The first quarter of the 2025 MLB season has concluded, with fantasy managers facing critical decisions as the All-Star break approaches. It's the perfect time to evaluate the waiver wire for potential upgrades to your roster. Players under 40% rostered in Yahoo! leagues are highlighted here, indicating they could provide much-needed boosts as the season progresses. Last week’s recommendations included Otto Lopez and Kyle Stowers among others.

Trevor Story has bounced back dramatically after a rough early season, showcasing strong offensive numbers, including a .347 batting average over his last 24 games. His ability to generate runs and maintain a high OPS makes him a valuable addition. Similarly, Noelvi Marte returned from injury and contributed effectively in his comeback game. Evan Carter has been on fire with a hitting streak and notable speed on the base paths. Eury Perez, a promising pitcher, could elevate any rotation with his strikeout potential, while Justin Wrobleski has shown resilience in the Dodgers’ rotation. Lastly, the recent performances of Ronny Henriquez and Grant Taylor have sparked interest as they step into pivotal roles that could translate into saves.
