitoring include Jacob Wilson, Hayden Birdsong, and Reese Olson, all of whom present intriguing options for savvy fantasy owners looking to bolster their pitching and batting.
